Work is done when a force causes an object to move in the direction of the force. Work can be calculated using the formula Work = Force x Distance. Work is measured in joules, named after scientist James Joule. Power is a measure of how quickly work is done and is calculated by dividing work by time. Power is measured in watts, named after James Watt who helped advance steam engines.

1. Work and Power:
Work is done when a force causes the object to
move in the same direction as the force is going.
Example: if you lift a box from the floor to the
table top, you exerted a force on the box upward, the
box moved upwards so work was done.
Example #2: if you pick up the box, work was
done when you applied the force upwards. If you
stand and hold the box you can still feel the upward
force being applied, but because the box isn’t moving
no work is being done.
You can have force in multiple directions but only
the force that is causing the movement is the force
that is doing work.
To figure out work you would use the
following formula:
Work (measured in joules) = force (in Newtons) X
distance (in meters)
Or
W(J) = Fd

2. Work is measured in joules named after James P.
Joule a scientist who proved the law of conservation
of energy
Power is measured in Watts, named after James Watt
the person who perfected the Steam Engine and laid
the path for the industrial revolution.
Power is how quickly work is done.
To determine power you divide work by time
Or
P= W
