2-1 What is Force?
Objectives:

-Define Force
-Describe the nature of forces
-Explain how force is related to motion


Vocabulary:

Force- Push or pull that gives energy to an object, sometimes     causing a change in the motion of the object.

Most measurement involving motion such as velocity,                 acceleration, and momentum include direction.
-  Forces also act act in a particular direction.
-  When two forces are acting in the same direction they are added together.
-  When the total force on an object is in one direction, the force is called an unbalanced force.
-  An unbalanced force changes the motion of an object.
-  When two forces act in opposite directions, they combine by      subtraction.
-  If one force is greater than the other force, the object moves in the direction of the greater force.
-  Forces that are in opposite directions and equal in size are called  balanced forces.
-  When forces are balanced, there is no change in motion.
