What is the formula for momentum?A:
Describe the momentum in a closed system. Is there a formula?A:
Momentum A is the property of an object that determines the amount of force required to change its motion. It is a vector quantity, meaning it has both magnitude and direction.
Force and momentum are different in that force is an external influence that causes a change in the momentum of an object, whereas momentum is the product of an object's mass and velocity. Force is measured in newtons, while momentum is measured in kilogram meters per second.
The formula for momentum is given by p = m*v, where p represents the momentum, m is the mass of the object, and v is its velocity. The unit of momentum is kilogram meters per second (kg m/s).
In a closed system, the total momentum remains constant if there are no external forces acting on the system. This is known as the law of conservation of momentum. The formula for the total momentum in a closed system is given by the sum of the individual momenta of all the objects in the system.
