	Whelmer #22: Energy Transfer
		A ping pong ball bounces 10 to 15 feet high using energy transferred from a golf ball.
		After the initial drop of the ping pong ball, ask students how the ball can be made to bounce higher (throw the ball down, drop it from a higher point, etc.).
		The mass of the golf ball is much greater than the mass of the ping pong ball.

		As the ball is thrown from the tube, the ball rubs against the sand paper on the side of the tube from the direction the tube is moving.
		Friction from the sand paper on the ping pong ball causes it to spin rapidly in a clockwise direction for right-handed throws and counterclockwise for left handed throws.
		As the ball spins, the surface friction of the ball with the surrounding air drags a thin layer of air with it.

		A series of experiments, some involving over half a million ping-pong balls and a ski slope, are helping scientists understand the complex physics underlying the most devastating type of mountain disaster - powder snow avalanches.
		However, the ping-pong ball tests enabled the researchers to develop mathematical models that could describe the behaviour of powder snow avalanches.
		These instruments allowed the researchers to track the movement of individual ping-pong balls and measure their velocity.

		Lift is caused by air moving faster over one side of a ball or wing than it moves over the other side.
		The lift is such that the ball or wing moves toward the side with the fastest moving air.
