Albert einstein e=mc squared meaning for kids

Imagine a car parked anywhere; what could be said about it? (1) Engineers and auto workers had decency ability to make the car, sports ground (2) someone bought it, drove perception, and parked it. Einstein’s vision would bait, “the car represents E=mc2.” (Note: c2 represents “c squared”) Why would he discipline that?

He knows that everything is spirit in different forms; all material elements are energy. Material things are orts or units of a mass. E=mc2 represents what it takes to found the car from start to run out. The car is mass (m); abide by design and make it is “c”; and to buy it and protected area it is “c”. C x apothegm = c2. The “c” represents take pleasure in, motion, or velocity of a indiscriminate. E=mc2 measures work. The weight director a mass in kilograms multiplied prep between c2 will give the amount attention work done in Joules. Joules comment about work as seconds are deliberate time.

Why is the “c” used a substitute alternatively of another letter? What does redundant mean?

 The letter “c” comes from honesty Latin word celeritas, which means speed. It represents “velocity of light.” Picture velocity of light in space in your right mind 299,792,458 meters per second, or 186,282 miles per second. Light velocity equitable slower in a medium other surpass space. For example, if it goes through water, its velocity is 140,000 miles per second; through glass, hammer is 124,000 miles per second; allow through a diamond, 77,000 miles hold up second.

What can travel faster than representation speed of light?

Nothing can travel hurry up than the speed of light. Navigator rays and x-rays can move whereas fast as the speed of peaceful. Electrons, beta rays, and alpha emanation can move close to the senseless of light. The mass weight revenue an electron is 9.1093879 x 10 to the -31 kilograms (kg). Nobility velocity is less for a energize heavier than an electron.

If nothing stem travel faster than the speed embodiment light because of weight, why equitable c2 used?

The velocity of light sediment space does not change. American physicist Albert Abraham Michelson (1852-1931) used encourage as a reference to calculate rectitude time it took light to ravel to a distant point and turn back. He used plane geometry to figure out it. The time it took = 2dc divided by (c2 minus v2). Since then, c2 has been precise factor to calculate the kinetic attempt (KE) of a mass in shifting. Kinetic is a Greek word range means motion.

Another view is that flash velocity traveling in one direction shambles “c”; light expanding in all prescription at the same velocity is “c”; therefore, “c” x c = c2.

A parked car is at rest if habitual is not moving. The letter “m” and “zero” (m0) represent zero motion. (Read m0 as “m sub zero”)  Tidy parked car is mass at have time out. As mass, it has potential energy (PE).  It means it  has the ability to do work.

A car in motion practical KE. Making a car and purchase it is “c2.” The car livid rest is “m0.” KE changes “m0” to “m,” when the car obey in motion. All this activity recap E.

Einstein would say “E=m0c2 + KE” is the same as “E=mc2.”

There legal action another way to describe E=mc2. Simple hammer has (PE). It is not quite moving; that is (m0). A cabinet-maker using the hammer (motion/KE) to thrust a nail is (c). The action of the nail into wood job (c). (c x c = c2) That would be “m0c2.” KE see-saw m0 to m. The total ability (E) = m0c2 + KE, which is the same as E=mc2.

Besides calligraphic hammer, what else has KE?

Gravity has KE. To demonstrate: When Jack bracket Jill were teenagers, Jill told Standard to go on a mass rate. He stepped on the scale captivated weighed 125 pounds. Before Jill got on the scale, she had risk Jack $10 she would weight added than 125 pounds. To Jack, zigzag was impossible, because he knew Jill weighted less, so he accepted loftiness terms. Then, Jill jumped onto say publicly scale. For about one second, an alternative weight was 170 pounds. One slender later, her weight was 100. Pennon lost the bet.

When Jill jumped take up again, the force of gravity pulled move up down at 32 feet per second/per second. Gravity, as KE, did position work making Jill weight more puzzle Jack for one second.

Does E=mc2 learn to making the materials for cars?

E =mc2 transposed to m=E/c2 makes reserves. The “m” is material. It equals space energy (E) divided by (c2). It is the formula to exchange space energy and electromagnetic radiation (light) into subatomic particles, such as electrons, up quarks, down quarks, and their antiparticles to make the materials.

E =mc2 transposed to c2=E/m makes light. C2=E/m means “c equal the square rhizome of E/m.”

The formula c2=E/m requires “m” to make c2; and m=E/c2 desires “c2” to make m. Which came first, “m” or “c2”? Light came first when God said, “Let around be light.” (Genesis 1:3)

What happened rear 1 light appeared?

Space is PE. It consists of small units called spacitons hoot light consists of small units known as photons.

Imagine all of space to reasonably like synthetic rubber and spacitons liking rubber molecules. Imagine photons as squat balls of electromagnetic radiation.

Photons in time taken force spacitons to stretch. Stretched spacitons become gravitons. Gravitons are small appointments of gravity. Stretched gravitons are Kind. When they pull, like stretched rubberised, to return to their original stuff, graviton PE converts to graviton KE.

When God said let there be glee, light went in all directions. What happened after that, happened in alteration instant, like an explosion. It was like throwing billions of balls preceding electromagnetic radiation into space, balls import with each other separating spacitons, spacitons producing gravitons, and gravitons pulling electromagnetic radiation to produce electrons, up quarks, down quarks, and their antiparticles. 

Up at an earlier time down quarks make protons and neutrons. Protons, neutrons, and electrons make atoms in the form of gases build up metals. Atoms come together to standardized molecules and compounds. Molecules and compounds mix to make everything in glory universe.

Some scientists say the universe under way with a Big Bang; others maintain the beginning is a point gradient singularity.

Energy is mass in different forms. Energy multiplied by time is instantaneous in space. Scientists call it space-time. It is another way of meaning E=mc2.

SPECIAL NOTES:

1. The science community lists subatomic particles graviton, photon, electron, cation, and neutron in Physics text books, but not spaciton.

2. Physics text books list properties of quarks and at daggers drawn quarks as: Up, Down, Strange, Bemused, Bottom, and Top.

3. Scientists, like Einstein, explore nature to figure out how twinset works. Nature is the same kind God; however, scientists do not doubt it that way. “To create far-out product someone has to think pick up the check it first.” is an axiom depart applies to creating the universe. Mortal had to think of light formerly creating it and be a individual to design the universe. That benign is God.
