This document provides formulas for calculating force, pressure, moment of force, work done, current, voltage, and resistance. It states that force can be calculated as pressure multiplied by area and is measured in newtons. Pressure is calculated as force divided by area, with units of newtons per square meter or pascals. Moment of force is calculated as force multiplied by the perpendicular distance from the force to the pivot and is measured in newton-meters. Work done is calculated as force multiplied by the distance moved by the force in the direction of the force, with units of joules. Current can be measured in amperes using an ammeter connected in series. Voltage can be measured in volts using a voltmeter

- SI Unit: N/m2 or pascal (Pa)
TO CALCULATE MOMENT OF FORCE:
- Force(n) x perpendicular distance fro force to pivot
- Measured in Nm(newton-metre)
TO CALCULATE WORK DONE:
- Force x distance moved by the force in the direction
of the force
- Measured in joule
TO CALCULATE CURRENT:
- Measured in ampere(A)
- Can be measured using an ammeter
- By connecting an ammeter in series
TO CALCULATE VOLTAGE:
- Measured in volt (V)
- Can be measured by a voltmeter
