Question

The motion of moon around earth can be described as:

• A. free fall under gravity
• B. free fall without any gravitational force
• C. linear motion
• D. periodic motion

Answer 1

Answer: (A), (D)

The correct options are
A free fall under gravity
D periodic motion

The moon moves around earth with a velocity that is constant in magnitude yet it is a free fall under gravity because it is falling constantly but it is missing the earth. It is also a periodic motion because the moon is going around earth in a fixed orbit.
