Asked by AYDXN
A group of extraterrestrial athletes travel from the Moon to Earth to train.
How would the amount of force they exert to move change on Earth?
(1 point)
• The force needed would be less, so they would perform at a higher level.
• The force would need to be greater, so they would not perform as well.
• The force would be the same.
The force needed to move on the Earth is less than the force needed to move on the moon.

Answer: The force would need to be greater, so they would not perform as well.
Reason: Mass doesn't change, but weight = mg does. Earth's gravity (~6× Moon's) makes their weight much larger, so muscles must exert larger forces to support and lift their bodies and to accelerate vertically. (They would have greater traction from the larger normal force, but overall the muscular effort required on Earth is higher than on the Moon.)
