Suppose a body is kept on frictionless surface(but gravity os there). If we give a little push to the body , will it continue in state of motion with constant velocity or not..?….if yes then why…?
If the surfaces are totally frictionless theñ on giving a slight push it would be put to motion with uniform velocity. Newtons first kaw is the reason. Since there is no net force acts, velocity should remain constant.
The force due to grsvity acts vrtically downwards and os canceled by the normal reaction
