UNIT 2
Force and Work
LESSON 8
Force and Work Unit Test
Someone who took the test can you please dump the answers below? Thanks I am in dire need to pass this horrid hellscape of a class, it may be easy but my mind is in too much stress to even focus to comprehend it.
What is the relationship among force, mass, and acceleration?(1 point)
Responses
Force equals mass divided by acceleration.
Force equals mass times acceleration.
Force equals mass plus acceleration.
Force equals mass minus acceleration.
Anne exerts a force of 34.1 N to pitch a softball. She moves the ball 1.8 meters before releasing it. What amount of work did Anne do on the ball?(1 point)
Responses
61.38 J
32.3 J
18.9 J
35.9 J

screw you people who arent helping
1. 1,600 joules
2. decrease; direction of the force
3. class 1 = L, F, E (or E, F, L)
class 2 = F, L, E (or E, L, F)
class 3 = F, E, L (or L, E, F)
4. They reduce the amount of force needed to move an object to do the same amount of work.
5. 392 Joules
6. to reduce the force needed to lift the box and change the direction of the force
7. It is the point where the bar touches the smaller rock.
8. a car that traveled 80 kilometers on 5.0 liters of gas
9. machine C
10. It changes the direction of the lifting force to work with gravity.
11. Use a stiffer lever to reduce energy lost bending the lever.
12. 60%
