When the field is applied, the electrons cannot make such transitions acquire kinetic energy from the electric field due to the exclusion principle. As a result, the material does not conduct electricity. The highest energy band is partially filled in a conductor but completely filled in an insulator. Visit this simulation to learn about the origin of energy bands in crystals of atoms and how the structure of bands determines how a material conducts electricity.

Explore how band structure creates a lattice of many wells. A semiconductor has a similar energy structure to an insulator except it has a relatively small energy gap between the lowest completely filled band and the next available unfilled band. This type of material forms the basis of modern electronics. The only difference is in the size of the energy gap or band gap E g between the highest energy band that is filled the valence band and the next-higher empty band the conduction band. In a semiconductor, this gap is small enough that a substantial number of electrons from the valence band are thermally excited into the conduction band at room temperature.

These electrons are then in a nearly empty band and can respond to an applied field. As a general rule of thumb, the band gap of a semiconductor is about 1 eV. A band gap of greater than approximately 1 eV is considered an insulator.

Potential Energy

For comparison, the energy gap of diamond an insulator is several electron-volts. Samuel J. Measured in kilograms in our formula above, the mass is a critical factor in determining the potential energy of a body. With you and I, mass would be referring to the content of the individual or the company embarking on a task. By content I refer to the planning, the preparedness, the funding, the logistics, the contingency systems, the tools, the resources.

I refer to the availability of expertise, knowledge and understanding of a task ahead. To perform any task we must be prepared. We must have mass.

To create mass we must have passion. Unfortunately, managers, business owners, families and even the consumers fail to appreciate this. They fail to understand that to be good is not the limit, to be the best is just the beginning! How fast are you? How quickly do you think you can deliver?

It happens all the time! Senior management gives me a report to do and I start slow…really slow. My acceleration is always usually pretty slow at the beginning, then just before the deadline, I start to pick it up.

I start working in frenzy at dangerous break-neck speeds. In order words, friction challenges motion.

Kinetic Energy and Potential Energy

Naturally, this would make friction an enemy of the physical world and indeed mechanics worldwide would tell you how it causes wear and tear and destroys even the strongest of alloys. They are right. Challenges, like friction, cause wear and tear. On the flip side, friction does have its benefits. We would slide our way to work because there would be nothing to stop your feet once they hit the ground.

Our pens would simply slide along the page being unable to pause to make words and sentences. Our cars would move without stopping. The break system, primarily designed around friction would cease to exist. So challenges, just like friction, help us get it right.

The Physics of Capitalism

They help us place our feet at the right spots so we can walk when we have to and run when we need to. These relationships are expressed by the following equation:. In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength 9. To determine the gravitational potential energy of an object, a zero height position must first be arbitrarily assigned.

Typically, the ground is considered to be a position of zero height. But this is merely an arbitrarily assigned position that most people agree upon. Since many of our labs are done on tabletops, it is often customary to assign the tabletop to be the zero height position. Again this is merely arbitrary. If the tabletop is the zero position, then the potential energy of an object is based upon its height relative to the tabletop.

For example, a pendulum bob swinging to and from above the tabletop has a potential energy that can be measured based on its height above the tabletop. By measuring the mass of the bob and the height of the bob above the tabletop, the potential energy of the bob can be determined. Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy.

A tripling of the height will result in a tripling of the gravitational potential energy. Use this principle to determine the blanks in the following diagram.

Knowing that the potential energy at the top of the tall platform is 50 J, what is the potential energy at the other positions shown on the stair steps and the incline? The second form of potential energy that we will discuss is elastic potential energy. Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Elastic potential energy can be stored in rubber bands, bungee chords, trampolines, springs, an arrow drawn into a bow, etc. The amount of elastic potential energy stored in such a device is related to the amount of stretch of the device - the more stretch, the more stored energy.

Newton's First Law of Productivity

Springs are a special instance of a device that can store elastic potential energy due to either compression or stretching. A force is required to compress a spring; the more compression there is, the more force that is required to compress it further.
