- 7.1: Linear Momentum
In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
The SI unit for momentum is kg m/s. Momentum is so important for understanding motion that it was called the quantity of motion by physicists such as Newton. Force influences momentum, and we can rearrange Newton’s second law of motion to show the relationship between force and momentum.
In general, we will refer to this type of momentum as linear momentum when we want to distinguish it from angular momentum. Note on units: force has SI units of Newtons, \(\textrm{N}\). Impulse must therefore have units of Newton seconds, \(\textrm{N}\cdot\textrm{s}\).
The linear momentum \(p\) of an object is the product of its mass and its velocity: \[\vec{p} = m \vec{v} \ldotp \label{9.1}\] As shown in Figure \(\PageIndex{1}\), momentum is a vector quantity (since velocity is).
16 Απρ 2023 · Linear momentum is a vector quantity. Linear momentum is represented by the letter p → and is often referred to as simply "momentum." The most commonly used metric unit for momentum is the kilogram*meter/second. The plural of momentum is momenta or momentums.
Learn how to define and calculate linear momentum, and how it relates to force and Newton's second law of motion. The SI unit for momentum is kg · m/s, and examples are given for objects with constant and varying mass.
