In which of the following scenarios is work being done, according to the physics definition?

The "power" of a machine measures...

An object lifted 10m gains 200 J of potential energy. If the same object is lifted 20m, its potential energy gain is...

It takes 60 J of work to push a large box 6 m across a floor. Assuming the push is in the same direction as the displacement, what is the magnitude of the force on the box?

If you do work on an object in one third of the usual time, your power output is...

A 5 kg mass has 100 J of potential energy with respect to the ground. Approximately how high above the ground is the mass?

A bow is drawn so that it has 40 J of potential energy. When released, the arrow will theoretically have a kinetic energy that is

If you do 200 J of work in 10 seconds, your power output is...
