§3.2 - Learning Goals

• I can explain that you cannot see a force, but only the effect 
• I know different forces acting on a moving person (gravity, muscle force, air resistance and friction) 
• I can draw forces with arrows
• I can calculate with forces in Newtons.

Types of forces

A force is a push or pull. Forces cannot be seen, but their effects can.

Common types of forces:

• gravity
• muscle
• air resistance
• friction

Types of forces

• What forces are slowing a cyclist down?
• Why does a sled slide easier on ice than on the road?
• Why does skating behind someone cost less energy?

Measuring forces

Newton (N) is the unit of a force. 

The more newtons, the stronger the force.

A Newton meter can help

you measure the force.

Showing forces

We use arrows to show two things about the force:

The direction = the direction the arrow points at

The size = the length of the arrow

TB P.92-97

What kind of force is the blue arrow?

What kind of force is the red arrow?

What will happen to the box?
