A motorcycle has less power than a truck, but it starts faster than a truck. Why?
The motorcycle is smaller than the truck, but the quality is much smaller than the truck, so the motorcycle starts quicklyThe key is to consider the quality of experimental data from the above is not difficult to see that the important factors of quality but also affect the car starting speed, the greater the quality, start more slowly. So although the truck than a motorcycle driving motorcycle, but the quality is much smaller than the truck, so starting soon.
The truck is heavy and the tyres are so heavy that his traction needs to overcome a lot of resistanceMotorcycle light friction is also small
