Question

Define the rate of change of velocity, with solved example.​

Answer 1

Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion (or both).

Answer 2

answer:-

The rate of change of velocity is ACCELERATION. Like velocity, acceleration is a vector and has both magnitude and direction. The velocity of an object is the speed of an object moving in a definite direction. Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

Acceleration = Change in Velocity/ Time taken SI unit: ms2
