What is the Rate of Change of Velocity known as?

By Mandeep Kumar|Updated : July 28th, 2022

The measure of the rate of change in the velocity of an object per unit of time is called Acceleration. The formula to determine the acceleration of an object is given by acceleration = change in velocity/time taken.

Answer: The rate of change of velocity is referred to as acceleration.

When the velocity of an object changes from the initial value to the final value in a given time then the value acceleration can be obtained by: acceleration = (final velocity – initial velocity)/time. Its SI unit is ms–2.

More about Acceleration

The information related to acceleration has been elaborated below:

  • The value of acceleration is positive when it is in the direction of velocity.

  • Its value is negative when it is in the opposite direction of velocity.

  • Acceleration is said to be uniform if the velocity of an object increases or decreases by equal amounts in equal intervals of time. Example: Motion of freely falling body.

  • Non-uniform acceleration is defined as the change in the velocity of an object at a non-uniform rate. Example: change in the speed of the car by unequal amounts in equal intervals of time.

Summary:

What is the Rate of Change of Velocity known as?

The rate of change of velocity is known as acceleration. The speed of an object moving in a certain direction is called velocity.
