7. The gravitational potential energy of the moon with respect to earth is
(a) always positive
(b) always negative
(c) can be positive or negative (d) always Zero
Answers
Answer:
b option is the answer of this question
Answer:
The correct answer is Option B: Always negative.
Explanation:
When two masses come together slowly from infinity, work is done on the system.
i.e. work must be done on a body if it is taken away from the gravitational field. Thus, we get that the potential energy is negative.
Gravitational potential energy:
The energy that an item has or acquires when its location changes as a result of being in a gravitational field are known as gravitational potential energy.
Gravitational potential energy can be defined as an energy that has a connection to gravitational force or gravity.
Gravitational field:
A gravitational field is a model used in physics to explain the effects that a large thing has on the area surrounding it, exerting a force on smaller, less massive bodies.
