Question 1 Report
Which of the following has the same unit as the moment of a force?
Answer Details
The moment of a force has the same unit as work, which is joule (J).
The moment of a force is the product of the force and the perpendicular distance from the line of action of the force to the pivot point. It is also known as torque. The unit of force is newton (N), and the unit of distance is meter (m). Therefore, the unit of moment of a force is Nm.
Work is defined as the product of the force and the distance moved in the direction of the force. The unit of work is also joule (J). Therefore, the moment of a force and work have the same unit, which is joule (J).
The other options do not have the same unit as the moment of a force. Force is measured in newtons (N), power is measured in watts (W), momentum is measured in kilogram meters per second (kg m/s), and impulse is measured in newton seconds (N s).
