force is N = kg-m/s^2
work is J or N-m
To determine which units work is measured in, let's break down the options:
a) n: "n" typically represents a count or dimensionless quantity, so this does not seem to be a suitable unit for measuring work.
b) n-m: "n-m" is the unit for torque, which is a measure of the turning force. Torque is not the same as work.
c) m: "m" typically represents meters, which is a unit of length. While length is related to work, it alone does not fully measure work.
d) kg m/sec²: This unit represents force. Although force is related to work, it alone does not fully measure work.
To find the correct answer, we need to consider the unit that combines force and displacement. The unit for measuring work is derived from multiplying force and displacement. The correct unit for measuring work is:
Work = Force × Displacement
The SI unit for force is Newtons (N) and the unit for displacement is meters (m). Therefore, the correct unit for measuring work is:
d) kg m/sec² × m = kg m²/sec²
So, work is measured in the unit kg m²/sec² (kilogram-meter squared per second squared).
