How is Albert Einstein's equation Emc2 important today?
The equation, E = mc2, is important today because it is the basic equation of nuclear physics. So for example it is used to calculate the amount of energy produced by the fuel in a nuclear power station, or the amount of energy potentially released in a hydrogen bomb. It is also important is astrophysical models of stars, where energy is provided by nuclear fusion. The equation is used alot in particle physics to calculate the masses of particles produced and to calculate the the energy needed to produce particular particles.
Does inertia change with speed?
Inertia is a measurement of the amount of energy needed either to start the object moving, or to slow down or stop its movement. This depends upon the mass (weight) of the object, but more particularly its change of speed. The greater the mass (weight) of the object the greater the amount of energy needed to move it and stop it.
How does moving fulcrum on a lever change the amount of force needed to move an object?
how does moving a fulcrum on a lever change the amount of force needed to move an object
What is needed for matter to change states?
heat energy
What best defines the ionization energy of an element?
The amount of energy needed to remove the outermost electron.
What is needed to create change in a system?
The amount of energy is used to make the change.
What is the name of heat energy that changes ice into water and water into steam?
Latent heat is the measurement of energy needed to change the state of a substance at its melting point or boiling point. The latent heat of fusion of water is the amount of energy needed to change a fixed amount of water from a solid to liquid at 0 degrees C. this works out to be more than 800KJ of heat energy. The latent heat of vaporization of water is the amount of energy needed to change a fixed amount of water from a liquid to a gas at 100 degrees C. this is more than 1200KJ of heat needed to be absorbed.
What is the amount of energy needed to raise the temperature of 1kg of water by 1 degree Celsius?
phase change
What do you call the amount of energy needed to change a material from the solid state to the liquid state?
either potential or kinetic
What must be strong to in order to cause a chemical change to take place?
A sufficient amount of activation energy is needed.
The amount of energy needed to move an electron from one energy level to another is an?
The amount of energy needed to move an electron from one energy level to another is called a quantum.

The amount of useable energy decreases when?
The quality of energy decreases when you use it due to the second law of thermodynamics. Essentially, the energy spent from various reactions is processed, which reduces the amount of work needed to extract it.

Can a decimal be a coefficient in a chemical equation?
No! You can change coefficients as needed to balance an equation but you cannot just change a substance's subscripts.
It refers to the amount of energy needed to start the reaction?
Activation energy
What does the activation energy for a reaction represent?
Activation energy is the amount of energy needed to start a reaction.
