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.
The Average Velocity between points x0 and x1 is equal to the instantaneous velocity at point x½
