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 jump

01

What to compare

  1. 01Does mass change on the Moon?
  2. 02What happens to a scale reading?
  3. 03Where does the same takeoff rise higher?
  4. 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

  1. 01
    Predict

    Choose what you think will happen

  2. 02
    Set conditions

    Choose mass and an Earth jump height

  3. 03
    Jump

    Run the same takeoff on both worlds

  4. 04
    Compare

    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.
