In the case of mechanical energy, the work (the energy transferred) is equal to force times distance. If a post (for example) just supports a weight, there is a force involved, but no energy - since the distance is zero (it doesn't move). There are other types of energy; the definitions are different, but mechanical energy can be converted into these other types of energy, too.
Kilos is weight therefore you cannot convert weight factors in to length
That is impossible to anwer. An area cannot be converted to a weight, mass or force.
FALSE. Mass is a measure of the amount of matter within an object. Weight is the force of gravity on a mass. To get weight from mass, multiply mass by the gravitational constant of whatever planet you are on. MASS IS NOT WEIGHT!!!
millimetres is length, kilograms is weight. they cannot be converted
When a human being loses weight the lost weight is converted to heat energy and radiated.
When an object falls down, potential energy is converted to kinetic energy.
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
It is converted to fat stores.
If you have an object on the roof it has potential energy of weight x height above the ground. When you drop it off the roof it is converted to kinetic enemy as it hits the ground, of value 1/2 its mass x velocity squared.
None. Weight lifting do not burn any carbohydrates. Carbohydrates are converted into glucose in the body which later is used as energy.
Portion control directly helps you to lose weight by tipping the scales in favor of the output of caloric energy. When you carefully monitor your portion sizes, you decrease the amount of food that you eat.
That refers to potential energy related to a gravitational field. In simple terms, an object that is higher up has more energy than one that is lower. This energy can be converted into other energy types; for example, when an object falls down, its potential energy is converted to kinetic energy (i.e., movement). The formula for gravitational potential energy is: GPE = wh (weight x height) or equivalently: GPE = mgh (mass x gravity x height)
By weight or volume.
The source of energy is the hanging weight(s) in the tower....or a wound spring if a more modern mechanism is used. Think of a Grandfather Clock. It is "wound" by pulling on a chain which raises the hanging weight(s) in the body of the clock. The force of gravity pulling on the weights provides the energy to run the clock. Note however, that you actually input the energy initially, when you pulled on the chain to raise the weight. That rise increased the weight's Potential Energy, which is then slowly converted back to Kinetic Energy as the weight slowly is lowered by the Clockwork mechanism.
The energy change that takes place as a cup falls off a table is the cup's potential energy decreases while the cup's kinetic energy increases.
Yes. This is part of Einstein's theory: E = mc 2 "Energy equals mass times the speed of light squared." The amount of energy contained in 1 gram of matter is equal to the number you get when you square the speed of light. This concept lead to the idea that an atomic bomb is possible.
