Cbse | Rate Of Change Of Velocity : Concept Of Acceleration | Part 4

Assertion : For a particle, acceleration-time graph gives the velocity. Reason : Rate of change of velocity is acceleration.

Acceleration is defined as the rate of change of velocity. Suppose we call the rate of change of acceleration as SLAP ?. (i) What is the unit of SLAP . (ii) How can we calculate instantaneous SLAP ?

Assertion: A body having non zero acceleration can have a constant velocity. Reason: Acceleration is the rate of change of velocity.

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

Explain briefly the concepts of velocity and acceleration.

The unit for the rate of change of velocity will be

Statement-I : When velocity of a particle is zero then acceleration of particle is zero. Statement-II : Acceleration is equal to rate of change of velocity.

Assertion: In a uniformly accelerated motion, acceleration the graph is straight line with positive slope. Reason: Acceleration is rate of change of velocity.
