If the mass of two bodies is doubled and the distance of two bodies also doubled, the new gravitational force becomes what ?

If force and length increases by 4 times, then energy becomes 16 times.

Speed of a body in motion is doubled. Its kinetic energy is now …………. Times the original kinetic energy.

How fast should a student of mass 50 kg run , so that his kinetic energy becomes 625 J ?

A particle of mass 10 g moves along a circle of radius 6.4 cm with constant tangential acceleration. What is the magnitude of this acceleration if the kinetic energy of the particle becomes equal 8xx10^(-4)J by the end of the second revolution after the beginning of the motion?

Newton's laws of motion can be applied to a block in liquid also force due to liquid (e.g. upthrust) are also considered in addition to toher forces. A small block of weight W is kept inside. The block is attached with a string connected to the bottom of the vessel. Tension in the string is W//2 Q. If weight of the block is doubled then tension in the string becomes x times and the time calculated above becomes y times then
