The total work done in moving a body also along closed part in a gravitational field is always equal to?
Answer: zero
Explanation
The total work done in moving a body along a closed path in a gravitational field is always zero.
This is because the gravitational field is conservative,
Meaning the work done by the conservative force is independent of the path taken and
Only depends on the initial and final positions,
And for a closed path, the initial and final positions are the same.
