Describes the location of an object
What is position?
Combination of all of the forces acting on an object
What is net force?
This is referred to as free fall
Measure of how much force is acting on a given area

What is forward and downward motion?
The SI unit for pressure
What is a pascal?
On a speed time graph, this represents a constant speed
What is a horizontal line?
This is speed + direction

what is BF>W
The type of graph you would use when comparing portions
What is a pie graph?
This is a quantity that has both size and direction
What is a vector?
These types of forces will NOT cause a change in the motion of a moving object.
What are balanced forces?
Gravity pulls but does NOT push, this is referred to as an....
What is an attractive force?
States that the buoyant force acting on an object in a fluid is an upward force equal to the weight of fluid that the object displaces.
