Thepotential energyis energy the system possesses by virtue of its configuration.───势能是体系由于它的相对位置而具有的能. If only conservation forces act, the kinetic energy plus thepotential energyremains constant.───如果只受保守力的作用, 则动能加势能是一个恒量. ...
The Law of Conservation of Energy states that energy cannot be created or destroyed. In other words, the total energy of a system remains constant. This is an
In summary, the particle released from rest at point A inside a smooth hemispherical bowl of radius 30.0 cm has a gravitational potential energy of 0.633J relative to point B, a kinetic energy of 0.62J at point B, a speed of 2.4m/s at point B, and a potential energy of 0.422J and ...
If you start a small box on an incline plane from rest, at the bottom of the incline all the gravitational potential energy will have converted to kinetic energy, ideally. At each point of the path sliding down the box will have the sum of the gravitational potential energy plus the ...
That gravitational potential energy is equal to the work done ON an object to oppose gravity rather than the work done ON an object by gravity amounts to nothing more than a sign convention. We adopt the sign convention that we do so that "Kinetic Energy" plus "Gravitational Potential ...
When the Western Europe high appeared and shifted eastward, energy conversions increased and energy propagated from North America to Eurasian as a form of interaction energy flow. The baroclinic conversion between transient-eddy kinetic energy (K e) and transient-eddy available potential energy (A e...
In classical mechanics, the passage of a particle through a potential barrier is possible only when the particle’s total energy ℰ—kinetic energy plus potential energy—exceeds the height of the barrier, that is, when ℰ≥ V0. If, however, the energy of the particle is insufficient to...
The true available potential energy (APE) of an isolated feature (e.g. a warm-core ring) in a basin is the difference in the potential plus internal energy between the observed and reference state. The reference state is that in which the same fluid is redistributed adiabatically to a stabl...

(b) What is the ratio of its kinetic energy to the potential energy of the ball-Earth system when the ball is at an altitude of 10.00 m? I know that the change in mechanical energy is kinetic energy plus potential energy, but I don't know how to get either of those. 4) A ...
