Bodies of larger mass need ____ iniital effort to put them in motion.

Fill in the blanks: Mass of a body is __________ of inertia of the body to ________ motion.

Two solid spheres of same mass are made of metals of different densities. Which one of them has a larger moment of inertia about a diameter?

Two bodies of unequal mass are moving in the same direction with equal kinetic energy. The two bodies are brought to rest by applying retarding force of same magntiude. How would the distance moved by them before coming to rest compare?

A body in motion will remain in ____________ if balanced force acts on it.(Uniform motion/Retardation).

Two sphere are of same mass and same external radius, one is solid and the other is hollow. Which one of them has larger moment of inertia about its diameter?

A body of mass M at rest is struck by a moving body of mass m.Prove that the fraction of the initial kinetic energy of mass transformed to the struck body is (4Mm)/((m+M)^2).

Separation of Motion of a system of particles into motion of the centre of mass and motion about the centre of mass :- Show (dL')/(dt)=(sumr_i') xx (dp')/(dt) Further, show that (dL')/(dt)= tau'_(ext) where tau'_(ext) is the sum of all external torques acting on the system about the centre of mass.
