1. Introductory Physics

2. How we describe motion Speed – how fast something is moving Velocity – speed and direction Acceleration – change in velocity Acceleration of Gravity – 9.8 m/s 2

3. How we describe motion Momentum – an object’s mass X velocity Force – required to change on object’s momentum Mass – amount of matter Weight – force measured by a scale, mass X gravity’s accel.

4. Free-Fall Free-fall – no resistance to slow you down Free-fall leads to being weightless Astronauts are in a constant state of free- fall – If you move fast enough, you can fall continually

5. Newton’s Laws of Motion Newton’s First Law

6. Newton’s Laws of Motion Newton’s Second Law

7. Newton’s Laws of Motion Newton’s Second Law

8. Newton’s Laws of Motion Newton’s Third Law

9. Angular Momentum Similar to momentum, but moving in a circle L = m X v X r Angular momentum is conserved

10. ENERGY

11. Types of Energy Kinetic Energy – involves motion Radiative Energy – involves light Potential Energy – might later be converted to other forms of energy
