We learned about how velocity can change.
Velocity can change by:
1) Speeding up
2) Slowing down
3) Changing direction
We can think of acceleration almost like pushing and pulling.
We decided to call the thing that changes velocity -- acceleration.
Average Acceleration
\( \vec{a}_{avg} ~ = \frac{\Delta \vec{v} }{\Delta t} ~ =~ \frac{\vec{v}_f - \vec{v}_i}{t_f - t_i} ~~~~~~~ [\frac{m}{s^2}] \)
