Question

When will the magnitude of speed and velocity be same?​

Answer 1

Answer:

The speed of a body gives us an idea of how slow or fast that body is moving. For example if a car is running slow, we say that its speed is low. And if a car is running fast, then we say that its speed is high. Therefore, speed of a body is the distance travelled by it per unit time. On the other hand velocity of a body is the distance travelled by it per unit time in a given direction. The speed of a body or here, car gives an idea how fast it is moving. Thus to know the exact position of a moving car we should also know the direction in which the car is moving. So, both speed and velocity is important. We should know the speed of the car as well as the direction of speed. Let us find from this article that why the speed and velocity are not always equal in magnitude.

First we will see how the magnitude of speed and velocity of a moving body is equal.
