|
Motion |
An objects change in postion relative to a reference point |
|
|
Force |
A push or pull exerted on an object in order to change the motion of the object; force has size and direction. (scalar) |
|
|
Gravity |
A force of attraction between objects that is due to their masses |
|
|
Constant Velocity |
A constant, unchanging motion in a constant direction; in other words an object is traveling the same distance in the same direction every second. (Vector) |
|
|
Speed |
The distance traveled divided by the time interval in which the motion occured. |
|
|
Newton |
The SI unit for force symbol N. |
|
|
Weight |
A measure of the gravitational force exerted on an object; its value can change with an objects location in the universe |
|
|
Resultant Velocity |
The outcome of the addition of two velocity vectors; in any situation not dealing with velocity the same value would be called a resultant vector. |
|
|
Velocity |
The speed of an object in a particular direction. |
|
|
Net Force |
The combination of all of the forces acting on an object. |
|
|
Mass |
A measure in the amount of matter in an object. |
|
|
Acceleration |
The rate at which velocity changes over time; an object accelerates if it changes in speed, direction, or both. |
|
|
Friction |
A force that opposes motion between two surfaces that are in contact. |
|
|
Reference point |
A point in relation to which other measurements such as size, motion, and speed are made. |
