# Linear Momentum Definition

### Also called linear momentum.

**Linear momentum definition**.
Fortunately the way that we use the word momentum in everyday life is consistent with the definition of momentum in physics.
Learn the definition of center of mass and learn how to calculate it.
If an apple is sitting in a glass elevator that is descending an outside observer looking into the elevator sees the apple moving so to that observer the apple has a non zero momentum.
Momentum is a measurable quantity and the measurement depends on the motion of the observer.

There is an almost linear relationship between people who smoke cigarettes and the occurrence of lung cancer meaning there is probably a strong correlation between the two. It is a conserved quantity. In mathematics a linear map also called a linear mapping linear transformation or in some contexts linear function is a mapping v w between two modules including vector spaces that preserves in the sense defined below the operations of addition and scalar multiplication. As was the case with velocity there are two kinds of acceleration average and instantaneous.

Average acceleration is measured over a long measurable time interval while instantaneous acceleration is measured over a very small infinitesimal time interval. A quantity expressing the motion of a body or system equal to the product of the mass of a body and its velocity and for a system equal to the vector sum of the products of mass and velocity of each particle in the system. 1 angular momentum is the product of angular velocity of a rotating body and its moment of inertia about the axis of rotation.

Momentum is a corner stone concept in physics.
