Yet even in the most chaotic of collisions, as long as there are no net external forces acting on the colliding objects, one principle always holds and provides an excellent tool for understanding the collision. That principle is called the conservation of linear momentum which states thatThe total momentum of a system remains constant provided that no external resultant force acts on the systemFor two bodies colliding linearly, it is written mathematically as a vector equationTotal initial momentum = total final momentumm1.u1 + m2.u2 = m1.v1 + m2.v2If external forces (such as friction) are ignored, the total momentum of two carts prior to a collision (left side of the equation) is the same as the total momentum of the carts after the collision (right side of the equation).Collisions are classified into elastic (or perfectly elastic), inelastic and completely inelastic.There is also a concept of the kinetic energy of a moving body is stated mathematically by the following equation:KE1 = m1.v12Main Simulation ViewThe simulation has 2 collision carts on frictionless floor and wheels.SlidersExplore the sliders allows varying the variables. * mass of cart ONE, mass_1, m1 in kg * initial velocity of cart ONE, u1 in m/s * mass of cart TWO, mass_2, m2 in kg * initial velocity of cart TWO, u2 in m/sDrop Down MenuAllows for selecting what kind of collision is simulated.A Perfectly elastic collision is defined as one in which both conservations of momentum and conservation of kinetic energy are observedA Perfectly Inelastic collision is defined as one in which conservation of momentum is observed but the colliding carts stick together after the collision with kinetic energy lossDropDown Menushow: velocity, for visualizing the velocity vectorplot momentum vs time graph, for different representation of data for the momentum of cart 1, 2 and both.plot kinetic energy vs time graph, for different representation of data for the kinetic energy of cart 1, 2 and both.hint: COM, for the equation of conservation of momentumhint: COKE, or the equation of conservation of kinetic energyButtonsPlayStep ForwardResethave their usual meaning.Interesting FactThis simulation has real and ideal collision simulator targeted for A level Physics education.AcknowledgmentMy sincere gratitude for the tireless contributions of Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, Flix Jess Garcia Clemente, Anne Cox, Andrew Duffy, Todd Timberlake and many more in the Open Source Physics community.
