YO MY MOMS GONNA OOF ME INTO THE MOON IF I FAIL THIS-

Moonen is trying to do a homework problem. She needs to give the amount of force it takes to move a rock. She knows force is 50, but she isn't sure what unit to use to represent force. What unit should she use?

Question 1 options:

50 N


50 m/s2


50 m/s


50 m

Question 2 (1 point)
Moonen hopped on one leg for 10 m. It took her 25 s to finish. She knows her speed is 250, but 250 what? What units should she use for her speed?

Question 2 options:

250 s


250 m/s


250 m


250 N

Question 3 (1 point)
Moonen is chopping wood. She is using an wedge to split the wood. How does a wedge make chopping wood easier?

Question 3 options:

It decreases the amount of force needed to split the wood, but it must be applied over a longer distance


It changes the direction of the force from a straight line to one that rotates the wood


Force is applied to the think end and that force in transferred to the sloping sides to split the wood


It moves the wood from one elevation to another easier

Question 4 (1 point)
Moonen has put a spiral staircase into her house. (No idea why when she lives in a single floor house). A spiral staircase is an example of a screw. How does a screw work for a staircase?

Question 4 options:

It allows you to pull down (adding your body weight to the pull force down) rather than picking something up.


It changes the direction of the force from a straight line to one that rotates around a central point. It makes the stairs take up less room.


It decreases the amount of force needed, but it must be applied over a longer distance. It makes climbing stairs easier.


It makes it easier to move heavy stuff from one elevation to another due to the slant.

Question 5 (1 point)

Question 5 options:

screw


wedge


lever


inclined plane

Answer 1

Explanation:

Answer 1: 50 N

Answer 2: 250 m/s

Answer 3: Force is applied to the thin end and that force is transferred to the sloping sides to split the wood.

Answer 4: It changes the direction of the force from a straight line to one that rotates around a central point. It makes the stairs take up less room.

Answer 5: Inclined plane.
