What does torque measure?

• A. The force that opposes motion
• B. The force causing linear motion
• C. The force producing rotation
• D. The net force on an object

Answer: (C)

Torque measures the effectiveness of a force in causing an object to rotate around an axis. It is defined as the product of the force applied and the distance from the point of rotation, often referred to as the lever arm. This rotational effect means that torque is crucial for understanding how forces influence the motion of rotating bodies, such as wheels, gears, and levers. When a force is applied at a distance from an axis of rotation, it attempts to turn the object. The greater the force or the longer the distance from the pivot point, the greater the torque produced, which in turn results in a more significant rotational effect. This concept is essential in various applications, from simple tools like wrenches to complex machinery and vehicles. Understanding torque helps in analyzing situations where rotation is involved, which is not adequately captured by simply looking at net forces or linear motions.
