Measures the direction and distance between the end position and starting position
|
Displacement
|
|
|
The rate of motion Distance travel per unit time
|
Speed
|
|
|
Speed that does not change
|
Constant Speed
|
|
|
Speed in a given direction
|
Velocity
|
|
|
A change in velocity: A change in speed or a change in direction
|
Acceleration
|
|
|
The tendency of an object at rest to remain at rest, and of an object in motion to remain in motion unless acted upon by a force
|
Inertia
|
|
|
The attraction between two masses, such as the Earth and an object on its surface
|
Gravity
|
|
|
A force that resists the motion of an object. Friction results from the close interaction between two surfaces that are sliding across each other
|
Friction
|
|
|
An object that is not moving
|
At rest
|
|
|
that which can cause a change of velocity (in speed or direction) A push or pull
|
Force
|
|
|
Occurs when the net force on an object equals zero and the object's motion does not change as a result
|
Balanced forces
|
|
|
Occurs when the net force on object does not equal zero, resulting in a change in the motion of the object
|
Unbalanced forces
|
|
|
The sum of all of the forces acting on an object
|
Net force
