  1. What is power?

  2. Rate at which work is done • Example: the greater a car’s engine power, the faster the engine can accelerate the car

  3. How do we calculate power?

  4. Power = work OR….. Power = force x distance time time Power = Watts (W) Time = seconds (s) Force = Newtons (N) Distance = meters (m)

  5. A tow truck exerts a force of 11000N to pull a car. It moves the car 5m in 25 seconds. What is the power of the tow truck? Power = force x distance time Power = (11000N)(5m) 25 sec Power = 2200W
