- 2. Acceleration ● Acceleration is the change in velocity with time. ● Remember that velocity is a vector and is essentially speed in a given direction. ● Signs of acceleration ○ Speeding up ○ Slowing down ○ Change in direction ● A constant non-zero acceleration does NOT mean the object is staying at the same velocity. ● A constant non-zero acceleration means that the object is speeding up, slowing down or changing direction at a constant rate, but it is still changing. ● The units are usually m/s2 or m/s/s...that means that the velocity is changing a certain number of meters per second for every second.
