What is a force!?
A force is a push or a pull that can change the positions,speed or state of an object
How does a force occur!.

What are the 2 different types for forces!?
Contact forces
And
Non-contact forces
What are contact forces!?
Are forces that occur when objects physically touch
What are 3 examples of a contact force!?
Friction
Air resistance
Tension
What is a normal contact force!?
When an object at rest,exerts a force on the surface it’s placed on. There is a reaction force that acts at a right-angle to the surface
Five an example of a normal contact force…..
A book on a table exerts force down on the table
And the table exerts a normal contact force on the same side back up on the book
What is a non contact force!?
Are Forces that act between objects that aren’t physically touching
