If a machine moves a load of 800n through the distance 20cm. Calculate the work done by the machine taken that the load is the service force.
work = force * distance
To calculate the work done by the machine, we can use the formula:
Work = Force x Distance
In this case, the force exerted by the machine is 800N, and the distance is 20cm. However, it is important to note that the force and distance should be in the same units.
Since the distance is given in centimeters, and the SI unit for distance is meters, we need to convert the distance from centimeters to meters by dividing by 100.
20cm ÷ 100 = 0.2m
Now we have the force (800N) and the distance (0.2m) in the same units.
Substituting these values into the formula:
Work = 800N x 0.2m
Work = 160 Joules
Therefore, the machine does 160 Joules of work to move the load of 800N through a distance of 20cm.
