Since potential energy is negative in the case of a positive and a negative charge pair, the increase in 1/r makes the potential energy more negative, which is the same as a reduction in potential energy The result from Example 71 may be extended to systems with any arbitrary number of charges In this case, it is most convenient to write theThe amount of potential energy that an object possesses depends on the object's mass or weight, its height above the surface, and the strength of the gravitational field If the other factors are the same, a heavy object will have more gravitational potential energy than a lighter object An object 1 mile (16 km) up in the sky will have moreSome of the potential energy is "lost" in other energy conversion processes For example, the friction of the wheels and other moving parts converts some of the energy to heat mass of marble, distances between points, curve radii) and calculations (Eg, Ek, v) One sample calculation (equation, substitution, answer) for each unique
Potential energy is the energy associated with position, like a ball held up in the air When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion There are five types of kinetic energy radiant, thermal, sound, electrical and mechanical Let's explore several kineticFew Examples of Potential Energy Potential energy is stored in a stretched rubber band eg in a catapult, where it provides the energy needed to propel The muscle of an archer who is set to fire an arrow from the bow has stored potential energy Potential energyElectric potential energy is the energy that is needed to move a charge against an electric field You need more energy to move a charge further in the electric field, but also more energy to move it through a stronger electric field Imagine that you have a huge negatively charged plate, with a little positively charged particle stuck to it
