Newton first law Notes

Force-push or a pull

1. The combination of all forces acting upon each other is net force.
2. Balance Forces two forces acting upon each other that balance each other out.
3. Unbalance force when one force is larger than the other.

Newton's 1st law- an object will remain at rest or moving with a constant speed unless a force is applied.

Friction- is a force that resists sliding between two touching surfaces through air or water.

1. Friction slows objects down.

• 3 Types of Friction:

1. Static friction- friction that prevents an object from moving
2. Sliding friction- friction due to roughness between two objects
3. Rolling Friction- Friction between the ground and the wheel.
