Which best identifies the requirements for work to be performed?

Question

an object that has a force acting on it
an object that is moving and has no net force
a force acting on a motionless object
a force that moves an object

Answer 1

The option that best identifies the requirements for work to be performed is:

a force that moves an object

This is because, in physics, work is defined as the product of the force applied to an object and the distance over which that force is applied, in the direction of the force. If a force acts on an object but does not result in movement, then no work is done.
