Acceleration
What words mean “the speed at a moment in time”?
Instantaneous Speed

Acceleration
How did you measure “instantaneous speed”?
Pass an object through a light gate attached to a timer.
Then
“instantaneous speed = object length / time to cut beam”

Acceleration
What equation did we come up with for acceleration “a” ?
a = (v – u) / t
