Question:
Why does a car go down on the rear axle when it accelerates from stationary?



Replies:
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.
