Question

Which is correct about the moon's motion around the earth?

A. The moon is in free fall.
B. Centrifugal force acting on the moon balances the force of the earth's gravity.
C. The moon exerts no gravitational force on the earth.
D. There is no gravity acting on the moon because it is in orbit.

**I think it's either A or B but not sure which one? What do you think? Thanks:)

Answer 1

If it were A, then the moon wouldn't orbit the Earth... so I'd say B.

Answer 2

B

Answer 3

ahh okie thank you:)

Answer 4

I think is A, namely moon is free falling in the gravitational field of the earth.
More precisely, moon exerts on earth a gravitational force, and, by the third principle of mechanics, earth exerts on the moon a force with equal magnitude and direction, but opposite to that exerted by the moon

Answer 5

ohhh okay:) thanks!!

Answer 6

first if all it couldn't be A simply because the moon doest accelerate with a= 9.8m/s^2

Answer 7

thanks! @iheartfood

Answer 8

micheal what your saying is the centrifugal force and its relative for of inertia but this question is asking about the motion of the moon

Answer 9

force*
