Journal Entry 12/14

The bus is accelerating at +1 m/s2, which means that its velocity (change in position over a time interval) is increasing by +1 m every second. I know this because I know that acceleration is the change in velocity over a time interval.

If the bus accelerates from the intersection at +1 m/s2, it will be 15 m from the intersection after 5.0 seconds. I know this because due to the acceleration, the change in the velocity is increasing by 1 m each second. Over the first second, the bus moves 1 m. Then over the second second, the bus moves 2 m. Over the third second, the bus moves 3 m. This continues for 5 seconds. These distances add up to 15 m.
