(1) Kinetic energy in the classical sense = 1/2mv^2. What is the T expression in terms of momentum?

(1) Momentum (p) = mv p/m = v Substitute into equation we know and get kinetic energy = p^2/2m. This is the 1D equation. The 3D equation is T = 1/2m(p^2x + p^2y + p^2z) More test answers on https://studyhippo.com/physical-chemistry-3-schrodinger-equation/

What is Momentum?

Momentum is a term used in physics to describe the inertia of a moving object. It is the product of an object’s mass and velocity, so that a large mass moving at a slow speed will have more momentum than a small mass moving at a fast speed. Momentum can also be thought of as the impetus or driving force behind an object’s movement.The concept of momentum applies to many different things in everyday life. For example, when someone starts running they have to build up their momentum; if they stop abruptly, they will find it hard to start again. The same can be said for many other activities, such as getting started on an important project or task, studying for an exam, or becoming involved in something new. It takes effort and dedication to build up enough momentum to ensure success.In business and economics, momentum is often used as an indicator of investor confidence in a particular stock or industry sector. When there is strong momentum behind a stock it usually indicates that investors believe it will continue to rise in value; conversely when there is weak momentum it usually indicates that investors are less confident about its future prospects. Momentum investing involves buying stocks that are currently increasing in value and selling them before they start falling again; this strategy has been employed by some of the most successful investors throughout history.In sports too, having good momentum can make all the difference between winning and losing. Teams with good momentum tend to perform better than those without; this could be due to increased motivation levels or simply having more energy during games due to having won recent matches which have boosted morale within the team camp Overall then, understanding how you can use the concept of momentum in your own life can be very useful; whether you’re trying to get started on something important or just looking for ways to improve your performance at work or school – having good ˜momentum’ behind you could be just what you need.
