Suppose you wanted to lift a heavy rock with a lever. Would you place the fulcrum near rock or near the part of the lecer where you are pushing? Explain.

The way levers work is by multiplying the effort exerted by the user. Specifically, to lift and balance an object, the effort force the user applies multiplied by its distance to the fulcrum must equal the load force multiplied by its distance to the fulcrum. Consequently, the greater the distance between the effort force and the fulcrum, the heavier a load can be lifted with the same effort force.
