Kinetic energy is a manifestation of the product of mass times velocity. Mass has no upper limit, velocity has (so far as we know). The maximum velocity of anything with mass is c, the speed of light.
How you would accelerate a massive object to this speed is not known. The more massive an object the more difficult it is to accelerate it.
If you could then the most massive object travelling at this velocity would have the most kinetic energy.
When the planet is closest to the star which it is orbiting.
This is because when it is closest its potential energy is lowest, as there is no net energy loss in a stable orbit this PE must be converted to KE when the planet moves closer to the star and back again as it moves further away. I think this is also explained by Kepler's laws
The kinetic energy is at a maximum when the speed is a maximum. Kepler's 2nd law says that the radius vector - the line from the Sun to the planet - sweeps out equal areas in equal times, which means that the speed is a maximum when the distance is at a minimum. That point is called perihelion.
Each planet reaches perihelion once in each revolution round the Sun.
The Earth is at perihelion in January when its distance is 1/60 less than the average distance (1/60 is the eccentricity of the Earth's orbit). That means that the Earth's speed is 1/60 higher than the average and the kinetic energy is 1/30 or 3.3% more than the average.
What situation where you thinking about? Check the formula for kinetic energy; as you can see, it's proportional to the mass, and it is also proportional to the square of the speed. Therefore, for one and the same object, kinetic energy is highest when the object moves fastest.
At the point in its orbit closest to the central body, since
that's the point where its orbital speed is greatest.
An object at its highest point has the greatest potential energy. Only moving objects have kinetic energy at the moment they are in motion.
Where the velocity is the maximum, e.g. mcV and |V|=c, the speed of light.
zero
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
potential energy is the energy that an object has stored up. kinetic energy is an object in motion. :) hi ppl :)))))))
The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.
When an object - rocket or otherwise - rises, its kinetic energy gets converted to gravitational potential energy. At its highest point, if it rises directly upwards, all the kinetic energy will be converted to gravitational potential energy. However, its movement may also have a sideways component; in that case, not all the kinetic energy is converted to potential energy.
It's potential energy decreases.
Yes, a falling object has only potential energy at its highest point at rest. The same object will also have all kinetic energy and no potential energy the instant just before striking the ground at its highest velocity at ground level.
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
Some of its potential energy changes to kinetic energy.
The name for the combination of the kinetic and potential energy of an object is heat.
potential energy is the energy that an object has stored up. kinetic energy is an object in motion. :) hi ppl :)))))))
The total kinetic and potential energy of the molecules of an object is thermal energy.
An object's potential energy doesn't depend on its speed. You can do anything you like with the object's speed, and it has no effect on potential energy.
The difference between potential and kinetic energy all comes down to a very simple property of the object. If an object is moving, then it has kinetic energy, or kinetic energy is the energy of movement. Potential energy is energy that is stored in an object and can be released under the right conditions.
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic energy.
Mechanical energy is kinetic or potential energy associated with the motion and position of an object.
Kinetic energy is the energy that an object has because of its motion. The energy depends on the speed and mass of the object.
the energy in an object about to fall is potential energy then kinetic energy because when the object is not falling, it has potential energy but when it's actually falling, it has kinetic energy.
