Question 9 of 16

9. Question
What is a force multiplier?
- A lever in which the resultant force is larger than the effort force
- A lever in which the resultant force is smaller than the effort force
- A lever in which the resultant force is equal to the effort force
- All of these answers
Correct

Incorrect
Question 10 of 16

10. Question
How does a force multiplier work?
- The load is closer to the pivot than the effort
- The load is further to the pivot than the effort
- The load is low
- The effort is high
Correct

Incorrect
Question 11 of 16

11. Question
Why would we use a force multiplier?
- To lift up a heavy item with less effort force
- To lift up a light item with less effort force
- To lift up a heavy item with more effort force
- To put in more effort force than necessary
Correct

Incorrect
Question 12 of 16

12. Question
What is a distance multiplier?
- A lever in which the load moves further than the effort
- A lever in which the load does not move as much as the effort
- A lever in which there is no load
- A lever in which there is no effort
Correct

Incorrect
Question 13 of 16

13. Question
How do distance multipliers work?
- The effort is closer to the pivot than the load
- The effort is further to the pivot than the load
- The effort is as close to the pivot than the load
- The pivot and the load are both equally far from the pivot
Correct

Incorrect
Question 14 of 16

14. Question
Why would we use a distance multiplier?
- To move something a long distance quickly
- To move something a short distance
- To move a light object a short distance
- To move nothing
Correct

Incorrect
