Which of the following objects is accelerating?
- a car moving at a constant speed in a straight line
- a car moving at a constant speed through a curve
- a flower pot falling from a 2nd story window
- a patriotic statue in center of the park

Answer : The correct options are, (b) and (c)

Explanation :

Acceleration can be defined as the rate change of velocity. It is a vector quantity. when either the speed or direction or both changes for a body, it is said to accelerate.

In option a, a car is moving with constant speed in a single direction. Hence, it is not accelerating.

In option b, through car is moving with constant speed but it is moving on a curved path which means its direction is changing. Hence, it is accelerating.

In option c, the flower pot is falling through second story. It is falling under gravity. it is accelerating due to gravity.

In option d, statue in center of park is at rest. Hence, it is not accelerating.  

Thus, correct options are b and c.
