Momentum is directly proportional to

Last updated on Apr 13,

This text goes into the concepts of linear momentum, impulse, and how force is used to change momentum over time. The scientific definition of linear momentum is consistent with most people's intuitive understanding of momentum: a large, fast-moving object has greater momentum than a smaller, slower object. Linear momentum is defined as the product of a system's mass multiplied by its velocity. In symbols, linear momentum is expressed as. Momentum is directly proportional to the object's mass and also its velocity. Thus the greater an object's mass or the greater its velocity, the greater its momentum. Momentum is a vector having the same direction as the velocity.

Using the example of football players, point out that both the mass and the velocity of an object are important considerations in determining the impact of collisions. The direction as well as the magnitude of velocity is very important. In equation form, linear momentum p is. A large, fast-moving object has greater momentum than a smaller, slower object. Momentum is a vector and has the same direction as velocity v. Since mass is a scalar , when velocity is in a negative direction i. Momentum is so important for understanding motion that it was called the quantity of motion by physicists such as Newton. Newton actually stated his second law of motion in terms of momentum: The net external force equals the change in momentum of a system divided by the time over which it changes. The change in momentum is the difference between the final and initial values of momentum. From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum. The effect of a force on an object depends on how long it acts, as well as the strength of the force. Impulse is a useful concept because it quantifies the effect of a force. A very large force acting for a short time can have a great effect on the momentum of an object, such as the force of a racket hitting a tennis ball.

Momentum p is a vector having the same direction as the velocity v. No information is given regarding direction, and so we can calculate only the magnitude of the momentum, p. As usual, a symbol that is in italics is a magnitude, whereas one that is italicized, boldfaced, and has an arrow is a vector. Although the ball has greater velocity, the player has a much greater mass. Thus the momentum of the player is much greater than the momentum of the football, as you might guess. We shall quantify what happens in such collisions in terms of momentum in later sections.

Confused between the two terms, momentum and force? Here, you will learn the relation between force and momentum and the crucial points of difference between them. Generally, momentum refers to the quantity that tells about the content motion present in any moving object. However, force refers to the amount that changes the amount of action present when acted upon any object. The amount of motion encompassed within a moving object refers to momentum.

Momentum is a commonly used term in sports. A team that has the momentum is on the move and is going to take some effort to stop. A team that has a lot of momentum is really on the move and is going to be hard to stop.

We will consider systems with varying mass in some detail; however, the relationship between momentum and force remains useful when mass is constant, such as in the following example.
