Types of Forces
1. Force is _a push or pull upon an object resulting from the object's interaction with another
object.
2. Force has both magnitude and direction, so it is a -_vector quantity,its units are newtons
3. Force is measured in newton 4. There are many types of forces, some of which are listed in the table below.

Name: The normal force : Symbol: N
The support force acting on an object in contact with another stable object
The normal force is perpendicular to the surfaces in contact.
Name: The tension force Symbol:T
The force transmitted through a string, rope, or cable when it is pulled tight.
Tension Force
Name: Frictional Symbol: N
