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

What is uniform motion ?

Give two examples of non-uniform motion.

An elecric charge in uniform motion produces

The buoyant force on a body acts in

Different points in earth are at slightly different distancesfrom the sun and hence experience different forces due to gravitation. For a rigid body, we know that if various forces act at various points in it, the resultant motion is as if a net force acts on the C.M. (centre of mass ) causing rotation around an axis thorugh the C.M. For the earth-sun system (approximating the earth as a uniform density sphere)

For a body to move in a uniform cicular motion a ____________ force is required which acts towards ____________ of the circle.

For an object to be in uniform motion no _____ is required.
