Learn how momentum and impulse are related to force and mass in motion. Explore examples of impulse in space, aircraft and engines, and how to calculate specific impulse.
- I as well am not really understanding what impulse is exactly.so.... if you want to change the momentum of an object, you have to apply a force. OK?? But if you apply that force for a long time then the moment...
- the problem in the paragraph momentum in space , i dont think the acceleration should be 9.8 ms^-2 c...The first part of the question requires us to find out how much impulse the astronaut is *capable* of applying which depends on how strong she is....
- So from what I understand, Impulse is change in momentum but it is a bit different. For instance Acc...Yes! That's entirely correct. Impulse is a certain amount of force you apply for a certain amount of time to cause a change in momentum. That is wh...
- what is the difference between force and thrust?They are different things thrust is a type of force but they do share the same units this is because force is a general term whil thrust is a subse...
- Hi, what are some of the most important everyday uses of momentum? I mean how can I benefit from my ...I think airbag is one of of it . Force and time is inversely proportional in momentum calculation so if time is increased, force is decreased. The...
- Hello. In the "Impulse of an aircraft", it says that the aircraft "can produce a thrust force of up ...If the force is constant at 250 for 30 s then taking the area under the curve IS multiplying 250 * 30. But if the force is not constant then you ca...
- for that equation in specific impulse, does it mean that the specific impulse equals momentum/weight...The specific impulse equals the change of momentum over the weight of fuel.
Learn how impulse and momentum are related to force and motion, and how to use the impulse-momentum theorem to solve problems. Explore examples of impulse in sports, accidents, and engineering applications.

These concepts are merely an outgrowth of Newton's second law as discussed in an earlier unit. Newton's second law (Fnet = m • a) stated that the acceleration of an object is directly proportional to the net force acting upon the object and inversely proportional to the mass of the object. When combined with the definition of acceleration (a = chan...
If both sides of the above equation are multiplied by the quantity t, a new equation results. This equation represents one of two primary principles to be used in the analysis of collisions during this unit. 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...
Now consider a collision of a tennis ball with a wall. Depending on the physical properties of the ball and wall, the speed at which the ball rebounds from the wall upon colliding with it will vary. The diagrams below depict the changes in velocity of the same ball. For each representation (vector diagram, velocity-time graph, and ticker tape patte...
In the International System of Units, these are kg ⋅ m/s = N ⋅ s. In English engineering units, they are slug ⋅ ft/s = lbf ⋅ s . The term "impulse" is also used to refer to a fast-acting force or impact. This type of impulse is often idealized so that the change in momentum produced by the force happens with no change in time.

Feb 20, 2022 · Define impulse. Describe effects of impulses in everyday life. Determine the average effective force using graphical representation. Calculate average force and impulse given mass, velocity, and time. The effect of a force on an object depends on how long it acts, as well as how great the force is.
There are two crucial concepts in the impulse-momentum theorem: Impulse is a vector quantity; an impulse of, say, − (10 N · s) i ^ − (10 N · s) i ^ is very different from an impulse of + (10 N · s) i ^ + (10 N · s) i ^; they cause completely opposite changes of momentum. An impulse does not cause momentum; rather, it causes a change in ...
