Scratch

In this fun game your goal is to keep the balls balanced on your board. Score is added up depending on the weight of your balls and how long they are on the board.

Instructions:
Click to drop the ball. Hold your mouse down to increase its size.
Keep the board balanced! Score will not be added if there are no balls on it, so keep adding them.

The Physics behind this:
This project uses torque and gravitation forces to simulate what would happen in real life.
The balls move according to MGcos0. Mass is your weight, with it being in KG. Starting weight is .1 KG. G is Gravity, or 9.8 meters/sec^2. I converted this to .98 units on the grid. 0 is theta, or the degree of the board.
The board rotates using torque. Torque is the cross product of force and distance, or FxD. Unfortuantly, this project assumes that the force is always at right angles with the distance, as it takes complicated rotary motion and related rates to fix it. I then added up all of the torques from each ball, and then changed the angle by it.

Please love-it!
