UNIT OVERVIEW

Forces are everywhere. When you kick a ball, open a door, or feel yourself pulled down when you jump, you are experiencing forces.

In this unit, you will learn:

• What a force is and what forces can do
• The difference between contact forces and non-contact forces
• How gravity, weight, and mass are connected
• How magnetic and electrostatic forces work
• A simple scientific explanation of lightning

By the end of this unit, you will be able to identify different types of forces, calculate weight using a formula, and explain everyday events using force concepts.
