## Solved Question For You

**Q-****What is the difference between magnitude and intensity?**

**Ans- **A Magnitude is simply a quantitative number while intensity gives us the idea of impact. Lets understand it with an example suppose two persons are riding a car and a bike at the same speed of 100km/hr.

The person riding the bike will most probably damage the engine at such a speed. On the other hand, speed will not have any impact on the cars engine.

Now we can say that the magnitude of both car and bike is same i.e 100km/hr, but both will have a different impact because of the intensity. Intensity changes with the impact while magnitude remains the same.

## What Is Magnitude This Question Is Taken From Class 9th Motion Chapter Of Science

In physics, magnitude generally refers to distance or quantity. In relation to movement, magnitude refers to the size of an object or its speed while traveling.

Distance, mass, speed and velocity in physics are divided into vectors and scalars. A vector refers to an object with two characteristics, which are magnitude and direction. Magnitude refers to an object’s size or quantity, while direction means that a vector simply moves from one point to another. For example, a bowling ball has a greater magnitude than a golf ball. The bowling ball has direction when it rolls down the bowling alley. Direction describes an object’s movement, and it also creates a distinction between velocity and speed.

## What Is The Difference Between Speed And Velocity Class 9

Speed is the distance covered in unit time whereas velocity is the displacement covered in unit time. Speed is a scalar quantity and velocity is a vector. Speed only determines the magnitude that is how fast is a body moving whereas velocity determines the direction also that is in which direction the body is moving.

**What is meant by speed in physics?**

Speed. Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.

**What is an example of velocity?**

Velocity is the rate of motion, speed or action. An example of velocity is a car driving at 75 miles per hour. The speed and direction of motion of a moving body. Velocity is a vector quantity.

## What Is Magnitude In Physics When It Comes To Scalar Quantity

We have basically two types of quantity- scalars and vectors. Both of them have a magnitude in common. Scalar quantities have specific magnitude with the proper unit. Some of the scalar quantities are mass of an object, temperature of a body, time of the event, and the distance between the two points.

We can combine their magnitudes with the ordinary rule of algebra having the same unit. We can add, subtract, divide and multiply the magnitudes of scalar quantity, just as the ordinary number.

Let us look at an example we have three sides of a triangle as 10m, 8m, and 6m. Then its perimeter will be the sum of its three sides, 10m+8m+6m = 24m. We add only the magnitudes and unit remains the same. Similarly, if we need to find the temperature difference between two bodies, we simply subtract the magnitudes of temperature.

**The magnitude of a Real number** The magnitude of a real number is usually termed the absolute value or modulus.

Just as the magnitude of an earthquake indicates how huge the earthquake is, the **magnitude** of a mathematical expression tells us how significant that term is. In math, this means how far away the term is from zero or origin.

**The magnitude of a Vector- **An object which possesses both the magnitude as well as direction is called a vector quantity. To find the magnitude of a vector, we require to calculate the length of the vector. Quantities for example velocity, force, momentum, displacement, etc. are called vector quantities.

## How Is Order Of Magnitude Calculated

Order of magnitude refers to the class of scale of any numerical value in which each class contains values of a fixed ratio to the class before it.

On a logarithmic scale — such as base 10, the most common numeration scheme worldwide — an increase of one order of magnitude is the same as multiplying a quantity by 10. That increases the exponent by one to the next nearest power of 10. An increase of two orders of magnitude is the equivalent of multiplying by 100, or 102. In general, an increase of *n* orders of magnitude is the equivalent of multiplying a quantity by 10*n*. Thus, 2,315 is one order of magnitude larger than 231.5, which in turn is one order of magnitude larger than 23.15.

As values get smaller, a decrease of one order of magnitude is the same as multiplying a quantity by 0.1. A decrease of two orders of magnitude is the equivalent of multiplying by 0.01, or 10-2. In general, a decrease of *n* orders of magnitude is the equivalent of multiplying a quantity by 10*-n*. Thus, 23.15 is one order of magnitude smaller than 231.5, which in turn is one order of magnitude smaller than 2,315. As the order of magnitude of a number gets smaller, the decimal moves to the left.

## Magnitude Of A Vector Definition

The magnitude of a vector is the length of the vector. The magnitude of the vector $\vc$ is denoted as $\| \vc \|$. See the introduction to vectors for more about the magnitude of a vector.

Formulas for the magnitude of vectors in two and three dimensions in terms of their coordinates are derived in this page. For a two-dimensional vector $\vc=$, the formula for its magnitude is\begin \| \vc \| = \sqrt.\endFor a three-dimensional vector $\vc=$, the formula for its magnitude is\begin \| \vc \| = \sqrt.\end

The formula for the magnitude of a vector can be generalized to arbitrary dimensions. For example, if $\vc = $ is a four-dimensional vector, the formula for its magnitude is \begin \| \vc \| = \sqrt.\end

## What Is Order Of Magnitude

An order of magnitude is an exponential change of plus or minus 1 in the value of a quantity or unit. The term is generally used in conjunction with power-of-10 scientific notation.

Order of magnitude is used to make the size of numbers and measurements of things more intuitive and understandable. It is generally used to provide approximate comparisons between two numbers. For example, if the circumference of the Sun is compared with the circumference of the Earth, the Sun’s circumference would be described as many orders of magnitude larger than the Earth’s.

## How To Calculate Magnitude Of A Scalar

Here are some real-life examples to help you understand. Scalar magnitude calculation is very simple which we do every day. **We calculate scalar magnitude 90 percent of the time in real life.** For example

1. Suppose you take a bus journey from New York to Boston. When you arrived in Boston, a friend of yours asked you, How much distance did you travel in total?

And when you tell your friend I have traveled 346 km. In this case, 346 km is the magnitude of the distance.

2. Suppose you mix 250 ml of water in one liter of pure milk. Then now your total amount of milk will be 1250 ml. In this case, the calculation of magnitude has followed the rule of simple addition.

3. You bought a dozen bananas from a fruit shop for one dollar per banana. And in this case, your total bill will be 12 dollars.

## How To Calculate Magnitude Of A Vector

Vector quantities too have magnitude with direction. Some of the vector quantities are displacement, velocity, acceleration, force, etc. We call the magnitude of a vector as its absolute value.

We can determine that two vectors will only be equal if both have the same magnitude as well as direction. If we multiply a vector with a positive number, its magnitude will change but the direction remains the same. Similarly, if we multiply a vector with a negative number, its magnitude and direction both will change.

## What Is Magnitude In Physics

In Physics, magnitude is defined as the maximum extent of size and the direction of an object. Magnitude is used as a common factor in vector and scalar quantities. By definition, we know that scalar quantities are those quantities that have magnitude only. Whereas vector quantities are those quantities that have both magnitude and direction.

There are different ways in which magnitude can be used. Some of them are:

- Magnitude of earthquake
- Magnitude of charge on an electron
- Magnitude of force
- Magnitude of gravitational force

**Q. What is the meaning of magnitude in physics?**

**Answer:** A magnitude is a unit of measurement that is used to specify the size or intensity of an event. It has been defined as the amount by which something out of its usual quantity exceeds another. A magnitude and its relative value are often represented on the same scale, for example, a magnitude five earthquake or a 10-foot wall. Magnitude may also be used to specify the size of an object in comparison to other objects. For instance, a magnitude 1 star is one-fifth as bright as a magnitude 2 star .

The unit of measurement for mathematical variables is called a scalar or simply the scalar of that variable. In this case, the scalar value is, by definition, the magnitude of that variable. The magnitude of a quantity is sometimes called absolute magnitude to distinguish it from relative magnitude, which specifies the ratio of that quantity to a standard. The former magnitude has units of length, area, or time and does not depend upon the unit in which its measured, whereas relative magnitude depends on its unit.

## What Is The Difference Of Speed And Velocity

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an objects movement. Put another way, speed is a scalar value, while velocity is a vector. In its simplest form, average velocity is calculated by dividing change in position by change in time .

**Whats the difference between speed and velocity in math?**

So, whats the difference? Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an objects movement. Put another way, speed is a scalar value, while velocity is a vector.

**How are velocity and speed used in everyday life?**

The terms velocity and speed give us an idea of how fast or slow an object is moving. Quite often, we come across situations where we need to identify which of the two or more objects is moving faster. One can easily tell the fastest of the two if they are moving in the same direction on the same road.
