Acceleration is a vector that has SI units of meters/second2
There is no special name for the magnitude of acceleration
(like “speed” was for velocity)
Acceleration is the change of velocity in time.
Notice the units can be thought of as (meters/second)/second
Velocity can change by...
2. changing direction only
3. changing both speed and direction
Accelerations will occur in all three of those cases
