We learned 4 equations to describe motion in one dimension with constant acceleration.
These Equations are:
- Position at time is equal to initial position plus initial velocity times time, plus one half acceleration times time squared.
- Ending velocity equals initial velocity plus acceleration times time.
- Average velocity equals initial velocity plus ending velocity divided by two.
- Ending velocity when time is unknown is velocity squared equals initial velocity squared plus two times acceleration times ending position minus initial position.
***NOTE: The image for C is wrong, it should have a 2 on the bottom not a t.
Instantaneous Velocity
The Average Velocity between points x0 and x1 is equal to the instantaneous velocity at point x½
