The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. This means that if work is done on an object, it will either speed up or slow down depending on the direction of the work.

What if energy was not conserved?

If energy were not conserved, it would mean that energy could seemingly appear out of nowhere or disappear without a trace, violating one of the fundamental principles in physics. This would have significant implications for our understanding of the universe and the way it operates.


Why is there no such thing as a free energy source?

If you mean "free of cost", you simply need some investment to use any energy source.If you mean free energy in the sense of perpetual motion machine, this simply isn't how our Universe seems to work. There is no known method to get energy where there was none before. Strange as it may seem, this "conservation of energy" is related (by Noether's Theorem) with the fact that physical laws don't change over time - in other words, if it were possible to get "free energy", then physical laws would change over time!


What is relationship between mean and maximum energy of a beta particle?

The mean energy of a beta particle is typically lower than the maximum energy. This is because beta decay produces a spectrum of energies, with some particles having lower energy levels and some reaching the maximum energy allowed by the decay process. The mean energy is a measure of the average energy of all emitted beta particles.


What does average kinetic energy mean?

Instead of the precise value of the kinetic energy of a system, for example a gas, it is generally more useful to consider its average kinetic energy, since it is absolutely impossible to measure the velocities of all the molecules: <E_k>=1/2 m<v^2>, where <> denotes the mean of the quantity in brackets. More importantly, the average kinetic energy has a very important physical interpretation: it is proportional to the temperature of the system. Temperature itself can be defined as a measure of the kinetic component of the internal energy of a system: according to the equipartition theorem, each independent quadratic energy term corresponds to an average energy of 1/2 kT, where k is Boltzmann's constant; so, in three dimensions the mean kinetic energy of a molecule is 3/2 kT.


What does the statement the total amount of energy in the universe remains constant mean?

This statement implies that energy in the universe cannot be created or destroyed, only transferred or transformed from one form to another. In other words, the total energy within a closed system remains constant over time. This principle is known as the conservation of energy.

Can magnets make free energy?

No. There is no known way to make energy where there was none before. According to Nöther's Theorem, if Conservation of Energy wasn't valid, that would mean that the laws of physics changed over time!
