Investigating Motion

Average speed

the total distance traveled divided by the total time to travel that distance

Displacement

the difference between the final & initial positions of an object

Distance

a numerical measurement of how far objects or points are

Distance-time graphs

a graph that shows the comparison of distance over time

Force

a push or pull

Linear Motion

the motion of an object in only one direction

Motion

changing positions or location

Position

an object’s distance and direction from a reference point

Reference point

the starting point

Speed

a measurement of the distance an object travels in a given amount of time, direction does not matter

Time

the measurable period during which something takes place

Vector

a quantity that has both magnitude & direction

Velocity

the directional speed of an object in motion, a vector quantity
