4.Newton laws of motion

The force that opposes the motion of the object is a resistive force called ...............

Newton’s first law : Until an unbalanced force is applied on it, bodies at rest remain .....................and bodies in motion continue to move at uniform velocities

Newton’s second law : The acceleration of a body is directly proportional to the ....................force acting on it, while it is inversely proportional to its mass.
