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 then on earth a. pushing forces are stronger on the moon then on earth b. the gravitational force on the moon is weaker than on earth c. A person has less mass on the moon and earth d. A person weighs more on the moon, then on earth.
The correct answer is b. the gravitational force on the moon is weaker than on earth.
On the moon, the gravitational force is about 1/6th of what it is on Earth. When jumping, the upward force or the pushing force against the ground remains relatively the same on both the moon and the Earth, but the gravitational force pulling the person back down is much weaker on the moon. This results in the person being able to jump higher on the moon compared to on Earth.
b. the gravitational force on the moon is weaker than on earth.
On the moon, gravity is only approximately one-sixth as strong as it is on Earth. This means that the gravitational force pulling a person down is much weaker on the moon, allowing them to jump higher. When jumping, the upward force produced by pushing against the ground can overcome the weaker gravitational force, resulting in a higher jump.
The correct answer is b. 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, let's break down the factors involved:
1. Pushing Force: When you jump, you exert a pushing force against the ground, propelling yourself upwards. This force depends on your leg muscles and the amount of force you can generate.
2. Gravitational Force: Gravity is the force that pulls everything towards the center of the Earth. It is determined by the mass of the objects involved. On Earth, gravity is relatively strong due to the large mass of the planet.
Now, considering these factors, let's analyze the options:
a. pushing forces are stronger on the moon than on Earth: This statement is incorrect. The strength of the pushing force is determined by the person's muscles, which is not affected by the location (Earth or Moon) itself.
b. the gravitational force on the moon is weaker than on Earth: This is the correct answer. The Moon has a smaller mass compared to Earth, which results in a weaker gravitational force. Therefore, a person can overcome this weaker gravitational force more easily when jumping on the Moon.
c. A person has less mass on the Moon than on Earth: This option is incorrect. The mass of a person remains the same regardless of location.
d. A person weighs more on the Moon than on Earth: This option is incorrect. Weight is determined by the gravitational force acting on an object. Since the gravitational force on the Moon is weaker, a person would weigh less on the Moon compared to Earth.
In summary, a person can jump higher on the Moon than on Earth because the gravitational force on the Moon is weaker than on Earth.
