a quantity without direction
Example: Speed 


Term

Definition
a quantity with magnitude and direction
Example: Velocity 


Term

Definition
the vector quantity whose magnitude represents the shortest distance between the initial and final points, and whose direction points from the initial point to the final point 


Term

Definition
Total distance traveled divided by the change in time. 


Term

Definition
displacement divided by the change in time 


Term

Definition
The change in velocity divided by the change in time 


Term

Definition
the rate of change of displacement 


Term
Instantaneous Acceleration 

Definition
the rate of change of velocity 


Term

Definition
An idealized motion in which air resistance is neglected and acceleration is nearly constant. This acceleration is due to gravity and taken to be 9.80 m/s2 at the earth's surface 


Term

Definition
The push or pull required to change the state of motion of an object as defined by Newton's second law 


Term

Definition
A quantitative measure of inertia 


Term

Definition
a vector diagram that represents all of the forces acting on an object 


Term

Definition
the natural tendency of an object to remain at rest or in uniform motion at constant speed in a straight line 


Term

Definition
the force of attraction that every particle of mass in the universe exerts on every other particle 


Term

Definition
the gravitational force exerted by the earth on an object 


Term

Definition
one component of the force that a surface exerts on an object with which it is in contact 


Term

Definition
the force that an object encounters when it moves or attempts to move along a surface 


Term

Definition
the tendency of a rope (or similar object) to be pulled apart due to the forces that are applied at either end 


Term

Definition
the state an object is in if it has zero acceleration. 


Term

Definition
The force that an object exerts on the platform of a scale. 


Term
Newton's First Law of Forces 

Definition
An object at rest or in a state of motion at a constant speed along a straight line tends to stay at rest.
The sum of the forces equals 0 


Term
Newton's Second Law of Forces 

Definition
Force equals mass times acceleration 


Term
Newton's Third Law of Forces 

Definition
For every force, there exists an equal and opposite force
