The moon's revolution around the earth involves which of the following?
The moon's revolution around the earth involves which of the following?
The correct options are
A Newton's First Law of Motion
B Centripetal Force
D Newton's Third Law of Motion
Newton's First Law of Motion states that any object at rest remains at rest and any object in motion continues the same motion (without a change in direction and speed) until and unless acted upon by an external unbalanced force. Here moon revolves around earth with same speed and is always in motion hence, Newton's first law is applicable. Also Newton's Third Law of Motion, which states that "To every action there is an equal and opposite reaction", is applicable since both the earth and the moon attract each other with the same force but since the mass of the earth is much larger compared to that of the moon, the moon experiences greater acceleration. The gravitational force is equal to the centripetal force which keeps the moon revolving around earth.
