Newton-metre is the unit of work.
Unit of work:
Work is defined as the amount of energy transferred by a force acting through a displacement. It is measured in joules (J) or newton-metres (Nm). Work can be calculated by multiplying the force applied to an object by the distance it moves in the direction of the force.
Newton-metre:
The newton-metre (Nm) is a derived unit of energy, work, or torque in the International System of Units. It is equal to the amount of work done when a force of one newton acts through a distance of one metre in the direction of the force. Therefore, one newton-metre is equivalent to one joule.
Power:
Power is the rate at which work is done or energy is transferred. It is measured in watts (W) or joules per second (J/s). The unit for power is not newton-metre.
Momentum:
Momentum is the product of an object's mass and its velocity. It is a vector quantity and is measured in kilogram metres per second (kg·m/s). The unit for momentum is not newton-metre.
Gravitational intensity:
Gravitational intensity is the force exerted by gravity on an object. It is measured in newtons per kilogram (N/kg). The unit for gravitational intensity is not newton-metre.
In conclusion, the correct answer is option B - Newton-metre is the unit of work.
