A force-time graph can be used to identify the impulse of an object because it is the product of force and time. Since impulse is also equal to the change in momentum, the graph can also be used to find the momentum as well as the velocity, if the mass of the object is given. Wh...
The impulse is defined as the force that is applied to the object for a very short duration. It can also be defined as the change in the momentum of the object. The mathematical formula of the impulse is given by the produ...
What data do I need to plot a kinetic energy vs. time graph? Does applied force cause acceleration? How is force related to momentum? How to calculate force from momentum? The force on a particle is directed along an x-axis and given by F = F0(x/x0 - 1) where x is in meters ...
This app shows the calculation of the final velocity of a body after it made contact with a variable force taking as reference the initial velocity, mass and the graph of the variation of F as a function of time. Made with native maple syntax (use of promt) and embedded components. In...

where O(t) are all terms that vanish at late time, from this point forward we ignore them. From Eqs. (9) and (18) we find the Lagrangian as, L=1−r2f(r)v2+f(r)r2ξ′2(r), (19) and from Eq. (19) the energy–momentum current is written as, Π1=∂L∂ξ′=ξ′...
Use the impulse of the force to find the change in momentum; find the jumper’s velocity at take-off to estimate the jump height. Use the flight time and kinematics to find the jump height. From the force vs. time graph, determine an acceleration vs. time graph. Integrate to find veloc...
In a turbulent flow the drag force is proportional to the momentum change of the fluid, which, in turn, is proportional to the mass of fluid whose velocity is changed in a unit time and to the velocity change of the mass. Therefore, we have: F~(πρr2v)(v) or F~πρr2v2 It is...
L = mh is a constant, and the angular momentum is constant. The position vector r with respect to the central force covers equal areas in equal time periods; thus, having a constant arealvelocity. In the following graph, in a small time interval dt, the radius r covers an area of dA...
I=FΔt, where F is the force and Δt is the time for which it acted.Answer and Explanation: The impulse delivered by the net force acting on an object is equal to the change in the momentum of the object. I=Δp, where......
