Real world situation to explain the relationship between work and power

- - You and your partner both get the same job to do:

Each of you gets a pallet of bricks, and you have to

put the bricks up on the bed of a truck, by hand.

Both pallets have the same number of bricks.

The pallet is way too heavy to lift, so you both cut the bands

that hold the bricks, and you lift the bricks from the pallet onto

the truck, by hand, two or three or four bricks at a time.

- - You get your pallet of bricks onto the truck in 45 minutes.

- - Your partner gets his pallet of bricks onto the truck in 3 days.

- - Work = (force) times (distance).

You and your partner both lifted the same amount of weight

up to the same height. You both did the same amount of work.

- - Power = (work done) divided by (time it takes to do the work).

Your partner took roughly 96 times as long as you took

to do the same amount of work.

You did it faster. He did it slower.

You produced more power. He produced less power.
