What do force arrows represent?

What are contact forces?

What are non-contact forces?
Non-contact forces act between two objects that are not physically touching.
What is thrust?

What is friction?
Friction is the force between two moving surfaces.
What is weight?
Weight is the force caused by gravity.
What is air resistance?

What happens when forces are balanced?
When forces are balanced, there is no change in the object.
What happens when forces are unbalanced?
When forces are unbalanced, there will be a change in the object.
What does a larger force do?
The larger the force, the faster the object will start to move.
