Summary
Mathematical description of motion of bodies with constant acceleration a.
Freely Falling Bodies:
- Demonstration: Feather and Penny in vacuum
- a ~ 10 m/s2 in vertical direction
Projectiles - Motion in 2 dimensions
- Demonstrations: Shoot The Monkey (Most famous demo in Physics?)
Galileo’s fundamental principles
- Principle of inertia
- Principle of superposition
- Foundations for Newton’s work later
Profound consequences upon our world view
- No reason for and earth-centered view
