How is the impulse-momentum change theory applied in the real-world?

Question

just need some examples of how its a real world application and how its used.

Answer 1

1. Padding of delicate articles in cushioning materials - this causes the decelerating force to be low, thus increasing the time in which the body is brought to rest from motion. (Impulse always remains constant in ANY case)
2. To catch a moving ball, one would follow the ball's movement with the hand after having made contact with it. (Same explanation as above)

Answer 2

Impulse Momentum Theorem Examples

Answer 3

In quality control you use probability every day. You have a machine making some kind of widget that has a dimension that must be held within certain tolerances. You take 25 parts and measure them, then do what's called a 'capability study' to see if the machine is able to get them all within limits, or if you need to use a better machine. Another place probability is used is in insurance. They have people called 'actuaries' who compile statistics to see what the probability is of someone dying in the next year, the next five years, ten years, etc. Someone who smokes is more likely to die. Or someone who takes antidepressant meds, or has a history of heart problems, etc. They figure out how each of these factors affects the person's probabilities, and they figure this into the rates. Big powerful corporations often sell products they know are not as safe as they could be. There was a famous case back in the 1970s with the Ford Pinto. Millions of these cars were sold with a defect that could cause the gas tank to explode if the car was hit from behind. After they found out about it, they did a probability analysis and found that it would be cheaper to just let it happen, and defend themselves against the resulting lawsuits, than to recall all the cars and fix the problem.

Answer 4

ft = impulse delP; where f is a net force and t is the period that force is applied. As f = ma, we have delP = mat = m[(v' - v)/t]t = mv' - mv = p' - p; where p' and p are two different instances of momentum (which is why I wrote impulse as delP). So, to answer your question, momentum change over time is used everywhere force is applied...momentum change over time is force.

For example: peeling rubber when the stop light goes green, hitting a baseball, hammering in a nail, turning a sharp corner on a bike, launching a rocket ship, throwing food in a food fight, weighing yourself on a bathroom scale, and on and on....

It might be easier to list examples of where momentum change is not applied.

Answer 5

Gun recoil is a classic example. Conserve momentum.
