Question
.Which of the following statements about torque is correct? *1 pointA. Torque is a scalar quantityB. Torque is measured in joules (J)C. Torque can only be produced by a single forceD . Torque causes rotational motion around an axis
Solution
The correct statement about torque is: "D. Torque causes rotational motion around an axis".
Here's why:
A. Torque is not a scalar quantity. It is a vector quantity because it has both magnitude and direction.
B. Torque is not measured in joules. The SI unit for torque is the Newton meter (N.m).
C. Torque can be produced by multiple forces, not just a single force.
D. Torque does indeed cause rotational motion around an axis. This is the principle behind any rotating object, from a simple wheel to complex machinery.
