Force can change the shape / sizeof object. 3. Force can change speed of motion. 4.Force can change the direction of motion. Necessary thing required to apply force is Frictional force.--------------------Friction force opposes the RELATIVE motion of object on the surface.Friction provides the necessary grip to hold the objects, to move the objects, to stop the motion of object.Without friction Force, we can't imagine to apply force. |
