gravity

What questions do laws answer?

It answers the "what" questions, what happens under specific conditions or produce the same result no matter the conditions

what questions do theories answer?

The answer to a hypothesis that hasn't been proven wrong yet (it can change)

What does the law of gravity say?

all objects with mass atract each other. The more mass on the object the stronger the gravitational pull. (things fall)

What was Newton's theory of gravity?

Gravity is a force of attraction that pulls masses together.

What was Einstines theory of gravity?

Gravity is a force of attrction that pushes masses together.

What is MEST?

matter, energy, space, and time

How does trampoline theory explain warp theory?

the trampoline theory is when heavy bowling ball is in middle. you drop a marble and it goes to the center, you push it and it spins in circle. The focus point of the balls depends where the heaviest mass is (think person, bowling ball, and marble)

Why are orbits evidence for warp theory?

bigger push = orbit

Right angle velocity is what maintains the orbit

What does the inverse square law say?

Change in distnace has bigger efect then change in mass

What is LUG?

Newtons Law of Universal Gravity

LUG broken down

Gravity that happens between two masses

Practice problems with inverse squared Law:

2 objects are 25m aprt and move to be 5m apart. How does Fg change?

D↓5x → Fg↑25x

Who is Von Jolly?

known for his contributions to experimental physics, specifically his work on gravity (experements with scales)
