Forces And Pressure

1. Frictional Force

1.1. Allows you to walk without slipping

1.1.1. Causes a moving object to slow down or stop moving

1.1.1.1. A rougher surface produces more friction than opposed to a smoother surface

2. Pressure

2.1. = Force/Area

2.1.1. Can change the shape of objects

2.1.1.1. New node

3. Magnetic Force

3.1. Pulling and pushing force exerted by magnets

3.1.1. Pulling force is known as attraction, pushing force as repulsion

3.1.1.1. Like poles repel each other, opposites attract

3.1.1.1.1. Steel, nickel, cobalt, iron are magnetic

4. Gravitational Force

4.1. Pulling force by the Earth's gravity

4.1.1. Greater the gravitational force, heavier the object
