Energy has a mass equivalent. This is so small as to be negligible in most everyday processes on Earth, but for truly large amounts of energy, it can be significant -- the total energy generated by the sun, for example, works out to over four million tons of mass per second.

You already know the mass-energy equivalence formula, even if you don't know that's what it's called: it's the famous E = mc2.

A good-sized nuclear power plant might put out 1000 megawatts of power. The total power output of such a plant for 25 hours amounts to 90,000,000,000,000 joules, which is the equivalent of about a gram of mass.

How speed and weight affect an amount of kinetic energy?

Kinetic energy is directly proportional to an object's speed squared, meaning that as an object's speed increases, its kinetic energy increases exponentially. Weight itself does not directly affect an object's kinetic energy, but it can impact the object's speed due to factors like friction and resistance. Ultimately, both speed and weight play a role in determining the kinetic energy of an object in motion.


How does the weight of a ball affect how high it bounces?

The weight of a ball can affect how high it bounces due to the conservation of energy principle. A heavier ball will generally bounce lower than a lighter ball because more of the energy will be absorbed by the deformation of the ball when it hits the ground. Lighter balls tend to bounce higher since less energy is lost to deformation.


How do weight and kinetic energy relate?

Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.


Does energy have weight?

No, energy does not have weight. Weight is a measure of the force of gravity acting on an object, while energy is a measure of the ability to do work or cause change.


Is lifting weight kinetic or potential energy?

Lifting a weight involves potential energy, as it represents stored energy due to the position of the weight in relation to the Earth's gravitational field. Once the weight is in motion, it converts to kinetic energy.

Does weight affect the ammount of kinetic energy in an moving object?

Not weight - mass. On Earth the two are proportional, but it is better not to confuse the two.

If energy has mass and mass has weight do we weigh more when we have lots of energy?

The idea is not that energy 'has' mass. The idea is that mass and energy can be directly related to one another in an equation. Also, mass does not always have weight; you can weigh a mass only when the mass is in a gravitational field. Having lots of 'energy' has no affect on your weight. The above stated answer is partly wrong because Einsteins E=MC2 equation qualitatively states that energy in reality does have mass. It is only that the speed of light is so great in term's of numerical value that any change in energy would not effectively affect your total mass. However weight is simply a force so you can not say that if my mass increases on earth i would have the same weight as on the moon for the same weight.


Can the weight on a rocket affect the speed?

Yes. A heavier rocket will need more energy to achieve a certain speed.

How can weight impact energy?

It depends on the type of energy, of course.Gravitational potential energy is equal to weight multiplied by height - so you can see that it is directly proportional to weight.Some other types of energy, such as kinetic energy, heat energy, etc., depend on the mass of an object - not on its weight. But since weight is also directly proportional to the mass, you might say that if the weight increases, certain types of energy will also increase - even though the energy is not exactly the result of the weight in this case (both the weight and the energy depend on the mass).

Lifting a weight involves potential energy, as it represents stored energy due to the position of the weight in relation to the Earth's gravitational field. Once the weight is in motion, it converts to kinetic energy.


Does reflexology affect height?

Reflexology does not affect height but could affect weight. Reflexology can release toxins that have built up in the body which might affect weight gain or loss.
