Provides definitions, examples, and formulas for acceleration.

Given diagrams or scenarios, students will measure and graph changes in motion.

Students are introduced to the concepts of force, inertia, and Newton's first law of motion: objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force.This instructional activity is the...

The necessity of gravitation to a circular orbit is discussed and equations for the orbital speed are derived from the law of universal gravitation. Binary systems in which two objects orbit about a center of mass are explained and...
