Physics: Forces at Work (13:15)This Science Screen Report explains the forces that come into play when a cyclist puts on the breaks, a pitcher throws a curve, and an airplane takes to the sky. Focusing on such concepts as acceleration, terminal velocity, friction, and balanced and unbalanced forces, the program also delineates Newton’s laws of motion and Bernoulli’s principle of pressurized air and fluid behavior.

Principles and Laws of Motion (18:18)To study and understand the motion of objects in space, students need to build a foundation of knowledge in a wide variety of physical science phenomena. This program demonstrates typical mechanics situations common to many physics courses, such as circular motion, projectile motion, straight line motion, and inclined plane motion. (18 minutes)
Gravitation (29:16)Although gravity is the weakest of the fundamental forces, it is nevertheless the most universal—and the easiest to demonstrate! This program demystifies the properties and behavior of gravity with the help of real-world illustrations and animated graphics.
