Torque is a rotational force that causes an object to rotate around an axis. It depends on the force applied, the distance from the axis of rotation (lever arm), and the angle between the force and the lever arm. Understanding torque is crucial for solving problems involving rotational motion and equilibrium.
In AP Physics 1, torque problems often involve calculating the net torque on an object, determining the conditions for rotational equilibrium, and analyzing the angular acceleration of rotating objects. Mastering these concepts will help you tackle a wide range of problems.
Match the terms with their definitions:
| Term | Definition |
|---|---|
| 1. Torque | A. The perpendicular distance from the axis of rotation to the line of action of the force. |
| 2. Lever Arm | B. The point around which an object rotates. |
| 3. Axis of Rotation | C. The force that causes an object to rotate. |
| 4. Rotational Equilibrium | D. The state where the net torque on an object is zero. |
| 5. Moment of Inertia | E. A measure of an object's resistance to changes in its rotational motion. |
