Playing Frisbee

Over the weekend, my sister and I played frisbee in our frontyard. In this picture, my sister is throwing the frisbee to me. As she releases the frisbee into the air, the air moving above the frisbee flows faster than the air underneath it. Due to the Bernoulli principle, the lower air pressure on top of the frisbee compared to the pressure underneath the frisbee causes the flying disk to rise.

Newton's Third Law, which states that for every action there is an equal and opposite reaction, is also shown in the movement of the frisbee. While the frisbee moves, it forces air down (action) and air forces the Frisbee upward (reaction).

Once in the air, the frisbee remains stable because of its angular momentum or spinning. Gravity also has an affect on the frisbee by accelerating its mass to the center of the earth.
