Applications of Impulse-Momentum Change Theorem
The sports announcer says, "Going into the all-star break, the Chicago White Sox have the momentum." The headlines declare "Chicago Bulls Gaining Momentum." The coach pumps up his team at half-time, saying "You have the momentum; the critical need is that you use that momentum and bury them in this third quarter."
Momentum is a commonly used term in sports. A team that has the momentum is on the move and is going to take some effort to stop. A team that has a lot of momentum is really on the move and is going to be hard to stop. Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum.
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
Momentum = mass • velocity
In physics, the symbol for the quantity momentum is the lower case p. Thus, the above equation can be rewritten as
p = m • v
where m is the mass and v is the velocity. The equation illustrates that momentum is directly proportional to an object's mass and directly proportional to the object's velocity.
The units for momentum would be mass units times velocity units. The standard metric unit of momentum is the kg•m/s. While the kg•m/s is the standard metric unit of momentum, there are a variety of other units that are acceptable (though not conventional) units of momentum. Examples include kg•mi/hr, kg•km/hr, and g•cm/s. In each of these examples, a mass unit is multiplied by a velocity unit to provide a momentum unit. This is consistent with the equation for momentum

hope it helps u
make me as a brain list plz,✌️
Explanation:
Modern-day Patna, originally built by Shishunaga dynasty’s Ajatashatru, in 490 BC as a small fort (Pataligrama) near the River Ganges and later the capital of the ancient Mahajanapadas kingdom of Magadha.
Its key central location in north central India led rulers of successive dynasties to base their administrative capital here, from the Nandas, Mau’ryans, Sungas and the Guptas down to the Palas.
In the Lord Buddha’s day it was a village known as Pataligarma. He visited it shortly before his death and prophesied it would be great but would face destruction either by fire, water, or civil war. Two important councils were held here, the first at the death of the Buddha and the second in the reign of Asoka.
During the reign of Emperor Asoka in the 3rd century BC, it was the world’s largest city, with a population of 150,000-300,000. Patliputra reached the pinnacle of prosperity when it was the capital of the great Mauryan kings, Chandragupta Maurya and Ashoka the Great.
