Distance and Displacement-

Distance-

Total length of the path traveled

Displacement-

The shortest distance from start to end point that equals Zero.

to test instantaneous speed-

rador gun and speedometer

Velocity is

how fast something goes and what direction

instrument to measure instantaneous speed-

Speedometer

A point used to determine the position of an object

Reference point

How far an object has moved

Distance

The Shortest distance from start to finish

Displacement

M/S; scalar

Speed

Displacement/time; vector

Velocity

A quanity with a magnitude and a direction

Vector

The total distance traveled divided by the total time of travel

Speed

Measured in meters

Distance and Displacement

A quanity with magnitude only

Scalar

Speed at given point

instantaneous speed

includes the

Speed=

vector

what does velocity have that speed does not?

velocity has speed and direction while speed just determines how fast something goes without changing direction
