In Gravity for Physical Science, students have the ability to travel to virtually any planet in our solar system and experiment with the effects of gravity using soccer balls, baseballs, golf balls, a pendulum, a cannon, and much more.

In this experiment, we use realistic, high-tech photoelectric timers and a drop tower to demonstrate the acceleration of gravity. First we place a soccer ball on top of the drop tower, and then with the click of a button, the ball begins to fall. Both photoelectric timers automatically and simultaneously start counting. When the ball reaches and breaks the first beam, the counter stops counting. The time it took for the ball to fall that distance is displayed on the front of the timer. The second timer records the time it takes for the ball to hit the ground. |
