What is the mathematical equation for momentum?
p = m v . p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.
What is a example of momentum?
Momentum can be thought of as the “power” when a body is moving, meaning how much force it can have on another body. For example, a bowling ball (large mass) moving very slowly (low velocity) can have the same momentum as a baseball (small mass) that is thrown fast (high velocity).
How do you find momentum in Class 9?
The initial and final momentum of the object will be, p1 = mu and p2 = mv respectively. The change in momentum = m × (v – u). Here a = [(v – u)t ] is the acceleration, which is the rate of change of velocity.
Why is P used for momentum?
Clearly, were the letter “m” used, there might well be confusion with mass. The German word for momen- tum is der Impuls [sic] and the French is l’impulsion. Choosing “I” as its symbol would lead to confusion with moment of inertia and inertia. For this reason the Germans and French chose “p” for momentum.
How do you find final momentum?
The final momentum would be the mass of both balls times the final velocity, (4+6)(vf). We can solve for vf through conservation of momentum; the sum of the initial momentum values must equal the final momentum.
What is momentum Class 9 Example?
-A truck full of goods has a large mass and so it must slow down before a stop light because it has the large momentum with the same velocity and so it is very difficult to stop. -A moving bullet has a large momentum since it has an extremely large velocity though it carries very small mass.
What are some examples of momentum in sports?
As momentum is the product of mass and the velocity, you can increase momentum by increase either of these elements. In sport, examples include using a heavier bat or racket and increasing running speed or hand speed.
What is momentum class8?
Momentum is how we measure mass that is in motion. Any moving object will have momentum. Under the law of physics, the object’s momentum equals mass times velocity. Momentum = Mass x Velocity.
What is momentum in physics class 11?
Momentum: Momentum of the body is the quantity of motion possessed by it or the momentum of a body is the product of its mass and velocity.
