What is impulse in a time graph?
In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object. If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J : Momentum is a vector quantity, so impulse is also a vector quantity.
Learn how momentum and impulse are related to force and mass in motion. See how impulse is used to calculate the motion of objects in space and aircraft, and what is specific impulse.
- 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 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....
- 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...
- 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...
- 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...
- 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...
- The specific impulse equals the change of momentum over the weight of fuel.
Impulse is the effect of a net force acting on an object for a certain time. Momentum is the resistance to stopping of an object. Learn the impulse-momentum theorem, units, and related concepts of dynamics.
From the equation, we see that the impulse equals the average net external force multiplied by the time this force acts. It is equal to the change in momentum. The effect of a force on an object depends on how long it acts, as well as the strength of the force. Impulse is a useful concept because it quantifies the effect of a force.
Impulse is the area under the curve of the force vs. time graph. Areas above the time axis are positive Δ p and areas below the axis are negative Δ p . If the force is not constant, we can divide the graph into sections and add up the impulse in each section.
- You gotta be careful with the terms "velocity" and "speed". Speed is the absolute value of the velocity. In the questions, the velocity is decreasi...
- No, the force does not change. The force is constant during those 0.55 seconds. The force is equal to the change in momentum over the change in tim...
- "When the force is not constant" "For a constant force" reread that please
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.
