How does the kinetic energy of a moving body depend on its (i) speed, and (ii) mass?
Kinetic energy is directly proportional to the mass of the body. Kinetic energy is directly proportional to the square of the speed of the body.
(a) On what factors does the gravitational potential energy of a body depend ?
(b) Give one example each of a body possessing : (i) kinetic energy, and (ii) potential energy.
How does the kinetic energy of an object change, when its (i) mass alone is doubled and (ii) speed alone is doubled?
