    Graduate Nature of Laws of Physics (Gravity)

    Gravitational and electric forces obey the inverse square law because of the way the energy spreads. Its purely geometric thing. The energy equipotentials are spheres and they have inverse square dependence with the radius.

    Advantages/disadvantages of twisted wires VS wires bundled next to each other

    Yes, I guess it has to do something with that, although there must be some other torsional strengthening added. I couldn't find this tread about Forth road bridge.

    Undergrad How dampening works versus conservation of momentum

    Yes, you are right. I was thinking of the energy but I thought that i can interchange those terms which it's not the case.

    Advantages/disadvantages of twisted wires VS wires bundled next to each other

    Rope needs to resist tension and torsion. The tensile strength will be the same on both types of rope. But the rope with twisted wires can resist torsional forces too.

    Undergrad How dampening works versus conservation of momentum

    The linear momentum of the car through the piston by friction is transversed to the linear momentum of the fluid (oil) molecules inside the dumpers, their speed increases (temperature goes up). If there is temperature difference between the dumpers and the surrounding air, heat is transversed...

    High School What happen to the kinetic and potential energy during the boiling and melting?

    Yes, that energy is called latent heat (heat of transformation). I'm glad I was able to help.

    High School What happen to the kinetic and potential energy during the boiling and melting?

    Substances are composed of atoms or molecules. They are in constant motion (vibrating or translating depending on the state of the substance). Temperature is the average kinetic energy of a molecule of that substance. There are connections between the molecules (chemical connections) -...

    Undergrad Help with understanding gravity and why some things float?

    Gravity creates pressure difference in fluids.

    High School Temperature Definition & Calculation - What is T?

    Yes, temperature is the average kinetic energy of the particles forming some object. Temperature relates with the internal energy of that object. Heat is energy transfer between bodes with different temperatures. Heat can be transferred by conduction, convection and radiation. So in vacuum is...

    High School Liquid Pressure: How Does It Exert Pressure?

    Relative motion is motion of two or more bodies in respect of one and other, two cars on a highway are going in same direction one with 100 km\h and the other with 110 km\h, so there is relative motion between the two cars, with speed of 10 km\h. If the fluid is liquid then there are...

    High School Liquid Pressure: How Does It Exert Pressure?

    There will be pressure due too the molecules motion, but not pressure difference in the liquid, the molecules will be bouncing from the body, equally from all sides, so there wot be a force present, no relative motion.

    Undergrad Thermal radiation from the sun

    Yes, I meant that. Thank you.
  13. V

    High School Liquid Pressure: How Does It Exert Pressure?

    Yes, that is because the molecules of the liquid move in all directions.

    Undergrad Thermal radiation from the sun

    Yes, the photons don't lose their energy through distance, their density is decreasing and it goes down inversely proportional to the distance traveled.

    Undergrad Centripetal force ( Swinging a bucket in a vertical motion )

    No object wants to move in a circle. It goes in a straight line or is stationary unless some force is acting on it. So in order to move in a circle you must push constantly in direction of the center of the circle to keep it in that motion otherwise the object will continue in a straight line...
