While in Cambodia, I got to ride all different types of scooters and motorcycles. All over people, you'll find people getting around using motorcycles and mopeds. Motorcycles include different parts of physics because you deal with dynamics, acceleration, and gravitational force. Trying to keep your body centered to prevent from an accident, while the motorcycle accelerates all has to do with physics. Not only that, but when turning a motorcycle, the bike must lean without falling totally over. The faster you turn, the more lean there is needed to complete the turn. A really lean turn is generated by centrifugal force, which can we compared to turn of gravitational force.
