Slide 12 - Diapositive

§3.2 FORCES
  • 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.

Slide 14 - Diapositive

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






Common types of forces:
  • Gravity
  • Muscle force
  • Air resistance
  • Friction

Slide 16 - Vidéo

What two forces are slowing these cyclists down?

Slide 17 - Question ouverte

Why does a sled slide easier on ice than on the road?

Slide 18 - Question ouverte

Why does skating behind someone cost less energy?

Slide 19 - Question ouverte

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.
p. 92-97

Slide 20 - Diapositive

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










What kind of force is the blue arrow?
What kind of force is the red arrow?
What will happen to the box?
