# Momentum – The Space Condition For Any Moving Body

Moments are a way of measuring time. In physics, a second is a term involving the total product of an external amount and the quantity of an internal amount, and so it renders the meaning of the word “moment” somewhat obscure. The best way to think of moments is as an imaginary construct. The concept of moments has been around since the first day that quantum mechanics was first proposed, but it was not until the late twentieth century that it came to be widely used in any serious manner. Quantum mechanics postulates that all events take place in discrete time slices called “phases.” Each moment can be thought of as a separate phase occurring in an instant.

Imagine you are standing on a beach at sunset with a pencil in your hand. You measure the distance between the two points on the shore by simply drawing a line across the center of the pencil. Now imagine that you remove the middle of the pencil in order to make it lie on top of the sand, at the same time stretching out the length of the line. Once you have done so, you will have discovered a new phase of measurement, the moment of zero time. Because the definition of a moment eludes attempts to give a precise formula, it is often referred to as the distance between the center of mass and the reference point, although this is not technically required.

Any moment can be thought of as being between the center of mass and the reference point, but some events are easier to measure than others. The simplest of these is the position of the center of mass, because it is very easy to determine. However, other events, like the orientation of an spinning ball, can be more difficult. The problem of the distance between the reference point and the center of mass can best be resolved by using a turning or oscillating device such as a turning mirror, or by employing a known turning speed and measuring the time it takes for it to turn.

Other times it is more convenient to use an instrument such as a tape measure or a dial to calculate moments. For example, many athletes find it useful to know just how much weight they can lift, especially if they are planning to lift a lot of weight for an upcoming competition. The spring balance formula is used to determine the moments of inertia, which is useful for athletes who lift a lot of weight in any given workout. The number of revolutions per minute can also be calculated by simply dividing the weight by the number of times the clock has been turned, and multiplying the result by the age of the athlete (the larger the load, the more the workout will take).

There are many other common formulas for moments, including ones based on the concept of angular momentum. This occurs when an object spins rapidly and loses its angular momentum, becoming more compact than it was before. This compactness gives it a particular momentum which it retains until it is given another chance to regain momentum, such as when it is hit by an object moving in the opposite direction. The formula is usually used to describe a turning effect, where the orientation of an object determines how it will move. For example, if you were to take a snapshot of yourself at various moments during your daily activity, you would see a different picture depending on whether you were facing east (looking directly at the sun) or facing west (looking at a dashboard clock).

Momentum, as defined here, is the total amount of force that a body exerts over a time period. It is important to note that it is not distance; what is termed as “pace” is actually the difference between the actual distance traveled (determined by the formula of moments) and the maximum distance traveled over a specific time period (also measured by the formula). A faster speed results in shorter moments. Thus, the athlete running the 100-meter dash in a record time may wind up using a much smaller and lighter spring than the runner who completes the same race but at a much slower speed. However, since the former athlete is utilizing a much larger mass for the same defined distance, the elasticity of his frame will give him the greatest amount of velocity that he can possibly have, while at the same time minimizing his potential momentum change.
