A boy sitting in a moving car possesses kinetic energy.

Define kinetic energy?

An electron and a proton are possessing same amount, of kinetic energy. WHich of two has a greater De Brogile wavelength? Justify your answer.

Two masses of 1g and 9 g are moving with equal kinetic energies. The ratio of the magnitudes of their respective linear momentum is

A person sitting in a moving train throws a ball vertically upwards. How does the ball appear to move to an observer inside the train

A person sitting in a moving train throws a ball vertically upwards. How does the ball appear to move to an observer outside the train?

A boy throws a ball in air at 60^@ to the horizontal along a road with a speed of 10 m/s (36km/h). Another boy sitting in a passing by car observer the ball. Sketch the motion of the ball as observed by the boy in the car,if car has a speed of (18km/h). Give explanation to support your diagram.

Two bodies of mass m_1 andm_2(>m_1) have equal linear momentum. Which body possesses greater kinetic energy?

A glass of water is stirred and then allowed to stand until water stope moving. What has happened to kinetic energy of the moving water?

Two objects having same mass 'm' are moving with velocities v and 2v. Find ratio of their kinetic energies.
