Gravitational potential energy in space will always be:
Understand the Problem
The question is about gravitational potential energy in space and its possible values. Gravitational potential energy is defined as the energy an object has due to its position in a gravitational field. The convention is to set the zero point of gravitational potential energy at infinity. Therefore, at any finite distance, the gravitational potential energy is negative because work needs to be done by an external force to move an object from that point to infinity against the gravitational force.
Answer
Gravitational potential energy in space is always negative.
In space, gravitational potential energy is always negative because it is a measure of the work done by gravity.
Answer for screen readers
In space, gravitational potential energy is always negative because it is a measure of the work done by gravity.
More Information
Gravitational potential energy is negative because it represents the energy required to move an object from a point in space to a reference point (usually infinity) where the potential energy is defined as zero. Since gravity is an attractive force, it does work on the object as it moves from space to the reference point, hence the negative sign.
Tips
A common mistake is assuming gravitational potential energy can be positive in space. It's crucial to remember the reference point and the attractive nature of gravity.
