Acceleration

• Acceleration is the rate of change of velocity over time.
• a = delta(v)/delta(t)
• Why this is interesting is that a lot of games (and real world activities) care about acceleration.
• Of course you also care about velocity.
• Driving is a lot about acceleration (the gas pedal is called the accelerator).
• Flying is too, and for that matter so is football.
• Of course acceleration and velocity are often affected by things like wind resistance, but you can often ignore it.
• You can get distance travelled by calculating area under the velocity curve.
