The measure of the force that can cause an object to rotate about an axis is called:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. torque.
The measure of the force that can cause an object to rotate about an axis is called torque. Torque, also known as the moment of force, is calculated as the product of the force applied and the distance from the axis of rotation to the point where the force is applied. It is a vector quantity, with both magnitude and direction, and is crucial in understanding rotational motion and mechanics. The formula for torque is τ = F × r × sin(θ), where F is the force, r is the distance, and θ is the angle between the force and the lever arm.
