Question

The equal and opposite force of the Earth's Gravity pulling you down toward the ground with 10 Newtons would be the force of your body pulling __________ on the Earth with __________ of force.

A) away, 10 Newtons
B) upward, 10 Newtons
C) downward, 10 Newtons
D) sideways, 10 Newtons

Answer 1

When you stand on Earth, the force of your body pulling upward on the Earth is equal to the force of the Earth pulling you downward with the same magnitude.

Step-by-step explanation:

According to Newton's third law of motion, when you stand on Earth, the Earth exerts a force on you, pulling you toward the ground. Simultaneously, you exert an equal and opposite force on the Earth, pulling it up toward you. However, due to the Earth's much greater mass, the acceleration of the Earth toward you is negligible. Therefore, the equal and opposite force of your body pulling on the Earth with 10 Newtons would be the force of your body pulling upward on the Earth with 10 Newtons of force.
