28.6 Relativistic Energy

- The National Spherical Torus Experiment has a fusion reactor that can produce helium.
- A small amount of fuel is converted into a large amount of energy.

- A fusion reactor can change mass to energy.
- Accomplishing this requires an understanding of energy.
- Nuclear Reactors are proof of the existence of relativistic energy.

- One of the most important laws in physics is the conserve of energy.
- Each form of energy can be converted to any other form.
- The total amount of energy in a system remains constant.

- If the definition of energy is changed to include the possibility of mass changing to energy, then energy is still conserved.
- The case for relativistic energy is the same as the case for relativistic momentum.
- Several fundamental quantities are related in ways not known in classical physics.
- All of these relationships have consequences.
- Some of the most fundamental and spectacular new insights into nature can be found in the altered definition of energy.

- The laws of physics are the same in all frames according to the first postulate of relativity.
- If we define energy to include a relativistic factor, Einstein showed that the law is valid.

- There are many aspects of the total energy that we will discuss, among them are how kinetic and potential energies are included in.
- At rest, total energy is not zero.

- The rest mass increases if energy is stored in the object.
- Mass can be destroyed to release energy.
- The implications of the first two equations were so broad that they were not completely recognized for some years after Einstein published them.
- Einstein understood and described the meaning and implications of his theory.

- The rest energy of a mass is calculated.

- A gram is half the mass of a penny.
- The speed of light can be used to find the equivalent rest energy.

- The knowns should be identified.

- The appropriate equation can be chosen.

- The knowns should be plugged into the equation.

- This is a lot of energy for a small mass.
- We don't notice the energy because it isn't available.
- Rest energy is large because the speed of light is a very large number, so that is huge for any mass.
- The rest mass energy for 1.00 g is about ten times the energy released by the atomic bomb and ten times the energy released by a large aircraft carrier.
- Huge amounts of energy can be obtained from the destruction of mass if a way can be found to convert rest mass energy into other forms.

- Nuclear weapons and nuclear power plants are examples of how mass can be converted into another form of energy.
- Einstein described some of the examples when he first proposed the correct form of energy.
- Nuclear radiation had been discovered in the previous decade, and it had been a mystery as to where it came from.
- In certain nuclear processes, a small amount of mass is destroyed and energy is released and carried by nuclear radiation.
- The amount of mass destroyed is so small that it's hard to find any missing.
- Although Einstein proposed this as the source of energy in the radioactive salts then being studied, it was many years before there was broad recognition that mass can be converted to energy.

- Mass is now considered a form of energy because of the relationship between rest energy and mass.

- Prior to Einstein's work, there was no hint of this.
- The source of the Sun's energy, the energy of nuclear decay, and even the source of energy keeping Earth's interior hot have all been attributed to such conversion.

- The rest mass of the object increases because the energy input becomes part of the total energy of the object.

- Mass is created in a system by all the stored and potential energy.
- One of the great laws of the 19th-century was the concept of total mass being constant.
- This example helps answer the questions.

- A car battery can move 600 ampere-hours of charge at 12.0 V if it is fully charged.

- The energy stored in the battery is what the battery can provide in the form of electrical potential energy.
- The charge is the product of the current and the time.
- We can use this to calculate the battery's increase in mass.
- A simple ratio is converted to a percentage.

- The knowns should be identified.

- The appropriate equation can be chosen.

- To solve for the unknown, Rearrange the equation.

- The knowns should be plugged into the equation.

- convert hours to seconds by writing amperes A as coulombs per second.

- The knowns should be identified.

- The appropriate equation can be chosen.

- The knowns should be plugged into the equation.

- Since energy is divided by a large number, the increase in mass and percent are very small.
- To notice the increase, we need to be able to measure the mass of the battery to a precision of a billionth of a percent.
- The mass variation is hard to observe.
- The change in mass is so small that we may not be able to verify it.
- In nuclear processes in which the percentage of mass destroyed is large enough to be measured, the answer is found.
- When the energy has been used, the mass of the fuel is smaller.
- In that case, the stored energy has been converted to heat and electricity and the rest mass has decreased.
- This is also the case when you use the energy stored in a battery, except that the stored energy is much greater in nuclear processes, making the change in mass measurable in practice as well as in theory.

- We have rest energy.
- The work increases the amount of energy.

- The expression for total energy and rest energy is different from the classical one.

- A binomial expansion is an expression of an infinite series of terms.
- Most terms are very small in some cases.
- The expression is not exact, but it is a very accurate approximation.

- The same amount of classical and relativistic energy can be found in the same place.

- When an object approaches the speed of light, it is more interesting to investigate what happens to the energy in the object.
- We know that as the speed of light increases, so that KErel also increases as the speed of light increases.
- An infinite amount of work and an infinite amount of energy input are needed to accelerate a mass to the speed of light.

- The speed of light can be reached by an object with mass.

- The speed of light is the ultimate speed limit for any particle.
- The fact that velocities less than always add to less is consistent with this.
- The ultimate speed limit has been confirmed in numerous experiments.
- No matter how much energy is put into a mass, it cannot reach the speed of light.

- The graph shows how the energy approaches the speed of light.
- It is not possible for an object to reach the speed of light.
- The classical energy is similar to the relativistic energy at low speeds.
- More energy is needed to reach high velocities than was predicted.

- An electron has a speed.

- Since the velocity is close to, the expression for relativistic kinetic energy must be used.
- The first thing we will do is calculate the relativistic factor.
- If less than a few percent of the classical energy is used, we can see that it is not the same.

- The knowns should be identified.

- The appropriate equation can be chosen.

- The knowns should be plugged into the equation.

- Extra digits will be carried because this is an intermediate calculation.
