Instantaneous Velocity - velocity at a single moment in time
Slope and Motion

d (cm) |
|
Step 1 - Draw a tangent line at the time you want to find the velocity |
| d (cm) |
 |
Step 2 - Find the SLOPE of the tangent line (Slope = Velocity)
| distance (cm) |
|
|
Slope of tangent = ∆d/∆t
= Velocity @ 6 sec.
= (2.5 m - .5m)/(8.8 sec - 4 sec)
= .4 m/s
