> > kinetic energy of a single object is frame-dependent (relative): it can take any non-negative value, by choosing a suitable inertial frame of reference. For example, a bullet passing an observer has kinetic energy in the reference frame of this observer, but the same bullet is stationary, and so has zero kinetic energy, from the point of view of an observer moving with the same velocity as the bullet > When accounting only for [|mass], [|gravity] , and [|altitude] , the equation is: > where //U// is the potential energy of the object relative to its being on the Earth's surface, //m// is the mass of the object, //g// is the acceleration due to gravity, and //h//is the altitude of the object.[|[4]] If //m// is expressed in [|kilograms], //g// in [|meters per second squared] and //h// in [|meters] then //U// will be calculated in [|joules]. > Hence, the potential difference is > > while the energy stored in an [|inductor] (of [|inductance]//L//) when current //I// is passing via it is > .This second expression forms the basis for [|superconducting magnetic energy storage]. > > One cannot touch a force field; hence, it is not an object—but obviously, it exists. All one has to do to prove its existence is to place a natural magnet, such as an iron nail, within the magnetic field. Assuming the force field is strong enough, the nail will move through space toward it—and thus the force field will have performed work on the nail.
 * The more speed one has or more things to move = more energy or stronger amount of energy could be use just to power one and or many things
 * __Potential energy exists when a [|force] acts upon an object that tends to restore it to a lower energy configuration. This force is often called a [|restoring force] . For example, when a [|spring] is stretched to the left, it exerts a force to the right so as to return to its original, unstretched position. Similarly, when a mass is lifted up, the force of [|gravity] will act so as to bring it back down. The action of stretching the spring or lifting the mass requires energy to perform. The energy that went into lifting up the mass is stored in its position in the [|gravitational field], while similarly, the energy it took to stretch the spring is stored in the metal. According to the law of ﻿﻿ [|conservation of energy] ﻿﻿, energy cannot be created or destroyed; hence this energy cannot disappear. Instead, it is stored as potential energy. __
 * The strength of a gravitational field varies with location. However, when the change of distance is small in relation to the distances from the center of the source of the gravitational field, this variation in field strength is negligible and we can assume that the force of gravity on a particular object is constant. Near the surface of the Earth, for example, we assume that the acceleration due to gravity is a constant //g// = 9.81 m/s 2 (" [|standard gravity] "). In this case, a simple expression for gravitational potential energy can be derived using the //W// = //Fd// equation for [|work], and the equation

 * You must have enough kinetic energy to supply the amout energy need to do one thing!!!
 * We will have dominos to have kinetic energy
 * **Potential energy is converted into kinetic energy**. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy. A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy also happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States.
 * **Magnetic energy** and [|electric energy] are related by [|Maxwell's equations]. The potential energy of a [|magnet] of [|magnetic moment]**m** in a [|magnetic field]**B** is defined as the [|work] of magnetic force (actually of magnetic [|torque]) on re-alignment of the vector of the magnetic dipole moment, and is equal:
 * When we drop the poper it was potential and elastic energy then when it popoed it converted to kinectic
 * enrgy in the flashlight lab changed by kinectic when we moved the medal to turn on the light and friction when the batteriese touch to make electrical energy.
 * The general answer is that energy conversion is the conversion of one type of energy into another. We use this principle all the time every day. For instance, we use chemical energy in a battery to create electrical energy to power an electric starter motor. This motor uses the electrical energy to create mechanical energy to start a vehicle. The vehicle converts chemical energy into mechanical energy to make the vehicle go. If you think about the types of energy, you can come up with all sorts of things that change one type of energy to another type. A microphone converts the mechanical energy of sound into electrical energy. There is a boatload of other examples.
 * In fact, it might actually be more precise to say that energy is the ability of "a thing" or "something" to do work. Not only tangible objects (whether they be organic, mechanical, or electromagnetic) but also non-objects may possess energy. At the subatomic level, a particle with no mass may have energy. The same can be said of a magnetic force field.

When we used the flashlight lab we had kinectic energy from the pin moving to turn on the flash light and eltroeclamic from the batteries also thermal from the light.
 * and if we use magnets to move something that would be eltormagnetic energy
