What is torque, in physical terms?
AThe turning effectiveness of a force
BThe linear effectiveness of a force
CThe total energy stored in a spinning object
DThe mass distribution of a rotating body
Answer & Solution
Correct answer: A. The turning effectiveness of a force
1. Torque is described as the angular version of force.
2. It measures how effectively a force twists something around a pivot, not how hard it pushes in a line.
3. tau = rF sin(theta), where r is measured from the pivot to where the force acts.
