A push or pull on an object
A stop on an object
The start of an object
What can force do to an object?

Slow down an object
Have the object remain in place
Have the object change shape
All of the above
What is the measure of force?

force
speed
friction
mass
The girls in this picture represent ________ forces (or 2 objects in equilibrium).
Balanced Force
When forces are balanced, there is no change in motion
When two forces act upon each other in opposite directions, and they are both the same size.
Equal in size and opposite in direction
Occurs when objects change in motion and can happen in two different ways.

Which boy will have an easier time getting down the hill?
Boy A , because he is experiencing less friction than boy B.
Boy B, because he is experiencing more friction than boy A.
How does the mass of an object affect it's motion?
It has no effect
The less the mass the less effect a force will have
The greater the mass the greater the effect a force will have
The greater the mass the less effect a force will have
