Work and energy are important ideas in physics. They help us understand how things move and change. Let's break it down:

1. What is Work?
   Work happens when a force makes something move. You can calculate work using this simple idea:

   Work (W) = Force (F) × Distance (d) × cos(Angle)

   Here,

   • Work is measured in joules (J).
   • Force is measured in newtons (N).
   • Distance is in meters (m).
   • The angle helps us see how the force and movement are connected.

2. What is Energy?
   Energy is what allows you to do work. When you work on something, you're moving energy to it. For example, when you lift a book, you give it energy called gravitational potential energy.

3. How are they Measured?
   Both work and energy are measured in the same unit: joules (J).
   A joule is the amount of work done when a force of one newton moves something one meter in the same direction as the force.

In short, think of work as the action that moves energy, and energy as the ability to do work.
