Newton’s Second Law In Action

Rockets traveling through space encompass all three of Newton’s laws of motion.

If the rocket needs to slow down, speed up, or change direction, a force is used to give it a push, typically coming from the engine. The amount of the force and the location where it is providing the push can change either or both the speed and direction.

Now that we know how a massive body in an inertial reference frame behaves when it subjected to an outside force, such as how the engines creating the push maneuver the rocket, what happens to the body that is exerting that force? That situation is described by Newtons Third Law of Motion.;

Work Force And Energy

* Work is the measure of a quantity that is capable of accomplishing Macroscopic Motion of a System due to the action of a Force over a Distance.* Force is the agent of change, and Work is a measure of the change.* The Force does the Work, not the agent that created the Force. Do not confuse the work you do to create a force with the work done by the force you create; they are not the same. The force you exert holding a 100 pound barbell above your head does no work on the barbell while the barbell is at rest, but you do work to create that force.* Work is related to the distance a force moves an object and not the time it takes to move the object. * A Force does no work unless the system is free to move “along the direction” of the Force applied. When a Force and the object’s displacement are perpendicular, the work done by the force is zero.* The Energy transferred into a system by the action of a Force is the Work done on the System.* If system A does work then energy flows out of the system A. If another system does work on system A then energy flows into the system A from the other system.* There is no such thing as pure energy. Energy is a property of a system which depends upon the system’s mass and speed, and sometimes on its position.* Mass and Energy have much in common. Einstein’s famous equation E = mc2 shows that mass is itself a form of “stored” energy.* Energy is a scalar quantity. Like mass, it has no direction associated with its magnitude.

Work Done By A Constant Force:

• Work is usually defined in terms of the dot product because it is only the component of the force along the direction of motionof the object – F cos – which does any work and the dot product nicely expresses product in a compact form. One corollary is that the perpendicular component of the force can never do any work on object.

General Derivation Of The Workenergy Theorem For A Particle

For any net force acting on a particle moving along any curvilinear path, it can be demonstrated that its work equals the change in the kinetic energy of the particle by a simple derivation analogous to the equation above. Some authors call this result workenergy principle, but it is more widely known as the workenergy theorem:

The remaining part of the above derivation is just simple calculus, same as in the preceding rectilinear case.

Coasting Down A Mountain Road

Consider the case of a vehicle that starts at rest and coasts down a mountain road, the workenergy principle helps compute the minimum distance that the vehicle travels to reach a velocity V, of say 60;mph . Rolling resistance and air drag will slow the vehicle down so the actual distance will be greater than if these forces are neglected.

Let the trajectory of the vehicle following the road be X which is a curve in three-dimensional space. The force acting on the vehicle that pushes it down the road is the constant force of gravity F = , while the force of the road on the vehicle is the constraint force R. Newton’s second law yields,

F

This formula uses the fact that the weight of the vehicle is W = mg.

Derivation For A Particle In Constrained Movement

In particle dynamics, a formula equating work applied to a system to its change in kinetic energy is obtained as a first integral of Newton’s second law of motion. It is useful to notice that the resultant force used in Newton’s laws can be separated into forces that are applied to the particle and forces imposed by constraints on the movement of the particle. Remarkably, the work of a constraint force is zero, therefore only the work of the applied forces need be considered in the workenergy principle.

To see this, consider a particle P that follows the trajectory X with a force F acting on it. Isolate the particle from its environment to expose constraint forces R, then Newton’s Law takes the form

F

. }v^,\quad }\quad v=}.}

Notice that this formula uses the fact that the mass of the vehicle is m = W/g.

What Do The F And F Numbers Written On Lens Mean

On this particular lens rim is written “F:2.6 f=3.8mm”.What does it mean? Focal point 3.8 mm and aperture 1/2.6 of the focal point ???

• 4Aug 16 ’18 at 21:00
• 1I don’t see that other question answering this one, at least not obviously. First, this labeling is different on the front ring of the lens than it often is in listed lens names , and second, this isn’t a brand covered by the detailed answers.

The F 2.6 is the f-stop, “speed” or how light sensitive the lens is. A lower number means more light can hit the sensor.A lower number also means you can easier get the background out of focus.

The f=3.8 mm is the focal length of the lens. This is the number that describes if it’s a wide angle lens or a telephoto lens .

In this case 3.8 mm needs to be multiplied with the crop factor of the sensor if you want to get the “35 mm equivalent”. After googling I see that the 35mm equivalent is a 37 mm lens.

Also note that the camera only has digital zoom. The result will be, let’s just say, not what you hoped for if you use the digital zoom.My advice is to look for something with optical zoom. It’s a massive difference. Even a used old camera is probably better, if you ever need the zoom. If you never ever need the zoom than this is probably fine.

It seems their marketing department needs to learn how the focal length works, since this diagram shows a longer focal length as wider. That is backwards.

Derivation For A Particle Moving Along A Straight Line

In the case the resultant forceF is constant in both magnitude and direction, and parallel to the velocity of the particle, the particle is moving with constant acceleration a along a straight line. The relation between the net force and the acceleration is given by the equation F = ma , and the particle displacements can be expressed by the equation

s

Work Done By A Variable Force

Calculating the work as “force times straight path segment” would only apply in the most simple of circumstances, as noted above. If force is changing, or if the body is moving along a curved path, possibly rotating and not necessarily rigid, then only the path of the application point of the force is relevant for the work done, and only the component of the force parallel to the application point velocity is doing work . This component of force can be described by the scalar quantity called scalar tangential component , where is the angle between the force and the velocity). And then the most general definition of work can be formulated as follows:

Work of a force is the line integral of its scalar tangential component along the path of its application point.

If the force varies we need to use calculus to find the work done. If the force is given by F then the work done by the force along the x-axis from a to b is:

W

as presented above.

Notice that only the component of torque in the direction of the angular velocity vector contributes to the work.

Count Iblis said:SI units are not consistent. In SI units we use inconsistent units for Time, Length, Mass, Temperature etc. etc. This comes at the price of having to introduce extraneous conversion factors in formulae.

F=maHow do we define m and F? So what does F and m really means??

mexperimentally

Still, I have a sense that these experiments only shows that this definition of m and F is consistent. The F=ma doesn’t tell us much thing.

What Does The Force Mean In $dp/dt$ Form

One was to write Newton’s laws is:

$$F=\frac.$$

I don’t understand what is the force there. I believe that $F$ is the net external force on the system. So supposedly I have a mass which is moving right and then it collides with another mass which is hanging on a rope from the ceiling.

Supposedly my system is the mass, mass on rope and the Earth. This would make forces of gravity internal. The only external force is the tension on rope. Now, would the tension of the rope be before the collision, or after the collision? The mass on rope swings up obviously. At that particular instant when it is at max angle, the $T$ is obviously not equal to $T$ when before collision. So does the $T= dp/dt$, is the $T$ before or after collision?

Ok edit. In this system the momentum is not conserved right? Since there is a net external force $T$. So I supposed taking ceiling as part of the system would make $T$ an internal force.
