Answer:
Gravity is the force that allows for all objects to fall.
Answer:
Hooke's law, given by 
is denoted with a negative sign to regard that the direction of restoring force that occurs opposite in direction of the force that caused the displacement 
. F represents the force required to create a spring displacement of .
Explanation:
As with many things in physics, the negative sign represents direction. In this case, after a spring is displaced a distance of from equilibrium, the restoring force created by the spring will be in opposite direction of the force applied to move the spring there, represented by F.
Answer:
Decrease
Explanation:
If you were on the Moon, which has significantly less mass than the Earth, your weight would: decrease
The point that seemed to be giving me a complicated time was being able to distinguish the difference and meaning of weight and mass and being able to apply that to a problem. I kept mixing up the definitions. For example in homework 3.1, one question asked:
If you were on the moon, which has significantly less mass than the earth, your mass would:
a. increase
b. decrease
c. stay the same
d. become zero
The definition of mass is the amount of matter in an object. The definition of weight is the amount or unit of force. For me, I just had to remember that when it asked about weight, it wasn’t referring how heavy an object is. After I was able to recognize that when it came to weight, questions became easier.
The final and correct answer was decreasing. The answer is because the Moon’s mass is less. This means the gravitational force is less on your body, therefore, your mass is going to be lighter
