A particle moves along the x axis.In order to calculate the torque on the particle, you need to know:
A)the velocity of the particle
B)the rotational inertia of the particle
C)the point about which the torque is to be calculated
D)the kinetic energy of the particle
E)the mass of the particle

Question

Quizplus · Accepted Answer

Torque is defined as the cross product of the lever arm (distance from the pivot point to the point of force application) and the force applied. Therefore, knowing the point about which the torque is to be calculated is essential to determine the lever arm distance, which is crucial for calculating torque. The other options, such as velocity, rotational inertia, kinetic energy, and mass, do not directly influence the calculation of torque without considering the force applied and the lever arm distance from a specific point.
