الوصف
Forces and Motion explores gravity, friction, centrifugal force, and the underlying laws of physics that help machines work. Simple machines such as levers and pulleys, floating and sinking, springs, elastic, and flying machines are all investigated in fun, hands-on experiments that make it easy for anyone to become a rocket scientist!
