What is a Force?
A force is a push or pull that can make things move, stop, speed up, slow down, or change direction.
Types of Forces
- Gravity: Pulls things toward Earth
- Friction: Slows things down when surfaces rub together
- Air resistance: Slows things moving through air
- Magnetic force: Attracts or repels magnetic materials
Forces are Measured in Newtons (N)
We use a spring balance (Newton meter) to measure forces.
