Car Pitch and Acceleration
Country: United Kingdom
Date: Summer 2013
Why does a car go down on the rear axle when it accelerates from stationary?
Because more of the car's weight is on the rear wheels when it's accelerating.
Think of a bicycle doing a wheelie. The force between the wheel and the street
is horizontal, so the force vector cannot go through the center of mass, so the
force must include a torque about the center of mass.
