Hi, I would like to ask you what happens when you change (gradually) a mass of one body in a classical two-body-problem. May it lead to such results? Many thanks. Flor

Hi all! Imagine you have an ideal sphere (made of steel or plastics). Then fill it completely with some fluid, e.g. water. Then rotate it very fast. What happens to a fluid inside? I suppose that it will try to change its shape (from spherical to flat). But there is no space for any size...

But maybe, who is then accelerating... :)

Suppose two velocities v1 and v2, eg. v1 = 5 km.s-1 and v2 = 10t km.s-1 (acceleration times time, time integration).

Hi, may I ask you about a help (or where to find proper study materials)? [SIZE="5"]I have two particles - A and B. A is moving at constant velocity in a gravitational field with constant acceleration (due to gravity). B is moving on spiral trajectory at accelerated velocity in a...

Hi, May I ask you, i have a question about gases. Take a gas and give it under high pressure conditions. Then immediately give the same gas under no pressure conditions (some free space). Then my question is what will happen to the temperature of this gas? Can we observe the increase in...

Is it because the intensity of gravitational field (g) of Earth is much bigger than the intensity of gravitational field of an apple? I can give you another question - what happens if the Earth radius will expand for example 1 x 10^30 times? Then the Earth will fall on apple! Is it true? :)

I know, but is it observable? Or what is the best way to explain what we observe? I see an apple falling down :)

Why does the Earth attract the apple and the apple at the same time does not attract the Earth (the Earth does not move to the apple)?

Good morning, I would like to ask you... Is it possible to make a liquid matter from a solid matter with a help of ultrasound? At first, what happens if the ultrasound travels through a solid matter (for example quartz)? What happens to a solid matter during a positive amplitude (compression)...
