Can someone explain to me how to calculate the gravitational constant?

Hi, so this is the problem I'm having trouble with. I googled it, and it says that the gravitational constant is always constant, but how do I calculate it? Can someone explain to me exactly how? It would also be really nice if someone could explain to me how the gravitational force works, i.e., how…

How could a person learn to fly without aids?

I mean literal flying like in Dragon Ball, where the characters can neutralize the gravitational structure on Earth and everywhere else through advanced Ki control. How could a similar or different concept be applied to real life? I've also thought about implementing a kind of jet propulsion system under the sole of the shoe that,…

break solar mass?

Determine the mass of the sun using only the following three pieces of information.3 G = 6.67*10^-11 Earth's orbital period around the sun T = 365.26 days Distance Earth – Sun d = 1.496βˆ™10^11 m = 1 AU (one astronomical unit) Thanks!

Task?

Hey guys, I have this task and its solution in front of me. I understand how everything was triggered except for c. Why did they use this formula? Do they really have to consider the 200 km, or would it be acceptable as it is? An explanation would be helpful.

[Physics] Calculate gravitational acceleration on the Earth's surface?

Good evening, Is my calculation wrong here? I used values ​​from the previous problem to arrive at the solution (for the Earth's mass M and the Earth's radius r). Task 6 was probably not intended this way. I appreciate your help. Task: Solution to task 6 My calculations for task 6:
