Work(W) energy to or from an object or energy from one type to another by means of a force acting on the object. The of an object enables it to do work. For example, if you lift a box 3 meters into the air, the work you perform on the box is transformed into the potential energy of the of the box. If you push a cart across the floor, the work you perform on the cart is transferred into energy due to the of the cart.

Work(W) transfers energy to or from an object or converts energy from one type to another by means of a force acting on the object. The mechanical energy of an object enables it to do work. For example, if you lift a box 3 meters into the air, the work you perform on the box is transformed into the gravitational potential energy of the position of the box. If you push a cart across the floor, the work you perform on the cart is transferred into kinetic energy due to the motion of the cart.

Explanation:

The concepts involved in this question are:

- Work: the work is defined as the energy that an object is able to transfer to another object, or the energy that is converted from one type to another.

- Gravitational potential energy: it is the energy possessed by an object due to its height, it is given by

where

m is the mass of the object

g is the acceleration due to gravity

h is the height of the object relative to the ground

- KInetic energy: it is the energy possessed by an object due to its motion, it is given by

where v is the speed of the object.

Therefore, work is done when:

- Whenever some energy is converted from GPE into KE or the other way around

- Whenever an object is pushed/lifted, so that we transfer part of our energy into the KE or the GPE of the object
