when work is done, energy moves from one place to another or changes form. For example, lifting a book transfers your energy to the book, giving it potential energy.

1. When you push something and it moves, the energy you use gets transferred to the object, making it move faster. This energy is called kinetic energy.


2. When you lift something, like picking up a book, you are transferring energy to it. This energy is stored as potential energy because the book is now higher up.


3. (Thermal Energy): When you slide something, friction happens. The energy you use to overcome friction gets turned into heat. For example, rubbing your hands together makes them warm.


4. Electrical Energy: In electrical gadgets, when you plug them in, electricity does work. This energy can be used to light a bulb, run a fan, or charge a battery.
