Why would there be more gravitational potential energy than kinetic energy?
There would be more gravitational potential energy than kinetic energy when an object is at a high elevation or position above the ground, where the gravitational potential energy is proportional to the height of the object. As the object falls, the potential energy is converted to kinetic energy, so at any point during the fall, the sum of potential and kinetic energy remains constant.
What 2 broad categories of pumps are commonly used as the energy source in a liquid system?
Positive displacement pumps and centrifugal pumps are the two broad categories commonly used as the energy source in a liquid system. Positive displacement pumps provide a constant flow rate, whereas centrifugal pumps generate flow through the conversion of rotational kinetic energy to hydrodynamic energy.
What energy transformation occurs when someone pushes the bottom on a doorbell?
Mechanical energy from the person pushing the button is converted into electrical energy, which activates the doorbell mechanism. The electrical energy then produces sound energy as the bell rings.
How is energy transferred from potential to kinetic on a roller coaster?
Energy is transferred from potential to kinetic on a roller coaster as the coaster descends from a higher elevation to a lower elevation. As the coaster moves downwards, gravitational potential energy is converted into kinetic energy. This energy transfer allows the coaster to gain speed and momentum.
Why kinetic energy is always positive?
Kinetic energy is always positive because it is a measure of the energy of an object in motion. Regardless of the direction of motion, the velocity term in the kinetic energy equation is squared, which ensures that the kinetic energy value is positive.
When light activates the electrons of chlorophyll then those electrons have a less or more energy?
When the light "activates" the electrons, it kicks them up into higher orbitals where they have more energy. That extra energy is utilized to power the photosynthesis reaction.
What is the nature of graph between kinetic energy and mass when velocity is constant?
When velocity is constant, kinetic energy is directly proportional to mass. This means that as mass increases, kinetic energy also increases proportionally. The graph would be a straight line with a positive slope.
If the energy of an electron is found with Energy equals hc divided by lamda which contains only positive terms how can the energy of a bound electron be negative?
The h in the hc stands for plancks constant which is 6.63 x10^-34, which is negative. :)
What are pumped storage reservoirs?
The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
What activates chloryphyll?
The chlorophyll on exposure to light energy becomes activated by absorbing photons(photon is the smallest unit of light energy)
What is Boltzman's constant?
The Boltzman's constant is the physical constant relating to temperature to energy.
What causes positive energy balance and what are the effects of positive energy balance?
Positive energy balance is when energy intake exceeds expenditure weight is gained
Why do you have to conserve energy when infact the energy of this world is constant?
While the TOTAL amount of energy remains constant, on the other hand, useful energy can, and will, be converted into unusable energy.
Where does the sled have the most energy?
The sled has the most energy at the highest point in its descent, where it possesses maximum potential energy due to its elevation. As it slides down, this potential energy is converted into kinetic energy, increasing the sled's speed. However, at the bottom of the slope, the sled has maximum kinetic energy, while its potential energy is at its minimum. Thus, the sled's total mechanical energy remains constant, assuming no energy losses.
Does a potato have energy?
depends if your talking about positive and negative energy the answer would be: yes it does it has positive energy in it
