6. What is power?
- Rate at which work is done
- Force exerted over a distance
7. What happens when to pressure when you have a smaller area?
- No pressure
- More pressure
- Less pressure
8. What is the center of mass?
- The point at which all plumb lines meet
- The center of an object
9. How can you increase power?
- Doing something faster(taking less time to do) and using more strength to push something
- Moving something up and down
10. What is force measured in?
11. How can you get a resultant force?
- By multiplying the forces
- By finding the difference between forces
- By adding up the forces
12. What is tension?
- Stretching force
- Squeezing/squashing force
13. What is the relationship between Hooke's Law?
- Force and the stretch of a spring
- Force and weight of a string
- Weight and stretch of a string
14. When does the object stay stationary or have a constant speed?
- When all the forces add up to an odd number
- When all the forces cancel out
- When all the forces add up to an even number
15. What is a moment force?
- The turning effect
- The moment something happens
- The time at which the force changes
16. What happens to pressure when you have a larger area?
- No pressure
- Less pressure
- More pressure
17. When is there a greater turning effect?
- Further from the pivot point and greater force applied
- Closer to the pivot point and less force applied
18. When is there less of a turning effect?
- Closer to the pivot point and less force applied
- Further from the pivot point and greater force applied
19. What does a manometer measure?
- Measures the atmospheric pressure (height of the mercury inside the glass)
- The difference between atmospheric pressure and gas pressure
- The difference between atmospheric pressure and liquid
