Term | Definition |
Force | A push or a pull on an object |
Motion | A process of changing position. |
Balanced forces | Are two forces acting in opposite directions on an object,
with a net force of 0 Newtons. |
Unbalanced forces | The net force of an object is not 0. |
Force diagram | A diagram showing all the forces acting on an object,
the force's direction and its magnitude. |
Position | An object's distance and direction from a reference point. |
Direction | The path on which something is moving or pointing. |
Speed | The distance an object moves divided by the time it takes
to move that distance. |
Average speed | The speed over an entire distance; average speed is equal to
the total distance traveled divided by the total time. |
Distance | The amount of space between two points. |
Velocity | The speed AND direction of a moving object. |
Displacement | The difference between the initial, or starting , position and
final position. |
Time | The thing that is measured as seconds, minutes, hours, days,
years, and months etc. |
Unit rate | Rates expressed as a quantity of 1; 1 mm |
Conversion factor | Converting one set of units into an equivalent expressed in another. |
Graphs | A way to analyze the relationship between two sets of
numbers. |
Distance time graph | A graph that shows how distance and time are related. |
Speed time graph | A graph that shows the speed of an object on the y-axis and time
on the x-axis. It shows how the speed of an object changes
during each interval of time. |
