# Inertia velocity and momentum relationship

### How it works - Momentum - Momentum and Inertia, Mass and Weight, Velocity and Speed

Like inertia, the momentum of an on its mass. Unlike inertia, however, momentum takes In this formula, p stands for momentum, m for mass, and v for. Inertia is the property of mass that resists change. The difference is that he extended the time of his momentum change thus decreasing the force of the. How is it calculated and what is its relation to momentum? . Both momentum and inertia are a directly related to an objects mass (Except in.

Momentum can be calculated by multiplying the mass of an object by its forward velocity. If you increase either mass or velocity, the momentum of the object increases proportionally.

If you double the mass or velocity you double the momentum.

If you halve the mass or velocity you halve the momentum Impulse: At constant velocity the momentum of an object remains constant but if that object comes in contact with another object there is a change in momentum acceleration or deceleration that is related to the time of contact.

This relationship is called impulse.

The longer it takes to change the momentum, the less force is exerted on an object and vice-a-versa. If the breaks are applied gently, the momentum of the car is changed gradually over a long period of time and the force on you the passenger is slight.

We combine these three things into a single parameter for each object called its Momentum. The resistance to change of motion does not depend upon direction, so it is what we call a "scalar" quantity, and has been named Mass. We quantify Mass using units such as kg or lb-mass.

Objects that require a lot of Force to accelerate a little bit have large Mass. Objects that accelerate a lot with a little bit of Force have small Mass.

Speed is also a scalar quantity, but when we combine speed with direction, we get a "vector" quantity called Velocity. Momentum has both a magnitude and a direction.

We quantify the Momentum of an object as the product of the Mass scalar quantity times its Velocity vector. Velocity and Speed Not only is momentum often confused with inertia, and mass with weight, but in the everyday world the concepts of velocity and speed tend to be blurred.

Speed is the rate at which the position of an object changes over a given period of time, expressed in terms such as "50 MPH. Velocity, by contrast, is a vector.

If one were to say "50 miles per hour toward the northeast," this would be an expression of velocity. Vectors are typically designated in bold, without italics; thus velocity is typically abbreviated v. Scalars, on the other hand, are rendered in italics. Hence, the formula for momentum is usually shown as m v.

Linear Momentum and Its Conservation Momentum itself is sometimes designated as p. It should be stressed that the form of momentum discussed here is strictly linear, or straight-line, momentum, in contrast to angular momentum, more properly discussed within the framework of rotational motion. Both angular and linear momentum abide by what are known as conservation laws.
