Document Summary
When a ball hits a paddle or brick in breakout, how does it behave? a. i. 1. a. www. roundgames. com/game/xenocreate+2 a. ii. Why does it react the way it does? a. iv. How does it react differently if it hits in the middle of the paddle vs. the edge of the paddle? a. iv. 1. a. iv. 2. If it hit the middle of the paddle, it would be almost at a right angle. a. iv. 3. The angle of incidence didn"t have any effect on the angle of reflection. a. v. Why does the ball behave like this? a. vi. a. vii. Is this an accurate portrayal of the world? a. vii. 1. a. vii. 2. a. vii. 3. The collision had constant velocity the entire time. There"s eternal force, never runs out of gas, no friction. If you hit it off the corner of the paddle, you get it going a lot faster for some reason? a. vii. 3. a. Maybe because the y velocity is kept constant. Very hard to hit the angle of reflection as being straight.
