## Why Is It Called Metric

This name was derived from the Greek word, metron, meaning a measure. The physical standard representing the metre was to be constructed so that it would equal one ten-millionth of the distance from the North Pole to the equator along the meridian running near Dunkirk in France and Barcelona in Spain.

The ideal method to fully grasp the method by which the universe operates is always to learn quantity for each and every particle, or about vf. However, since youve never heard of this how can you go about understanding relating to it? Let us take a review of vf in math, and what it way for your requirements personally.

Vfs fundamental definition is the amount of thing in a given quantity. apa bibliography article Because we understand that it, is made up of atoms and electrons, you notice, matter. In mathematics, this usually means there is a minimum sum of thing which can exist in just about any particular volume.

If you understood anythings volume, what will you really do with it? You might decide to make an effort to secure more of it, or you might try to shoot it off. In mathematics, you can use it to define the amount of thing in a volume. To put it differently, if you know the size of the particle, you still know the volume.

Now you are aware about what it will be, lets learn about this. What is vf in math? It is nothing more than the range of atoms and molecules . As a way to learn the number of molecules or atoms are in certain volume, you have to know the amount.

There is also an upper limit to the amount, however this is important. This limit will be able to help you calculate just a little more matter you might have than you understood.

## Alternative Final Velocity Calculator Equations

You can use the other kinematic equations as appropriate for whichever situation you’re working with. If you knew the distance an object traveled , along with the initial velocity and time it took to travel that distance, you could calculate final velocity using the equation:

Make sure to use the correct units in these calculations.

## Example 1 Calculating Displacement: How Far Does The Jogger Run

A jogger runs down a straight stretch of road with an average velocity of 4.00 m/s for 2.00 min. What is his final position, taking his initial position to be zero?

**Strategy**

The final position *x* is given by the equation

To find *x*, we identify the values of *x*0, \bar, and *t* from the statement of the problem and substitute them into the equation.

**Solution**

1. Identify the knowns. \bar=4.00\text, \Delta t=2.00\text, and _=0\text.

2. Enter the known values into the equation.

**Discussion**

Velocity and final displacement are both positive, which means they are in the same direction.

The equation x=_+\bart gives insight into the relationship between displacement, average velocity, and time. It shows, for example, that displacement is a linear function of average velocity. On a car trip, for example, we will get twice as far in a given time if we average 90 km/h than if we average 45 km/h.

Figure 3. There is a linear relationship between displacement and average velocity. For a given time t, an object moving twice as fast as another object will move twice as far as the other object.

## Interesting Facts About Speed And Velocity:

- Galileo Galilei was the first scientist who measures speed as distance over time
- A speedometer is said to be the best example of instantaneous speed
- You can also express a speed of light as 186,282 miles per second
- The speed of sound in dry air can be expressed as 343.2 meters per second
- The escape velocity of Earth is referred to as the speed that needed to escape from Earths gravitational pull. It is expressed as 25,000 miles per hour

## Solving For Displacement And Final Position From Average Velocity When Acceleration Is Constant

To get our first two new equations, we start with the definition of average velocity:

Substituting the simplified notation for *x* and *t* yields

Solving for *x* yields

where the average velocity is

The equation \bar=\frac_+v} reflects the fact that, when acceleration is constant, *v* is just the simple average of the initial and final velocities. For example, if you steadily increase your velocity from 30 to 60 km/h, then your average velocity during this steady increase is 45 km/h. Using the equation \bar=\frac_+v} to check this, we see that

which seems logical.

## What Can We Tell From These Formulas

lets look at **F = Mass **

This formula tells us that we can use one of two methods for changing momentum . We can either increase the force expressed on the left or we can increase the time that the force is being expressed.

Lets look at how this applies in a real life example. Lets an athlete performing depth jumps and he weighs 100kgs and upon landing he is moving at 4m/s. So, our momentum right before ground contact is 100kgs * 4m/s = 400m/s/kg. Now in order to stop this momentum we can use one of two methods

**Force * = 400m/s/kg**

**400kgs * = 400 m/s/kgs**

In both situations thee athlete meets the requirements to stop his momentum. However, the method of accomplishing the task was done in two different ways. The first method used an increase in force and the second relied on an increase in time a lesser force was being applied. Depending on the training goals you may want to emphasize one method over the other.

## What Is The Formula For Velocity

The velocity is said to as the time rate of change of displacement. So, the velocity formula physics is:

$$ v = \frac $$

**Velocity After a Certain Time of Acceleration:**

$$ Final velocity = Initial Velocity + Acceleration \times Time $$

Our total velocity calculator also uses the same velocity calculating formula to calculating velocity accurately.

## Solving For Final Position When Velocity Is Not Constant

We can combine the equations above to find a third equation that allows us to calculate the final position of an object experiencing constant acceleration. We start with

Adding *v*0 to each side of this equation and dividing by 2 gives

Since \frac_+v}=\bar for constant acceleration, then

Now we substitute this expression for \bar into the equation for displacement, x=_+\bart, yielding

## Example 2 Calculating Final Velocity: An Airplane Slowing Down After Landing

An airplane lands with an initial velocity of 70.0 m/s and then decelerates at 1.50 m/s2 for 40.0 s. What is its final velocity?

**Strategy**

Draw a sketch. We draw the acceleration vector in the direction opposite the velocity vector because the plane is decelerating.

Figure 4.

1. Identify the knowns. v0 = 70.0 m/s, *a *= 1.50 m/s2, *t* = 40.0 s.

2. Identify the unknown. In this case, it is final velocity, *v*f.

3. Determine which equation to use. We can calculate the final velocity using the equation v=_+.

4. Plug in the known values and solve.

**Discussion**

The final velocity is much less than the initial velocity, as desired when slowing down, but still positive. With jet engines, reverse thrust could be maintained long enough to stop the plane and start moving it backward. That would be indicated by a negative final velocity, which is not the case here.

Figure 5. The airplane lands with an initial velocity of 70.0 m/s and slows to a final velocity of 10.0 m/s before heading for the terminal. Note that the acceleration is negative because its direction is opposite to its velocity, which is positive.

In addition to being useful in problem solving, the equation v=_+\text gives us insight into the relationships among velocity, acceleration, and time. From it we can see, for example, that

## What Is The Forward Voltage V F

The forward voltage of an LED, VF, is the voltage that must be applied across the leads of the LED, from anode to cathode, in order for the LED to turn on.

**As you can see above, positive voltage must be applied across the LED from its anode to its cathode. If reversed, this is no longerforward voltage but reverse voltage, and the LED will not light up. Forward Voltage is positive voltage applied across the LED’s anode to its cathode. **

Different kinds of LEDs have different forward voltage requirements. Non-bright LEDs tend to require less voltage than bright LEDs, since bright LEDs need more power to work. Typical VLED values are 1.7V for non-high-brightness red, 1.9V for high-brightness high-efficiency low-current red, 2V for orange and yellow, 2.1V for green, and 3.4 to 3.6V for bright white and most blue types.

In order to make sure that this voltage gets dropped across the LED, you should use a voltage greater than the LED’sforward voltage. Use at least 3V supply voltage for lower-voltage LEDs and 4.5V for 3.4V types. Also add a resistor in series with the LEDto limit excess current from burning out the LED, usually so that the current flowing through the LED is about 20mA. Make sure that the currentdoesn’t exceed the maximum current specified on the LED’s datasheet.

## Momentum And Impulse Connection

As mentioned in the previous part of this lesson, momentum is a commonly used term in sports. When a sports announcer says that a team has the momentum they mean that the team is *really on the move* and is going to be *hard to stop*. The term*momentum* is a physics concept. Any object with momentum is going to be hard to stop. To stop such an object, it is necessary to apply a force *against* its motion for a given period of time. The more momentum that an object has, the harder that it is to stop. Thus, it would require a greater amount of force or a longer amount of time or both to bring such an object to a halt. As the force acts upon the object for a given amount of time, the objects velocity is changed and hence, the objects momentum is changed.

The concepts in the above paragraph should not seem like abstract information to you. You have observed this a number of times if you have watched the sport of football. In football, the defensive players apply a force for a given amount of time to stop the momentum of the offensive player who has the ball. You have also experienced this a multitude of times while driving. As you bring your car to a halt when approaching a stop sign or stoplight, the brakes serve to apply a force to the car for a given amount of time to change the cars momentum. An object with momentum can be stopped if a force is applied *against *it for a given amount of time*.*

**Sample problem**

*Solution*

## What Causes A Change In Velocity

Experts depicts that forces are something that affect how objects move they may cause motion, also, they may stop, slow or even change the direction of motion of an object . As force cause changes in the speed or direction of an object, it is said to be that forces causes changes in velocity. Remember that acceleration is said to be change in velocity.

## Why Velocity Matters

Velocity is something that measures motion starting in one place and heading toward another place. No doubt, the practical applications of velocity are endless, but the most well-known reason to find velocity is to analyze how quickly you will reach at a destination from a given point. Velocity really makes it possible to make timetables for travel. For instance, if a train leaves Grand Central Terminal at 1 pm, and you have an idea about the velocity at which the train is moving north, you can easily predict when it will arrive at the Pennsylvania Station.

## What Is Vf2 = Vi 2

Could it be step by step please

This is one of the standard kinematic equations used in physics to track the motion of an object, neglecting friction. In this equation we have vf , vi , a , xf and xi .

To solve for xi, first subtract vi^2 from both sides, giving:

vf^2 – vi^2 = 2a

Next, divide both sides by 2a to get

/ 2a = xf – xi

Finally, subtract xf from both sides:

/ 2a – xf = -xi

But wait! There is one more thing to do. Since we don’t normally want a negative sign in front of the variable we are solving for, simply get rid of it by multiplying the terms on each side by -1 and rearrange things a bit to make it look more pleasant:

xi = xf – / 2a

Hope this helps!
