Free Fall

Free fall is a type of motion that we see in daily life, for instance when we drop an object or jump down from something. In both cases, the only thing that pulls the object towards the earth is gravity; nothing else is pushing or pulling the object. Gravity is dependent upon both the mass and size of the planet, and will therefore change for each planet. Essentially it is what keeps us from floating away into space!

In this experiment you can experience free fall motion on different planets. By comparing the velocity and free fall time of the falling object, you can measure the gravitational acceleration and check the effect of mass on free fall motion.

At anytime during the experiment you can test your knowledge by answering a series of questions. They are also a good tool to help you to understand the ideas behind the experiment better. If you have questions, be sure to check out the information page!
