Mechanical Energy Quotes

There is nothing like a doorbell to precipitate the potential into the kinetic.

The height of the pulleys from the ground was twelve yards, and consequently, when the weights had descended through that distance, they had to be wound up again in order to renew the motion of the paddle.

When I'm building my dome in my chapel, and I had a vision - I've worked on perpetual motion and I haven't never give it up yet. I still think it could be done, perpetual motion. I had a vision of a un resist able windmill.

Energy may be likened to the bending of a crossbow; decision, to the releasing of a trigger.

Although mechanical energy is indestructible, there is a universal tendency to its dissipation, which produces throughout the system a gradual augmentation and diffusion of heat, cessation of motion and exhaustion of the potential energy of the material Universe

The fall of a given weight from a height of around 365 meters corresponds to the heating of an equal weight of water from 0° to 1°.

The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have proved by actual experiment that, in exact proportion to the force with which this machine works, heat is abstracted from the electrical battery. You see, therefore, that living force may be converted into heat, and that heat may be converted into living force, or its equivalent attraction through space.

The waterwheel accepts water and turns and gives it away, weeping.

In speaking of the Energy of the field, however, I wish to be understood literally. All energy is the same as mechanical energy, whether it exists in the form of motion or in that of elasticity, or in any other form. The energy in electromagnetic phenomena is mechanical energy.

It is sunlight in modified form which turns all the windmills and water wheels and the machinery which they drive. It is the energy derived from coal and petroleum (fossil sunlight) which propels our steam and gas engines, our locomotives and automobiles. ... Food is simply sunlight in cold storage.

You all know how powerful and varied are the effects of which steam engines are capable; with them has really begun the great development of industry which has characterised our century before all others.

A ball will always come to rest halfway down a hill, unless there is sand or water at the bottom.

A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work.

Energy is a concept that has been coined by physicists. There is no observable thing known as energy anywhere.

In order to lift a certain object from the ground, we have to use energy. But then to sustain it at that level, we have to keep on adding energy, or otherwise, the object falls to the ground. It's exactly the same thing with the sound.

I imagine horses in the engine, their manes flying, their breaths steaming, their nostrils flaring as they gallop.

The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and can neither be increased nor diminished.

The half minute which we daily devote to the winding-up of our watches is an exertion of labour almost insensible; yet, by the aid of a few wheels, its effect is spread over the whole twenty-four hours.

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer.
