Correct Answer: Torque
Solution : The correct answer is Torque.
A torque is a twisting or turning force that tends to cause rotation around an axis. Torque is the cross product between the distance vector and the force vector.
The force that may twist an item about its axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction. It is a vector quantity.
