1.How has e=mc2 affected you?
It affects everything that occurs in our world; each time you flex a muscle, breath in or out, think a thought or beat your heart, you’re converting mass into energy, and each time you digest a meal, you’re converting energy back into mass. Everything that adds or subtracts energy from a system causes its mass to change
2. How would you compare the four “forces”?
Well, base on what we have learned STRONG NUCLEAR FORCE, ELECTROMAGNETIC FORCE, and WEAK NUCLEAR FORCE are not directly interacting with each other but rather generate a field which affects the behavior of distant objects. From quantum field theory, these fields are associated with one or more particles and are believed to be the result of some fundamental symmetries of nature. Also, I believe that Electromagnetism and gravity are inverse square forces that propagate at the speed of light, I am not sure that base on what we have learned we can compare Gravity with other forces since it does not count as a force anymore.
3. What is the function of gravity?
I was not sure about the answer but I found this:
height = initial height + initial upward velocity * time - 0.5* gravity * time^2 where moving direction is the counter-gravity direction.
