With a gravitational force like that on Jupiter, roughly 2.53 times stronger than on Earth, could one even move and survive? And under what physical conditions would that be easiest? Because with less mass, one often also has less muscle mass/strength. And besides, there's the heart and circulatory system, bones and joints and organs, and…
I've often wondered where gravity gets its energy from, since energy is needed to move matter. And I believe that gravity is essentially a perpetual motion machine.
It's about problem 11. My answer doesn't match the one in the solution. I've already looked through everything, but I can't find my mistake. Could someone help me? That would be really nice!
I really don't like learning by heart and want to understand the connections. I understand the gravitational force and the centripetal force, but which force represents the hypotenuse of the force triangle???
Hello, I'm writing a physics exam tomorrow, and although I know a little bit about astrophysics, I'm a bit lost because of my calculator. I'm looking for the gravitational force between Earth and the Sun. I know it should be 3.54∙10²², but my calculator shows 5.305∙10³³
According to Einstein, gravity is a consequence of the curvature of space?! Why then do we still need (hypothetical) gravity?
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…
We have topic: -Torque -statistical moment -offset moment -Clearing/cutting free components -Equilibrium conditions of mechanics -level/spatial force system -Torque calculations using the formula M=rx F -Kinematics and dynamics (statics, kinetics) -Support reactions (cables, bars, 1, 2, 3-valued supports,…) What might such a school assignment look like, and how many tasks would typically be included? Could…
Hello, I have a physics question. A colleague and I are standing on a ladder right now because we were talking about gravity. Weight is defined by how strongly it is attracted to the Earth. So, when I step on the scale, I'm like a child. But isn't the gravitational force basically the same? (For…
I mean, the downward gravitational force isn't always the same as the tensile force pulling the body upward, is it? And I know a rope only absorbs tensile forces, but then the force has to be drawn on the cable drum and not on the rope, because the downward force is the gravitational force, and…
According to Isaac Newton, the falling speed of a body depends only on air resistance, since mass and inertia balance each other out (F=mxa). According to him, a balloon filled with iron should fall at the same speed as one filled with air.
Hey can someone tell me the calculation method to find out mNeptune task 3
