2005年8月6日 · If you use this equation for velocity, your calculations will show energy is conserved. (substitute the velocity equation into the specific kinetic energy equation) You have to calculate the specific potential energy for both perihelion and apohelion, as well. In other words, substitute the radius of perihelion for R and the radius of apohelion ...

2021年10月11日 · (Microscopic kinetic energy becomes macroscopic potential energy) 4: A gas spring powered toy moves, until stopped by friction. (Microscopic kinetic energy becomes microscopic kinetic energy and microscopic potential energy) 5: A gas spring powered toy accelerates, then moves without friction.

2009年11月18日 · Kinetic Energy: K=(1/2)mv^2 Potential Gravitational Energy: U=GMm/r Rotational Angular Momentum: Lrot=Iw Moment of Inertia of a Sphere: (2/5)MR^2 Moment of Inertia: mr^2 Angular Velocity: 2pi/T Translational Angular Momentum: Ltrans=mvr Centripetal Force: Fc=mv^2/r The Attempt at a Solution Part A

2003年12月23日 · Potential energy is the energy that an object possesses due to its position or state. Kinetic energy is the energy an object has due to its motion. How are potential energy and kinetic energy related? Potential energy can be converted into kinetic energy, and vice versa. For example, when an object is dropped from a height, its potential energy ...

2021年11月11日 · (1/2)mv^2 = mgh is not correct, the correct is mgh = (1/2)kx^2 (elastic potential energy= gravitational potential energy), which gives h=0.05 (important notice: we assume that x=0 at the equilibrium position). When the ball re bounces and reaches maximum height it will have zero speed and kinetic energy, and E=mgh.

2013年8月8日 · I haven't watched the video, but the minus comes from Hamilton's Principle which kinda says "Of all the possible paths in a time frame the path that is taken is the one that minimizes the time integral of the DIFFERENCE between potential and kinetic energy".

2012年11月12日 · FAQ: Potential & Kinetic Energy of Revolving Object (e.g. Moon) What is potential energy in a revolving object? Potential energy is the energy that an object has due to its position or state. In the case of a revolving object, it is the energy that is stored in the object's position in relation to its center of rotation.

2023年5月14日 · That potential energy changes sign with buoyancy. When a flying bomb explodes, the combustion products form a huge sphere of gas followed by a central depression, which stops almost instantly. That is because the cross-section of the low-density sphere produced, is up against hundreds of tonnes of atmosphere.

2011年12月11日 · Homework Statement I don't want to tell the problem I just want to know how to solve it. There is a mass and a velocity and the ramp is inclined let's say 30 degrees. The object is going up the ramp with a force of friction opposing it. Find the distance the object travels before...

2011年2月4日 · The whole energy of all the molecules (kinetic and potential) is the internal energy of the substance. If you place another substance(2) in contact with the substance(1) the molecules of the two substances will come in contact and will tend to even their kinetic energies (temperatures). Heat is the energy that has been transfered.
