To push a 25 kg crate up a 27° inclined plane, a worker exerts a force of 120 N, parallel to the incline. As the crate slides 3.6 m, how much is the work done by the worker and by the force of gravity?

Consider the motion of ball down an inclined plane and determine at which position will it have maximum kinetic energy?

Among the following options which is /are the examples of the potential energy

1. The chemical energy of a molecule

2. A space system orbiting a planet

3. A boy running on the road

4. A ball moving down an inclined plane

What will be the potential energy of marble after its halfway rolling on an inclined plane?

1. It will be greater than its kinetic energy

2. It will be equal to its kinetic energy

3. It will be less than its kinetic energy

4. None of these
