Momentum is a commonly used
Momentum is a commonly used term in sports. When the announcer says, “The team is gaining its momentum!” it means that the team is on the move and is going to take some effort to stop. . A sports team that is on the move has the momentum. In other words If an object is in motion (on the move) then it has momentum.
Momentum is a commonly used term in sports. When the announcer says, “The team is gaining its momentum!” it means that the team is on the move and is going to take some effort to stop. . A sports team that is on the move has the momentum. In other words If an object is in motion (on the move) then it has momentum.
To stop such an object, it is necessary to apply a force against its motion for a given period of time. As the force acts upon the object for a given amount of time, the object's velocity is changed; and hence, the object's momentum is changed.
The change in momentum is called Impulse. The impulse experienced by the object equals the change in momentum of the object.
Now here is the equation form: F • t = m • Δ v
To truly understand the equation, it is important to understand its meaning in words. In words, it could be said that the force times the time equals the mass times the change in velocity. In physics, the quantity Force • time is known as impulse. And since the quantity m•v is the momentum, the quantity m•Δv must be the change in momentum. The equation really says that the: Impulse = Change in momentum
