- For any system, the impulse of a given force equals the amount of linear momentum transferred across the system boundary in the specified time interval. It does not always equal the change in linear momentum of the system. Frequently, it is impossible to directly measure the magnitude of the force as a function of time.

Momentum, Impulse, and the Impulse-Momentum Theorem. Linear momentum is the product of a system’s mass and its velocity. In equation form, linear momentum p is. p = mv. p = m v. You can see from the equation that momentum is directly proportional to the object’s mass ( m) and velocity ( v ).
Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p . By definition, p = m ⋅ v. Where m is the mass and v is the velocity. The standard units for momentum are kg ⋅ m / s , and momentum is always a vector quantity.
- 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...

- 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...

- 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.
. F dt = L ̇ dt = L2 − L1 = ΔL . t1 t1. (2) Here, L1 = L(t1) and L2 = L(t2). The term. t2. = I F dt = ΔL = (mv)2 − (mv)1, t1. is called the linear impulse. Thus, the linear impulse on a particle is equal to the linear momentum change ΔL. In many applications, the focus is on an impulse modeled as a large force acting over a small time. But.
The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. J = ∆p. If mass is constant, then… F∆t = m∆v. If mass is changing, then… F dt = m dv + v dm. The impulse-momentum theorem is logically equivalent to Newton's second law of motion (the force law). Units.

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...
