*In this segment we define the terms momentum and impulse.*

## We apologize for the inconvenience...

An object that has a small mass and an object that has a large mass have the same momentum. Which object has the largest kinetic energy? An object that has a small mass and an object that has a large mass have the same kinetic energy. Which mass has the largest momentum? Professional Application. Football coaches advise players to block, hit, and tackle with their feet on the ground rather than by leaping through the air.

The concepts of Impulse and Momentum provide a third method of solving kinetics problems in dynamics. Generally this method is called the Impulse-Momentum Method , and it can be boiled down to the idea that the impulse exerted on a body over a given time will be equal to the change in that body's momentum. In a rigid body we will be concerned with not only linear impulse and momentum, but also angular impulse and momentum. The linear and angular impulse momentum equations are below, with the new term for angular impulse K starting out angular impulse momentum equation. For two dimensional problems, we can break the linear impulse equation down into two scalar components to solve. In this case, we simply need to break all forces and velocities into x and y components. Since all rotation will be about the z-axis for planar problems, the angular impulse momentum equation remains a single equation.

## Impulse and Momentum

Momentum can be defined as "mass in motion. In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity. Momentum is a vector quantity. As discussed in an earlier unit, a vector quantity is a quantity that is fully described by both magnitude and direction.

The activity will take place in the classroom. You will answer questions based on the lab activity as well as the concepts used in the lab activity. You will get two attempts to answer the lab activity questions and your mark will be the average of the two attempts. Ray of frost 5e. Like the law of conservation of linear momentum, the law of conservation of angular momentum is a fundamental law of physics, equally valid for relativistic and quantum systems. Momentum is inertia in motion. It is the product of an object's mass and its velocity.

## Segment A: Momentum and Impulse

In this section we are going to look at momentum when two objects interact with each other and, specifically, treat both objects as one system. To do this properly we first need to define what we mean we talk about a system, then we need to look at what happens to momentum overall and we will explore the applications of momentum in these interactions. For example, earlier we looked at what happens when a ball bounces off a wall. The system that we were studying was just the wall and the ball. The wall must be connected to the Earth and something must have thrown or hit the ball but we ignore those.

Choose the one alternative that best completes the statement or answers the question. They are thrown with equal speed against a wall. The ball bounces back with nearly the same speed with which it hit.

Пожилой человек отстранился. Танкадо посмотрел на женщину, поднеся исковерканные пальцы прямо к ее лицу, как бы умоляя понять. Кольцо снова блеснуло на солнце. Женщина отвернулась. Танкадо, задыхаясь и не в силах произнести ни звука, в последней отчаянной надежде посмотрел на тучного господина.

*Она подошла к окну, вертя бумагу перед глазами, чтобы найти лучший угол для падения лунного света. - Мидж… пошли. Это личный кабинет директора.*
