Rate of Change of Velocity

What are all types of acceleration and explain them

What is Non-uniform Acceleration? Give an example.

What is Uniform Acceleration? Give an example.

A body describes uniformly accelerated motion along a straight line. Which of the following displacement-time graphs shown represent the motion correctly?
 

At what interval does the object with the acceleration-time graph as shown in the figure make uniform linear motion?

A person sitting in a train moving with a constant velocity along a straight line throws a ball vertically upwards, then the ball will

When$x oc t",$ acceleration is constant when $n$
equals

For a body in non-uniform acceleration that velocity does not remain constant. 

What do you mean by non-uniform acceleration?

If a body is having constant acceleration, then that the body is having zero velocity.

When a body is said to be in uniform acceleration, what do you mean by that?

A car starts from rest and achieves a speed of $54 {\mathrm{kmh}}^{-1}$in $3$ seconds. Find its acceleration?

When will you say a body is in the uniform acceleration?

The velocity of a body at the end of $5 \mathrm{s}$ is $30 \mathrm{m} {\mathrm{s}}^{-1}$, at the end of 12 s is $58 \mathrm{m} {\mathrm{s}}^{-1}$ and at the end of 22 s, it is $98 \mathrm{m} {\mathrm{s}}^{-1}$. The body is moving with

Consider the acceleration, velocity and displacement of a tennis ball as its falls to the ground and bounces back. Directions of which of these change in the process?

A parachutist jumps out of an airplane and accelerates with gravity to a maximum velocity of $58.8 \mathrm{m}/\mathrm{s}$ in $6.00$ seconds. She then pulls the parachute cord and after a $4.00$ -second constant deceleration, descends at $10.0 \mathrm{m}/\mathrm{s}$ for $60.0$ seconds, reaching the ground. From what height did the parachutist jump?

The velocity of a body at the end of $5 \mathrm{s}$ is $30 \mathrm{m} {\mathrm{s}}^{-1}$, at the end of 12 s is $58 \mathrm{m} {\mathrm{s}}^{-1}$ and at the end of 22 s, it is $98 \mathrm{m} {\mathrm{s}}^{-1}$. The body is moving with

When is an object said to be in non-uniform accelerated motion?

A body having non-uniform acceleration will have constant velocity across the journey.

A ball is projected vertically upwards with a velocity v. It comes back to ground in time t. Which v-t graph shows the motion correctly?
