How different is the same jump on Earth and the Moon?
The same person can leave the ground in the same way, yet different gravity changes the jump. Make a prediction before seeing the result.
Start the gravity jump01
What to compare
- 01Does mass change on the Moon?
- 02What happens to a scale reading?
- 03Where does the same takeoff rise higher?
- 04How does time in the air change?
02
Are mass and weight the same thing?
Mass describes the amount of matter. Weight is the force of gravity on that mass. Mass can stay the same while weight changes when gravity changes.
- Earth gravity
- about 9.81 m/s²
- Moon gravity
- about 1.62 m/s²
- Comparison
- same takeoff speed
- Experience
- predict → change → jump

How the experience works
- 01Predict
Choose what you think will happen
- 02Set conditions
Choose mass and an Earth jump height
- 03Jump
Run the same takeoff on both worlds
- 04Compare
Look at mass, weight, height, and air time
04
Predict before you reveal the answer
The result is hidden at first. Compare your prediction with the calculation after you run the experiment.
