Forces can't be seen, but without them, nothing around us would happen! A force is a push or pull that usually causes movement. Friction is a force that opposes

Presenting facts, figures and information on forces and motion, this title covers a range of topics including gravity, magnetic forces, measuring force and velo

"Introduces the connection between force and motion and describes the effects of air resistance, mass, and gravity"--Provided by publisher.

Easy to duplicate, [these experiments] demonstrate the intended principles and encourage critical thinking.
