|
Scalar |
a quantity that has only magnitude, not direction |
|
|
Vector |
a quantity that has both magnitude AND direction |
|
|
Instantaneous Speed |
speed at a point in time - an example would be what a speedometer shows |
|
|
Average Speed |
the total distance traveled divided by the total time |
|
|
Reference Point |
a preceived stationary object used to determine motion of other objects relative to it |
|
|
Distance |
how far something has moved or the measurement between two points |
|
|
Displacement |
the distance AND direction of an objects change in potion from a starting point |
|
|
Velocity |
Speed in a direction, it is a vector quantity |
|
|
Acceleration |
the rate of change in velocity |
|
|
X-axis |
on a Distance vs. Time graph, it is where you would plot DISTANCE |
|
|
Y-axis |
on a Distance vs. Time graph, it is where you would plot TIME |
|
|
Calculating Speed |
Speed = Distance / Time |
|
|
Calculating Acceleration |
A = Vf - Vi / T |
|
|
Calculating Starting Speed |
Vi = Vf - (A*T) |
