Motion and Speed
Something that describes the location of an object
What is position?
Any material that can flow and takes the shape of its container
What is a fluid?
A push or pull
What is a force?
Force of attraction between objects due to their masses
What is gravity?
A quantity that has both size and direction
What is a vector?
A location to which you compare other locations
What is a reference point?
A measure of how much force is acting on a given area
What is pressure?
Units used to express force
What is the Newton (N)?
Earth's gravity is called...
What is an attractive force?
The rate at which velocity changes

What is the Pascal (Pa)?
Combination of all the forces acting on an object
What is a net force?
A force and depends on mass
What is weight?
The tendency of all objects to resist a change in motion
What is inertia?
The measure of how far something moves in a given amount of time
What is speed?
Upward force that fluids exert on all matter

What is air resistance?
Relates gravitational force, mass, and distance
What is the law of universal gravitation?
Speed in a specific direction
What is velocity?
States that the buoyant force acting on an object in a fluid is an upward force equal to the weight of the fluid that the object displaces
What is Archimedes' principle?
Won't have a net force that's 0N and produce a change in the object's motion, which could be a change in its speed or direction or both
What is an unbalanced force?
When gravity is pulling down and no other forces are acting on an object
What is free fall?
Related to its ability to sink or float
What is density?
