the rider uses energy to do work going up the mountain this energy changes into kinetic energy on the way down
Coasting, free-riding,
The potential energy present in a vehicle at the pot of a mountain gets turned into kinetic energy as the vehicle travels down the mountain. Eventually that kinetic energy is dispersed as friction turns it into heat.
the conservation of energy is important becasue we could cause the earth to be dry and rainy that could ruin the planters and buildings
Describe mountain top peak
On the mountain, before they fall, they have "potential" energy. When they are falling they have "kinetic" energy.
Conserve energy today! Exist until years passed away! Save energy..and be happy!
You could select a basic scenario to show, using Sankey diagrams that no energy has been lost. For example you could use the simple example of a bulb tuning electrical energy into useful light energy and wasted heat energy.
The Law of Conservation of Energy is not the work of a single scientist. The knowledge about this law developed gradually over several centuries, as more and more types of energy were recognized to be equivalent. For example, at some moment somebody recognized that kinetic energy could be converted into potential energy and vice versa, and at another moment, somebody else recognized that mechanical energy could be converted to heat energy at a fixed ratio.
i think there is no objection .if it goes any where wrong i could achive success in my project
Perpetual motion would only fit the principle of the conservation of energy if it was a machine that moved that did not have any friction or produce any sound or produce any form of heat or energy that could be lost in any way. Since no such machine is possible to create, as far as we know, perpetual motion is declared an impossibility and does NOT fit the principle of the conservation of energy. Energy will undoubtedly be lost somewhere in a moving system.
valley
Organisms that consume other organisms for energy.
lethargic; weak
