Which statement is not true of simple machines?
A.They can change the amount of work done on an object.
B.They can change the distance over which you apply a force.
C.They can change the direction in which you apply a force.
D.They can change the amount of force you exert.
i think it is b
They change the amount of force needed!!!
Or in this case exert but its D

whats the fu33 anwser
Deez nuts
To determine which statement is not true of simple machines, let's analyze each statement:
A. "They can change the amount of work done on an object."
This statement is true. Simple machines can indeed change the amount of work done on an object by either increasing or decreasing the force required.
B. "They can change the distance over which you apply a force."
This statement is also true. Simple machines can amplify or reduce the distance over which a force is applied, allowing an easier or more efficient way to accomplish a task.
C. "They can change the direction in which you apply a force."
This statement is true. Some simple machines, such as pulleys, levers, or gears, can change the direction of the force applied.
D. "They can change the amount of force you exert."
This statement is also true. Simple machines can increase or decrease the amount of force required to accomplish a task, making it easier or more manageable.
Based on this analysis, the statement that is not true of simple machines is B, "They can change the distance over which you apply a force." This statement is indeed true, so it is the correct answer.
the answer is C. They can change the direction in which you apply a force.
time to rethink
a simple machine allows you to apply less force over a greater distance
... the amount of work done is the same
