Answer 1

Explanation:

When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia.

This relation can be thought of as Newton’s Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force.

Angular motion obeys Newton’s First Law. If no outside forces act on an object, an object in motion remains in motion and an object at rest remains at rest

Key Points

When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia.

This relation can be thought of as Newton’s Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force.

Angular motion obeys Newton’s First Law. If no outside forces act on an object, an object in motion remains in motion and an object at rest remains at rest.

Key Terms

angular acceleration: The rate of change of angular velocity, often represented by α.

torque: A rotational or twisting effect of a force; (SI unit newton-meter or Nm; imperial unit foot-pound or ft-lb)

rotational inertia: The tendency of a rotating object to remain rotating unless a torque is
