In this experiment my partner and I used a door and a Styrofoam ball, a golf ball and a marble. We tested each ball three times. The Styrofoam one we tested first it was the slowest but 2/3 times it was really accurate. Next we tested the golf ball which was the fastest 2/3 times it wasn't that accurate but once it went in a straight line. And last we tested the marble it was least accurate but also the smallest the first few trail runs it ran of the sheet before it even touched the door.
The angle at which the wave hits and object the same angle it will bounce off. If for example it hit a wall diagonally it will bounce off diagonally just the other side, if it his the wall at a straight angle it would most probably come back straight. Speed and density affects the route of the ball. A wave a bounces off a surface it cannot pass. It does this by transferring it's energy to the surface and then the surface transfers the energy back, some of the energy is lost and that's why the energy stops.

Well explained, but define accurate. As a reader, I'm not really sure what accurate means in this experiment. Remember to explain what happened.
