What is an example of chemical to mechanical energy?
-- A bowling ball rolls off of a shelf. It spends some fraction of a second converting its gravitational potential energy into kinetic energy, whereupon it dramatically expends all of its mechanical energy upon impact with the floor. -- Water pours over a waterfall. Its gravitational potential energy is converted to kinetic energy on its way down to the valley below the falls. If you stick a waterwheel or turbine into the cascade in the right way, you can rob some of the water's mechanical energy to generate electricity or grind wheat.
Is the total mechanical energy of bumper cars conserved?
If you keep your foot on the floor you are adding energy all the time, but if two cars meet without drive engaged, the total energy before and after must balance. Of course kinetic energy can be absorbed by the car's bodywork so the resultant kinetic energy will be altered by collisions. Some energy will also be absorbed by the floor and appear as heat due to friction.
How are Mechanical and thermal energy related?
Thermal Energy is a form of kinetic energy, or the energy of moving objects. Thermal energy is energy an object has when it is not being disturbed by an outside force. For example, if you leave a book on the floor, it had thermal energy. But if you push the book, the thermal energy is converted to kinetic energy, or the energy of movement. Though the type of energy is being changed, the total amount of energy in the object is kept the same.
When an elevator descends from the top of a building and stops at the ground floor what becomes the energy that had been potential energy?
Most of elevator's potential energy was transferred to its massive counterweight, which was lifted high up in the shaft as the elevator descended. Some of its energy was dissipated in both heat and noise. Also, don't forget about the kinetic energy that the car had while it was moving. Most of that was absorbed by either a mechanical brake, or else by the motor that's usually replacing the energy lost from the system.
How can doing work on an object increase it's kinetic energy?
I lift a book from the floor and place it on my desk.The amount of work I do on the book is the amount by whichits gravitational potential energy has increased . . .M G Hwhere 'M' = mass of the book, 'G' = acceleration of gravity, 'H' = height of the table above the floor.By the way, when I increased the energy of the book, I also increased its mass. The change in mass isdM = dE / c2
Is the energy produced by a ball rolling on the floor called mechanical energy?
Chemial
What energy is causing your feet to feel vibrations in the floor in a place where music is extremely loud?
Most people would tell you it would be mechanical but no its sound energy.
What energy transformations occur in a floor polisher?
Electrical energy-mechanical energy-sound enegy-heat(heat is the by-product or new product)

What happens to the potential engrgy of a bookas it dops from a desk to a desk to the floor?
Converted from potential energy to kinetic energy during the fall, then a small amount of energy is converted into sound and pretty much everything else is converted to heat. If the floor was soft (carpet for example) there would be a small amount of energy converted back to potential energy as the fibres were compressed and then this would be converted into kinetic energy and the cycle would repeat until equilibrium was attained.
A car is lifted a certain distance in a service station and therefore has a potential energy relative to the floor If it were lifted twice as high how much potential energy would it have?
The same amount of potential energy again.
Does a roller coaster have more potential energy at the top of the hill or at the bottom?
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
What energy transformation occurs in a pencil sharpener?
mechanical energy
What is the verb for collision?
The verb for collision is collide.Other verbs are collides, colliding and collided.Some example sentences are:"We collide into a heap on the floor"."Still not used to ice skating, she collides with her best friend"."We stopped the car colliding into the fence"."They collided into us".
How is mechanical energy related to potential energy and to kinetic energy?
The relationship is that mechanical energy is the sum of kinetic energy plus potential energy. Think of a brick sitting on the edge of a table. The brick has potential energy proportional to the mass of the brick and the height of the table: E = m g h where m = mass, g = gravitational acceleration, h = height If the brick falls off the edge, it will begin to accelerate at g, the rate of gravitational acceleration (9.8 m/s2). If v is the velocity of the brick, it has kinetic energy proportional to the quare of the velocity: E = (m v2)/2 Just before the brick finally hits the floor, all of its potential engergy has been converted to kinetic energy. During the moment of impact, that kinetic energy is converted to noise and vibration.
What amount of energy dreseases?
Total energy is always conserved. However, it is possible to convert one type of energy to another. With some limitations, you can usually convert many types of energy to many other types. Whenever this happens, the amount of one type of energy decreases, while the amount of another energy increases. For example: if an object falls down, its potential energy decreases; its kinetic energy increases. Once it crashes to the floor, its kinetic energy is converted into heat - in other words, kinetic energy decreases, while heat energy increases.
