Question 6 • Physical Science

While researching machines and how they work, Tika finds several online sites that discuss how force and distance are related to work done by a machine. How should Tika most likely describe this relationship between force and distance to her study group?

Answer
A
If the input force is less than the output force, then the input distance must be the same as the output distance.
B
If the input force is equal to the output force, then the input distance must be greater than the output distance.
C
If the input force is greater than the output force, then the input distance must be greater than the output distance.
D
If the input force is less than the output force, then the input distance must be greater than the output distance.
