Energy

Welcome to class.

Anything that is capable of doing work has energy. A person pushing a car along a road is doing work on the car. The person is said to possess energy which he exercises by making the car move some distance.

Also, just like a student running around the school field has energy. He or She is capable of moving his weight some distance. A footballer player, a farm labourer, a palm wine tapper climbing a palm tree and a mango tree all possess energy.

Both work and energy are measured in the same unit, the joule.
