Question 1 • GA-GSE Physical Science B

Which is a result of using a machine?

Answer
A
The mechanical advantage makes the work output greater than the work input.
B
The machine can put out force without having any force applied to it.
C
A large force can be exerted through a long distance to have a small force exerted through a short distance.
D
A large force can be exerted through a short distance to have a small force exerted through a long distance.

Explanation

A machine can trade force for distance: a large input force applied over a short distance can produce a smaller output force over a longer distance. In an ideal machine, the work input equals the work output, so increasing the output distance means the output force is smaller. The correct choice is “A large force can be exerted through a short distance to have a small force exerted through a long distance.”
