1. Bell Work: More Acceleration
A ( tangent / curved ) line shows instantaneous speed on an x-t graph.
Average and instantaneous velocities are the same when the speed is ( constant / changing ).
When moving at a constant velocity, the acceleration = _______m/s2.
An object is accelerating when its ( distance / speed ) or ( direction / time ) is changing.

2. Today’s Goal: 1. Finish front of kinematics practice problems.
Start on the back of kinematics.
Fill in the vo vf t a x (given and unknown)
Figure out which variable is not present
Choose the equation that does not contain that variable
3. Constant Speed Lab – use conclusions as a model for the conclusions of the acceleration lab.
