Free Fall Motion Experiment

A physics virtual experiment of free fall motion.

PRINCIPLE

Drop a metal ball from an elevation  and then measure the time taken by the ball to reach the ground.

This experiment is to prove this equation :

g = 2h/t²

g : gravity acceleration
h : elevation
t : time

Repeat the experiment several times to get % error.

INSTRUMENT

Electromagnet generator : Give electromagnet force to the holder to hold the metal ball.

Digital timer : Measure the time taken by the ball from the start to the ground.

Switch : Suddenly cut off the electromagnet force and also start the digital timer.

Ground : Suddenly stop the timer once the ball hits it.

INSTRUCTIONS

• Click GUIDE to show guides.
• Drag ( up-down ) the ball holder to make custom elevation.
• Click the switch to begin the experiment.
• Click RESTART to repeat.
