Question 1 • GA-GSE Physical Science B

What does a machine change to make work easier? Select three options.the amount of work donethe amount of force appliedthe time needed to do the workthe direction of a forcethe distance over which a force is applied

Answer
A
the amount of work done
B
the amount of force applied
C
the time needed to do the work
D
the direction of a force
E
the distance over which a force is applied

Explanation

A machine can make a task easier by changing how much force you apply, changing the force’s direction, or changing the distance over which the force acts. For example, a ramp reduces the force needed by spreading the work over a longer distance. A machine does not reduce the total work in an ideal system, and changing the time is not one of these basic ways it makes work easier.
