# What is the definition of linear momentum?

Linear momentum is a vector quantity defined as the product of an object's mass, m, and its velocity, v. Linear momentum is denoted by the letter p and is called “momentum” for short: Note that a body's momentum is always in the same direction as its velocity vector. The units of momentum are kg. · m/s.

Thereof, what is the principle of conservation of linear momentum?

It is called the principle of linear momentum, or balance of linear momentum. If there are no forces applied to a system, the total momentum of the system remains constant; the law in this case is known as the law of conservation of (linear) momentum.

What does it mean for linear momentum to be conserved?

Such a situation implies that the rate of change of the total momentum of a system does not change, meaning this quantity is constant, and proving the principle of the conservation of linear momentum: When there is no net external force acting on a system of particles the total momentum of the system is conserved.

What is the definition of the law of conservation of momentum?

conservation of momentum. A conservation law stating that the total linear momentum of a closed system remains constant through time, regardless of other possible changes within the system.
