The formula for kinetic energy?
0.5mv2. For relativistic speeds, a more complicated formula must be used.
Is an object in travel more dense than when stationary?
Gee whiz, I guess it would be. I never thought of that. When an object is moving, its length in the direction of motion decreases ... which decreases its volume ... and its mass increases. So its relativistic mass/relativistic volume is greater than its rest-mass/rest-volume .
What happens when every day speeds are put into the relativistic equations?
The solutions will be extremely similar to what you would get for equations in Newtonian physics. At everyday speeds the deviation from Newtonian mechanics is negligible.
Is emc2 correct?
It is not the entire equation, but for current practical purposes, it is correct. If an object is moving at relativistic speeds, it is not correct. It requires you use relativistic mass, which is based on the velocity relative to the speed of light. It is correct for any human purposes.
How kinetic energy of an object changes when the speed of an abject doubles?
Assuming non-relativistic speeds: Doubling the speed will quadruple the kinetic energy.
Why are Einstein relativistic results not found in your daily life?
At the speeds encountered in everyday life the deviation of special relativity from so-called everyday "Newtonian" physics is negligible. Relativistic effects only become worth considering when speeds reach a significant fraction of the speed of light or if you are in need of extraordinary precision. Even at the speeds of planetary orbits Newtonian calculations are highly accurate, so it is unnecessary to use the more complicated equations of relativity.
What is the mass of a 3.5 kg radio designed for space travel that is in orbit?
3.5 kg. Barring relativistic considerations, mass is constant. Since you have stated the mass to one significant figure, relativistic considerations are too tiny at orbital speeds or from gravitational differences to be taken into account.
Is kinetic energy a form of energy in the earth's system?
No, not at all. Kinetic energy is energy related to movement - any moving object has kinetic energy; at low (non-relativistic) speeds, the kinetic energy is calculated as 0.5 x mass x velocity squared.No, not at all.

What is the energy of a moving electron?
In the absence of electric, magnetic and gravitational fields or potentials it would be its kinetic energy mv2/2. This is an approximate formula for "low" speeds, but at very high ("relativistic") speeds it is (m - m0)c2 where c is the velocity of light and the first factor is the difference between the mass and the rest mass. At low speeds both values agree.
What is the formula for getting kenetic enegry?
KE = (1/2) mv2, that is, 1/2 times the mass times the speed squared. For very high(relativistic) speeds, a more complicated formula is used.
Would increasing the speed of an object increase or decrease its kinetic enregy?
More speed means more kinetic energy.More specifically, the kinetic energy is proportional to the square of the speed. (This is for non-relativistic speeds.)
What was the big bang and what were conditions an occurrence?
The big bang was a cosmic explosion in which the universe was created. Temperatures were so high that random motions of particles were at relativistic speeds and that the only matter that could exist in such conditions was antimatter.
