Science is real. Science is cool. Science uses a lot of terms that we all think we know. But, do we really know what we are talking about? In the spirit of scientific community and understanding, let's clear up one big scientific misconception that we all get wrong Words related to momentum energy , power , strength , drive , force , impulse , propulsion , thrust.

The Economics of Sports Gambling Ep. Dubner August 20, Freakonomics. The Wave Algernon Blackwood. To this product physicists assign the term "vis viva," or living force. It would be deemed an exaggeration to state that of the popular articles written on the subject of mechanics, not one in ten uses the word " momentum" correctly ; yet perhaps it will be believed, when so well known a writer on scientific subjects as Professor Silliman, of Yale, in a recent work, falls into the same error, as is evidenced by the following quotation: "It is a fundamental principle of mechanics that the same force, acting upon different bodies, imparts velocities in the inverse ratio of the quantities of matter.

The same force, acting upon different bodies, imparts velocities in the inverse ratio of the square roots of their quantities of matter. What, then, is momentum? Mass is the measure of the resistance which a body offers to a force brought to bear upon it! Velocity is the measure of the rapidity with which a body passes through space!

Vis viva is the measure of the power stored tip in a moving boely[! Has not momentum any such physical interpretation? I know of none ; know of it only as a conventional term, used bj' physicists to express a certain product, often occurring in mechanical analysis, but not susceptible of direct interpretation as a measure of any phenomenal action.

It has been the object of this article to point out facts rather than to prove their correctness. Those who feel suffi-cient interest in the matter to pursue it further will find in the issue of next week argument to prove that vis vira, not momentum, measures the amount of power stored up in a moving body. THE Arctic expedition of Dr. Hays has been heard from at Upernavik North Greenland ; all well. This expedition is fitted out for three years. Yet if the Mack truck were at rest, then the momentum of the least massive roller skate would be the greatest.

The momentum of any object that is at rest is 0. Objects at rest do not have momentum - they do not have any " mass in motion. The momentum equation can help us to think about how a change in one of the two variables might affect the momentum of an object. Consider a 0. The total mass of loaded cart is 1. If the cart was instead loaded with three 0. A doubling of the mass results in a doubling of the momentum. Similarly, if the 2. A quadrupling in velocity results in a quadrupling of the momentum.

Compare the velocities of these three players. How many times greater are the velocity of the halfback and the velocity of the tight end than the velocity of the lineman?
