What Is Work in Physics?

In physics, work is a way to describe what happens when a force makes something move.

You can figure out work by using this simple formula:

$$\text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta)$$

Let’s break this down:

• Force is how hard something is pushed or pulled. It's measured in newtons (N).
• Distance is how far the object moves. It's measured in meters (m).
• $\theta$ is the angle between the force and the way the object is moving.

Why Work Matters:

• Understanding Energy Transfer: Work helps us see how energy moves from one place to another.

• Everyday Examples: Imagine you’re lifting a box. If you lift it 2 meters using a force of 10 N, the work you do is:

$$10 \, \text{N} \times 2 \, \text{m} = 20 \, \text{J}$$

That's 20 joules of work!

In short, work is key to understanding energy and how things move!
