1. What is a force? A FORCE is a push or a pull
Forces are vectors (include size and direction)
Unit = NEWTON (N)

2. Forces can cause objects to ACCELERATE

3. Types of Forces ELECTRICAL – positive and negative charges
GRAVITY – all objects with mass pull on other objects
NUCLEAR – holds atoms together
MAGNETIC – north and south
MECHANICAL – physical push or pull
FRICTION – resistance to motion when sliding

4. TENSION
Slack lining
Force that happens in an object when it is being pulled from both sides.
Examples include slack lines, Tug of War, bike chains, and suspension bridges

5. Forces caused by protons and electrons.
The objects don’t have to be touching.
Moving, pushing, and pulling electrons is how we create electricity.
Static electricity is the building up of electrons on one surface

6. Iron, Nickel and Cobalt can all be magnetic.
Sends out magnetic field and has a North and South Pole
Cutting a magnet in ½ is like cutting an earthworm in half… Each new magnet has both a North and a South

7. ELASTIC
Happens by changing the shape of the object like a spring or rubber band.
Examples include car shocks, rubber bands, springs, binder clips
