Question

Think back to levers lab.when you changed the position of the fulcrum what else did you change?

Answer 1

The Effort Force.

I took the test and got it right.

Answer 2

The amount of Effort

Step-by-step explanation:

The mechanical advantage of a lever is changed when the distance between the pivot point (fulcrum) and the weight is changed. If the distance between the fulcrum and the effort is increased, the effort needed to lift a weight decreases proportionally.
