Acceleration is the rate of change of velocity (a = Δv/Δt). The unit for acceleration is m/s/s, or m/s^2. Acceleration is a vector with magnitude and direction. If velocity and acceleration point the same direction, the object is speeding up. If velocity and acceleration point opposite directions, the object is slowing down. Changing direction is also a form of acceleration.
Sections:
00:00 - Visualizing acceleration (Who wins the race?)
01:11 - What is acceleration?
02:54 - Acceleration can be tricky!
04:21 - Oil drop diagram and acceleration direction
07:40 - Acceleration when velocity is constant?
08:40 - Acceleration when speed is constant?
