Question

define and give units of following 1 speed 2 velocity 3 acceleration

Answer 1

1)Speed = m/s
It is distance covered with respect to time.

2)Velocity = m/s
It is displacement covered with respect to time.

3)Acceleration = m/s^2
It change in velocity with respect to time.

Answer 2

1) speed: Distance covered by time taken

2) velocity: The rate of distance covered in specific direction

3) acceleration: Rate of change in speed or velocity
