Newton’s 2nd law relates force to acceleration. In the angular version of Newton’s 2nd law, torque τ takes the place of force and rotational inertia takes the place of mass. When the rotational inertia of an object is constant, the angular acceleration is proportional to torque.

How does torque relate to acceleration?

In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That’s because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.

What is the relationship between torque and angular acceleration quizlet?

Angular acceleration is directly proportional to the net torque and inversely proportional to the moment of inertia.
