Starting point you choose to describe the location
Reference Point
A measure of the distance an object travels per unit of time
Speed
A push or pull on an object by another that is touching
Contact Force
Amount of matter
Mass
Combination of all the forces action on an object
Net Force
Measure of the change in velocity during a period of time
Acceleration
Total distance traveled divided by the total time taken to travel that distance
Average Speed
Push or pull on an object
Force
The acceleration of an objects mass
Newton's Second Law of Motion
Forces acting on an object that combine and form a net force of zero
Balanced Forces
Rate of change of position in which the same distance is traveled each secong
Constant Speed
The speed and direction of a moving object
Velocity
The tendency of an object to resist a change in its motion
Inertia
The gravitational force exerted on an object
Weight
Force that resists the motion of 2 surfaces that are touching each other
Friction
Process of changing position
Motion
THe difference between the initial position and the final position of an object
Displacement
force that one object can apply to another object without touching
Noncontact Force
Forces acting on an object that combine and form a net force that is not zero
Unbalanced Forces
Energy resource that cannot be used up
Inexhaustible Energy Resource
An objects distance and direction from a reference point
Position
Speed at a specific instant in time
Instantaneous Speed
An attractive force that exists between all objects that have mass
Gravity
If the net force on an object is zero the motion on the object does not change
Newton's First Law of Motion
Energy resource that is replaced as fast as or faster than it is used
Renewable Energy Resource
