... Many such examples as we just saw lead us to propose a natural law. Remember that a natural law is a statement of how nature seems to work - it is not “derived” from anything more basic, it is observed to fit the results of observations (experiments). Energy can neither be created nor destroyed (tha ...

6.P.3A.1 Properties and Sources of Energy
... A stretched rubber band has potential energy. This is called elastic potential energy. A book on a shelf has potential energy. Since gravity can pull the book to the floor, this is called gravitational potential energy. The height and mass of an object affect gravitational potential energy. Gravit ...

TYPES OF ENERGY
... How is energy stored? • All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups -- renewable (an energy source that we can use over and over again) and nonrenewable/conventional (an energy source that we are using up a ...

Law of Conservation of Energy Amusement Park Physics
... Work is the transfer of energy through motion. In order for work to take place, a force must be exerted through a distance. The amount of work done depends on two things: the amount of force exerted and the distance over which the force is applied. There are two factors to keep in mind when decidin ...

... Therefore, you must figure out a way to measure those two variables, and then calculate the ratio. You must determine whether you are going to measure the static or the kinetic coefficient of friction. Static friction opposes the movement of objects so this must be measured as the maximum force (on ...
