Energy cannot be doubled or maximized. The relevent concept is conservation. Energy is always conserved, never increasing, never decreasing. Energy can by used in a way that converts more of it into the work you want to do and "wastes" less energy on other work like creating unwanted heat, noise, or vibration, or in the case of burning fuels, efficiencies can be gained by capturing more of the heat in the industrial processes associated with the conversion of fuel into heat, electricity, or mechanical energy.
When the wavelength of light is doubled, the energy of photons decreases by half.
When the amplitude of a wave is doubled, the energy in the wave increases by a factor of four. This is because the energy in a wave is directly proportional to the square of the amplitude. So, if the amplitude is doubled, the energy will increase by a factor of four.
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
Kinetic energy is directly proportional to the square of the momentum. Therefore, if the momentum is doubled, the kinetic energy will increase by a factor of four.
If the velocity of a body is doubled, its kinetic energy will increase by a factor of four. This relationship is because kinetic energy is proportional to the square of the velocity. Additionally, the momentum of the body will also double.
When the height of a body is doubled, its potential energy also doubles. This is because potential energy is directly proportional to the height of an object in a gravitational field.
If mass is doubled while velocity remains constant, the kinetic energy will also double since kinetic energy is directly proportional to the mass. This is because kinetic energy is calculated using the formula KE = 0.5 * mass * velocity^2.
When the potential difference across a capacitor is doubled, the energy stored in the capacitor increases by a factor of four.
When a car's speed is doubled, its kinetic energy increases by a factor of four. This is because kinetic energy is proportional to the square of the velocity.
How can the product of a reaction be maximized?
The speed halves.
If the mass is doubled, the kinetic energy will also double, assuming the velocity remains constant. Kinetic energy is directly proportional to the mass of an object, so increasing the mass will result in a proportional increase in kinetic energy.
