|
Motion
|
An objects change in position relative to a reference point.
|
|
Speed
|
The distance traveled divided by the time interval during which the motion occurred.
|
|
Velocity
|
The speed of an object in a particular direction.
|
|
Acceleration
|
The rate at which velocity changes over time; an object accelerates if its speed, direction or both change.
|
|
Force
|
A push or a pull exterted on an object in order to change the motion of the object; force has size and direction.
|
|
How do you calculate average speed?
|
Total Distance / Total Time
|
|
How do you calculate average acceleration?
|
(Final Velocity - Starting Velocity)
____________________________
Time it takes to change velocity
|
|
Net Force
|
The combination of all of the forces acting on an object.
|
|
Balanced Force
|
When the forceson an object produce a net force of 0 N.
|
|
Unbalanced Force
|
When the net force on an object is not 0 N.
|
|
Newton
|
The SI unit for force (symbol, N)
1N = 1 kg * m / s^2
|
|
Friction
|
A force that opposes motion between two surfaces that are in contact
|
|
Kinetic (friction)
|
Friction between moving surfaces
|
|
Static (friction)
|
When a force is applied to an object but doesn't cause the object to move.
|
|
Gravity
|
A force of attraction between ovjects that is due to their masses.
