... Mass and Acceleration • If you throw a softball and a baseball as hard as you can, why don’t they have the same speed? • The difference is due to their masses. • If it takes the same amount of time to throw both balls, the softball would have less. • Force, mass, acceleration and acceleration are r ...

... Once motion between the contacting objects takes place, the frictional force become a kinetic one. The kinetic frictional force between two objects is smaller than the maximum static frictional force. The magnitude of the frictional force depends on the normal force, and on a coefficient of friction ...
