A motorcycle accelerates from rest, and both the front andrear tires roll without slipping. (a) Is the force exerted by theground on the rear tire in the forward or in the backward direction? Explain. (b) Is the force exerted by the ground on the fronttire in the forward or in the backward direction? Explain. (c) If themoment of inertia of the front tire is increased, will the motorcycle’s acceleration increase, decrease, or stay the same? Explain

Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.
