Jump on in…Gravity Exploration
Part A: How much would you weigh on other planets and the moon?
The more mass a planet has, the more gravity it has. The mass of the Earth is
0.9742 × 1024 kg—really big. Planets which have more mass than Earth would have
more gravity than Earth. A person would weigh more on these planets than they
do on Earth. Determine your weight on the other planets by multiplying your
weight (your best guess) by the gravity on that planet. Be sure to include the unit!

Part B: How far could you jump on other planets and the moon?
Determine how far you can jump on the Earth. To do this:
○ Place a piece of tape on the floor as a starting line.
○ Jump as far as you can off of both feet.
○ Have your partner mark where you first land not
where you end up!
○ Measure the distance in cm and record in the table.
○ Do this five times, and then find the average.
○ Pick up the tape when you are finished.

Length on Earth
(average all 5
jumps)
Determine we how far you would be able to jump on the other planets by dividing your jump
length by the gravity on that planet. Be sure to remember your unit!
