Project #1
Create a simple animation/simulation of a ball bouncing off of walls.
- the user
- define the size a rectangular enclosed space (4 walls)
- define the size of a ball (radius)
- define the ball's starting location (x,y coordinates)
- define the ball's starting vector (speed and direction)
- the animation/simulation
- the angle of incidence = the angle of reflection
- the speed does not change (no air resistance, etc.)
- clicking in the graphics window stops the program
- What about
- controlling the animation speed by defining the frames-per-second (FPS)?
- a wall's length should not be less than 2x the ball's diameter?
Note: Gravity is approximately 9.8 meters per second squared (m/s2) or 32 feet per second squared (ft/s2) at the Earth's surface.
Something to Think About
To simplify the calculations, assume the ball is infinitely small and has no radius. After this design/code is working, can you take into account the ball's radius?
Project #2
Let the user define up to 8 straight walls of various sizes and orientations. The walls define a closed space with no openings. Simulate A bouncing ball.
Project #3
Drop the ball onto the floor from a given height (with no air resistance). Animate/simulate a bouncing ball in earth's gravity. Assume it losses of 2% of its speed with each bounce.
Let the user
- define a height above the floor
- select the size of the ball

Planet's Gravity
The following are the g-force (gravity) you would experience on another planet if you were standing on the surface or, in the case of the ice giants, floating in the atmosphere.
| Planet | Fraction of Earth's g-force |
|---|---|
| Mercury | 0.38 g |
| Venus | 0.9 g |
| Earth | 1 g |
| Moon | 0.17 g |
| Mars | 0.38 g |
| Jupiter | 2.53 g |
| Saturn | 1.07 g |
| Uranus | 0.89 g |
| Neptune | 1.14 g |
