Session 1: Types of forces

Any push or pull is called...

• gravity.

• magnetism.

• a force.

• acceleration.

Friction would be an example of ...

• gravity.

• magnetism.

• contact force.

• non contact force.

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed

What is the SI unit used to measure force? 

• Pounds 
• Grams 
• Newtons 
• kg/ m²

A non-contact force is between

• two objects that aren't touching

• two objects that are touching

• the ground and wheels

• a boy sitting on a chair

Look at the pictures. Read the scale on each newton meter.

• 6 N

  10 N

• 5 N

  8 N

• 4 N

  7 N

• None of these
