What does write a unit rate mean

The initials PRN stand for the Latin phrase pro re nata, which means "as the situation demands. It's hard to plan your life or your budget around PRN work, unless you're the one who decides when and how often to work, but there are also benefits to working PRN.

Posted on April 7, by The Physicist Physicist: This famous equation is a little more subtle than it appears. Energy takes a heck of a lot of forms: For example, the energy stored in a not overly stretched or compressed spring is and the energy of the heat in an object is.

Now, these equations are true insofar as they work like all true equations in physics. However, neither of them are saying what energy is. Energy is a value that we can calculate by adding up the values for all of the various energy equations for springs, or heat, or whatever.

The useful thing about energy, and the only reason anyone ever even bothered to name it, is that energy is conserved. The individual terms may get bigger and smaller, but the total stays the same.

For example, the equation used to describe the energy of a swinging the pendulum is where the variables are mass, velocity, gravitational acceleration, and height of the pendulum. These two terms, the kinetic and gravitational-potential energies, are included because they change a lot speed and height change throughout every swing and because however much one changes, the other absorbs the difference and keeps E fixed.

Joule had to do all kinds of goofy experiments to demonstrate that, for example, the sum of gravitational potential energy and thermal energy stays constant. He had to build a machine that turned the energy of an elevated weight into heat, and then was careful to keep track of exactly how much of the first form of energy was lost and how much of the second was gained.

As the weight falls, it turns an agitator that heats the water. The sum of the two stayed constant. He did a few fancy things inincluding figuring out a better way of doing mechanics. Newtonian mechanics had some subtle inconsistencies that modern modern science was just beginning to notice. Special relativity helped fixed the heck out of that.

Among his other predictions, Einstein suggested with some solid, consistent-with-experiment, reasoning that the kinetic energy of a moving object should bewhere the variables here are mass, velocity, and the speed of light c.

This equation has since been tested to hell and back and it works. The approximation is good enough that ye natural philosophers of olde can be forgiven for not noticing the tiny error terms. Before Einstein, the kinetic energy of a completely stationary rock and a missing rock was the same zero.

After Einstein, the kinetic energy of a stationary rock and a missing rock were extremely different by mc2 in fact. So, energy is a sort of strict economy total never changes with many different currencies types of energy.

When you drain a battery it literally weighs a little less because of the loss of chemical energy. The total difference for a good D-battery is about 0.

About the only folks who regularly worry about the fact that energy and matter can be sometimes be exchanged are high-energy physicists. Cloud chamber tracks like these provided some of the earliest evidence of particle creation and have entertained aged nerds for decades.

So when particle physicists talk shop, they use energy rather than matter.

For those of us unbothered by creation and annihilationthe fact that rest-mass is a term included among many different energy terms is pretty unimportant. Nothing we do or experience day-to-day is affected by the fact that rest-mass has energy.
