liikemääräksi
Liikemäärä, often translated as momentum, is a fundamental concept in physics. It is defined as the product of an object's mass and its velocity. Mathematically, it is represented by the equation p = mv, where p is the momentum, m is the mass, and v is the velocity. Momentum is a vector quantity, meaning it has both magnitude and direction. The direction of the momentum is the same as the direction of the velocity.
The concept of momentum is closely related to Newton's laws of motion. Newton's first law, the law
A crucial principle in physics is the conservation of momentum. This law states that in a closed
