If the acceleration of a particle is constant in magnitude but not in direction,what type of path is followed by the particle?

Draw displacement-time graphs for the following situations:
$(i)$ When a body is stationary.
$(ii)$ When a body is moving with uniform velocity.
$(iii)$ When a body is moving with variable velocity.

The displacement of a body is proportional to the cube of the time lapsed. The magnitude of the acceleration is

What is a velocity-time graph? State how it can be used to find:
$(i)$ The acceleration of a body.
$(ii)$ The displacement of the body.
$(iii)$ The distance travelled in a given time.

State whether the following statement is true or false:
Acceleration is defined as the rate of change of velocity.

The velocity-time graph (Fig.) shows the motion of a cyclist. Find $(i)$ its acceleration $(ii)$ its velocity and $(iii)$ the distance covered by the cyclist in $15\,s$.
