Laws
100
  • This is a push or pull acting on an object

What is force 

100
  •  This type of friction occurs when an object is sliding over a surface

  •  What is sliding friction?

100

This law states that force equals mass times acceleration

What is Newton’s second law?

200
  •  This force always pulls objects toward the center of the Earth.

What is gravitational force ?

200
  • : This force prevents motion from starting between two surfaces at rest

  •  What is static friction?

200
  • This law states that an object at rest stays at rest unless acted on by a force

What is Newton’s 1 st law ?

300
  • This is the unit used to measure force.

What is Newton

300

 This force helps you walk without slipping


What is friction?

300
  • This equation represents Newton’s Second Law

What is F = MA

400
  • This force acts in a direction opposite to motion when objects rub together

What is frictional force?

400

Helps us walk, write , drive and paddle a boat 

What is helpful friction

400
  • This law states that every action has an equal and opposite reactio

What is Newton’s third law 

500

Can make us slip, cause wear and tear 

What is unhelpful friction 

500
  •  This factor increases friction between two surfaces

 What is increased surface roughness

500
  • When you push a wall, the wall pushes back with this kind of force

What is Newton’s 3rd law ?
