1
New cards
Scalar
Has only magnitude (or size only, no direction)
2
New cards
Distance
Total length of path without regard to direction
3
New cards
Vector
A quantity that has magnitude and direction
4
New cards
Displacement
How far away from a reference point and in what direction (a vector)
5
New cards
Speed
Distance changing over time. v=d/t
6
New cards
Velocity
How displacement changes over time. v=d/t
7
New cards
Instantaneous Speed
Speed at one instant in time
8
New cards
Average Speed
Speed over a longer interval. VAvg=total distance/total time. If acceleration is constant VAvg=(V1+V2)/2
9
New cards
Slope
Represents speed. To find speed, calculate slope
