what is the physical significance of momentum? explain & dont give me the formula?

Answer 1

the physical significance of the momentum is that to know th impact of force, mass and velocity of the body

Answer 2

Well, it's mass times velocity. It's a measure of "wallop". Here are two contrasting examples to give you a "feel" for its physical significance:

1. A basketball and a bowling ball, each of the same size, roll down an alley at 40 mph. They each hit an object at the end of the alley. The bowling ball packs more of a wallop because it has greater mass.

2. Two identical baseballs are thrown at an object. One is a 100 mph fastball, and the other is a 40 mph lob. The fastball packs more of a wallop because of its much greater velocity, even though the masses of the two baseballs are equal.

Momentum is related to kinetic energy, KE = 1/2 mv^2. It's easy to grasp the notion, in the two examples above, that the object with the greater momentum also carries with it greater energy.

Answer 3

I'm not sure what you mean by "physical significance", but it's one of Newton's laws that says "An object in motion tends to stay in motion.."...that's momentum.
The object will stay in motion until some other force acts on it to change it rate and/or direction of motion. Larger objects have more momentum becuase of their greater mass. It takes a greater amount of force to get them moving in the first place. Therefore it takes a greater amount of force to alter their rate/direction of motion.
Example: If a VW Beetle is headed south at 50 mph and an 18 wheeler loaded with gravel is headed north at 50 mph....when they collide head on, the VW's momentum will easily be stopped by the 18 wheeler's momentum. The 18 wheeler will slow down but will keep moving north at a good pace because of it's large mass (and thus large momentum) in comparison to the VW.

Answer 4

in simple terms, momentum concept enables us to predict the out come when things collide, which one will move in what direction and at wad speeds, whether the "knocker" will bounce back or continue in the same direction and at wad speed etc. This cant be calculate simply by conservation of energy alone as u will not have any idea how much energy is transfered from the "knocker" to the "knocked", also, energy might not be conserved at all but loss as sound etc. therefore momentum is significance in that it shows the outcome of a collision

Answer 5

Imagine something hitting you with a speed of 3 lakh km/s !!!

Nothing happens - thats because there is zero momentum as weight of the body is zero ; that is photon - the light particle
Now imagine something 10 kg in mass & hits you with 3 km/sec;; you end up in ICU - momentum

No formulas as you said

Answer 6

Momentum is how much "ummmph" something has, consider it a measure or how hard it would be stop something, the more momentum it has, the harder to would be to stop. At the same speed a bowling ball would be harder to stop than a tennis ball since the bowling ball has more momentum. But if the tennis ball were goign a lot faster than the bowling ball, the tennis ball would be harder to stop (or would hurt more if it hit you)

Answer 7

Momentum is the quantification of inertia. Inertia is a general qualitative term referring to the tendency of masses to not change velocity unless forced. Momentum quantifies that and allows us to calculate the amount of force it takes to make those changes. This is given by Newton's second law that the force required is equal to the time rate of change of momentum.

Answer 8

in simple words, momentum is the quantity of motion contained in a body.the momentum of a body decides the motion.it depends on two factors, namely-mass and velocity.if the body has more mass but less velocity it will go on moving coz it will require more amt of force to stop. likewise if the body has lessser mass but more velocity, still more force will be required to cancel out the effect of velocity. hope all this helps.

I worked a lot on that one and i got this Momentum =$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

Answer 10

the physical significance is the product of the velocity and the mass can be lethal even if one of the two is insignificant
