Energy and work are important ideas in physics, and we see them in our daily lives.
Energy is the ability to do work. It comes in different forms, such as:
When we talk about work in physics, we mean how energy moves when a force is used to move something. The formula for work is pretty straightforward:
Work = Force × Distance × cos(θ)
Here, θ is the angle between the force and the direction of movement.
Whenever we do work on an object, we are either adding energy to it or taking energy away from it. For instance, when you lift a ball, you give it potential energy. When you throw it, you give it kinetic energy.
Understanding how energy moves and changes helps us see how things work in our world!
