Momentum definition physics math. Momentum is a measurement of mass in motion. The definition of momentum in physics states that a particle might be considered to have momentum if its speed remains continuous since it is becoming accelerated. In a basic sense the more momentum a moving object has the harder it is to stop. Momentum is the most important quantity when it comes to handling collisions in physics.
Note the definition says velocity not speed so momentum is a vector quantity. Momenta is the product of the mass and velocity of an object. Momentum is defined as the quantity of motion of the body. In newtonian mechanics linear momentum translational momentum or simply momentum pl.
Momentum mass velocity. It is given as. It is measured by mass times velocity as momentum depends upon velocity and it depends on the direction of the motion of the body as well. Unit of momentum is given as.
If m is an object s mass and v is its velocity also a vector quantity then the object s momentum is. Momentum mass of the body times its velocity m omentum massof thebody itsvelocity. This means that a 1 000 kg car moving north at 20 m s has a different momentum from a 1 000 kg car moving south at 20 m s. Momentum is the quantity of motion of a moving body.
It is a vector quantity possessing a magnitude and a direction. Where m is the mass and v is the velocity. Momentum is a vector quantity since velocity is vector while mass is scalar. The equation illustrates that momentum is directly proportional to an object s mass and directly proportional to the object s velocity.
This is why you see the term used metaphorically like in the. The particle is traveling at the exact same speed because it is becoming accelerated. And the interaction does not need mass because light which has no mass can have momentum. Momentum is a physical quantity defined as the product of mass multiplied by velocity.
In physics the symbol for the quantity momentum is the lower case p. P m v. It is usually given the symbol. It is a wonderful and useful formula for normal every day use but when we look at the atomic scale things don t actually collide.
They interact from a distance through electro magnetic fields. Thus the above equation can be rewritten as. Momentum mass x velocity. This relationship can be described in the form of an equation.
Linear momentum is defined as the product of the mass m of an object and the velocity v of the object. P m v. Momentum is a corner stone concept in physics. Momentum is mass times velocity.
It is a conserved quantity that is within a closed system of interacting objects the total momentum of that system does not change value. This is also the essence of the meaning in physics though in physics we need to be much more precise. How much mass is in how much motion.
