Is Solar energy potential or kinetic at its starting point?
Its kinetic energy since its the energy of the moving photons coming out of the sun.
Is nuclear energy a kinetic or potential energy?
We recognize about 9 unique sources of energy. Kinetic and potential energy are commonly called mechanical energy. And atomic/nuclear energy is another form of energy. Here are the 9 types below :magnetickinetic (movement energy)heat (thermal energy)lightgravitational potentialchemicalsoundelectricalelastic potentialnuclear.So if you say, what kind of energy nuclear is, I'll say, it's an energy which has three components, in molecular level: rotational, vibrational and translational. However, all of the three are commonly called internal energy. In this universe, all atoms or molecules have them. So, nothing to specify uniquely for nuclear energy.
Is solar energy potential or kinetic energy?
Solar Energy is Kinetic.
If an objects mechanical energy is equal to its potential energy how much kinetic energy does the objects have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0. The kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest. The speed, and thus the kinetic energy of a single object is frame-dependent (relative): it can take any non-negative value, by choosing a suitable inertial frame of reference. For example, a bullet passing an observer has kinetic energy in the reference frame of this observer. The same bullet is stationary from the point of view of an observer moving with the same velocity as the bullet, and so has zero kinetic energy.
Where is the maximum kinetic energy in planets?
The Kinetic Energy (KE) of a planet is K = 1/2mV^2m is the mass of the planet. V is the tangential velocity of the planet’s orbit.So, the practical maximum kinetic energy depends the highest velocity point in its orbit.Since a planet’s KE increases with an increase it its velocity, the KE of a planet is highest when it's at the highest velocity of its orbit.Planetary orbits are normally ellipses. The velocity of the planet is at its peak when the planet is at the closest point to the sun, which is called the perihelion.On the opposite side, a planet's KE will be at its lowest point when the planet is at its aphelion, which is where it is the furthest away from the sun.If the orbit was perfectly round, and the sun perfectly in the center of the orbit, then the KE would be the same during the entire orbit.
Does the sun contain kinetic or potential energy? Why?
Yes. The sun is a big, heavy ball of ultra-compressed (more like crushed under gravity) hydrogen and helium that moves, so it has plenty of kinetic energy. Towards the very centre of the sun, where the crush is the fullest, individual atoms are transformed into a soup of free particles that bounce around to create very peculiar nuclear interactions. Gigantic stars have even crazier phenomena going on inside, but there is still plenty we don’t know about our own Sun.nuclear reaction chain starting from the subatomic fusion of hydrogen [from The Solar Furnace ]The radiation from nuclear fusion generates has a lot of kinetic energy upon exit from the chromosphere (Not to mention the pretty light and necessary heat that adorns our sky). Whenever it hits an object, it exchanges some of that with a little potential energy.It also has a lot of potential energy in form of its large gravity well. Imagine water flowing to the drain in a sink.By the law of conservation of energy, kinetic and potential energies always coexist in a system. In physics, we only take the extreme cases of pure potential and pure kinetic energies because they make interesting descriptions. It can help to answer questions like: If we take this value of X… can we do Y in situation Z? If something does not fall in the ballpark of the expected range limit, then it’s probably wrong… Unless we’re dealing with lone (or few) particles, but that is not the case here.
How do we prove that change in kinetic energy equals to work done?
We know that W=Fs where W is work done and F is force and s is displacement. Here there is a condition that initial velocity is 0. SoW=mas (F=ma)W=m*[math](V^2-u^2)/2[/math]W=m[math]v^2/2[/math]This work done is stored as Kinetic Energy. So now we know thatKE=m[math]v^2/2[/math]Now again we assume a condition where u is not 0. Following above steps we reached.W=m*[math](V^2-u^2)/2[/math]W=[math]mv^2/2 - mu^2/2[/math]W=Final kinetic energy - Initial kinetic energy.
What kind of energy is possessed by a falling stone?
in falling stone, potential energy gets continuously to kinetic energy, till when, it falls on the ground,when both of them become zero. so, falling stone possess both potential energy and kinetic energy, provided that potential energy gets reduced continuously, till it finishes on ground.
