A ball is thrown vertically upwards with a certain velocity. Then

When a ball is thrown vertically upwards, at the maximum height

A ball is thrown vertically upwards. Assuming the air resistance to be constant and considerable,

A ball is thrown vertically upward. What is the magnitude of velocity at the highest point ?

A ball is thrown vertically upward. What is the magnitude of velocity at the highest point ?

A ball is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy when it reaches the maximum height ?

(a) What do you understand by the kinetic energy of a body ? (b) A body is thrown vertically upwards. Its velocity goes on decreasing. What happens to its kinetic energy as its velocity becomes zero ? (c) A horse and a dog are running with the same speed. If the weight of the horse is ten times that of the dog, what is the ratio of their kinetic energies ?

A body is thrown vertically upwards. Its velocity goes on decreasing. Write the change in kinetic energy when its velocity is zero.
