When you jump, you exert a pushing force against the ground. Gravity pulls you back down. What can’t a person jump higher on the moon then on earth

A person cannot jump higher on the moon than on Earth primarily because the moon has weaker gravitational force compared to Earth. The gravitational force on the moon is about 1/6th of the gravitational force on Earth.

When you jump, you exert a pushing force against the ground to propel yourself upwards. On Earth, gravity counteracts this force, pulling you back down. The stronger gravitational force on Earth makes it more challenging for you to overcome it and jump higher.

On the moon, however, the weaker gravitational force allows you to exert the same pushing force with less resistance from gravity. Although the force you apply to jump is the same, the body experiences a weaker force pulling it down. Consequently, you would be able to reach greater heights than on Earth due to the reduced gravity on the moon.
