You and a friend are jumping on a trampoline. Why does Earth, which is rapidly orbiting around the sun, not move under your feet when you jump?

A. Newton's third law holds that there is an equal and opposite force exerted by the trampoline on your feet, which allows you to move with Earth through space.

B. Newton's first law holds that your body moves along with Earth because it is not compelled to change its motion by an unbalanced force.

C. Newton's second law holds that the acceleration produced by the force of gravity is offset by the force of friction on your feet.

D. There are different rules in space and on the surface of the earth

You and a friend are jumping on a trampoline. Earth, which is rapidly orbiting around the sun, not move under your feet when you jump. This is due to Newton's first law of motion which states that "until an external unbalanced force acts on an object, it will remain at rest or in motion".

So, as per first law of motion, our body moves along with Earth because it is not compelled to change its motion by an unbalanced force.

Hence, the first option is (b).
