When you jump, you exert a pushing force against the ground. Gravity pulls you back down. Why can a person jump higher on the moon than on Earth?
A The gravitational force on the moon is weaker than on Earth.
B A person has less mass on the moon than on Earth.
C Pushing forces are stronger on the moon than on Earth.
D A person weighs more on the moon than on Earth.
A) The gravitational force on the moon is weaker than on Earth.
The correct answer is A) The gravitational force on the moon is weaker than on Earth.
The force of gravity on an object depends on its mass and the gravitational field it is in. The moon has less mass than the Earth, which means it has a weaker gravitational field. Therefore, the force pulling an object towards the ground is less on the moon compared to the Earth. This allows a person to exert a greater pushing force against the ground and jump higher on the moon.
The correct answer is A) The gravitational force on the moon is weaker than on Earth.
To understand why a person can jump higher on the moon than on Earth, we need to consider the concept of gravity. Gravity is the force that pulls objects towards each other. On Earth, gravity is what keeps us on the ground and gives our weight. The force of gravity is determined by the mass of the objects involved and the distance between them.
The moon has less mass than Earth, which means it has a weaker gravitational force. The gravitational force on the moon is about 1/6th of the gravitational force on Earth. This means that if you were to jump on the moon, gravity would not pull you down as strongly as it does on Earth. As a result, you would feel lighter on the moon and be able to jump higher.
Therefore, the correct answer is A) The gravitational force on the moon is weaker than on Earth.
