4.1 Fixed target and colliding beam experiments: Lab and CM frames Experimental setups for carrying out scattering experiments are of two types: (1) fixed target, where a beam of particles strikes particles at rest and (2) colliding beams, where counterrotating beam particles strike one another head on.

Notes on Elastic and Inelastic Collisions In any collision of 2 bodies, their net momentum is conserved. That is, the net momentum vector of the bodies just after the collision is the same as it was just before the collision,

The most general case of a completely inelastic collision is two particles m 1 and m 2 moving at an angle of θ 1 to each other with velocities v 1 and v 2, respectively. They undergo a completely inelastic collision, and form a single mass M with velocity v f, as shown below. 4.1 Fixed target and colliding beam experiments: Lab and CM frames Experimental setups for carrying out scattering experiments are of two types: (1) fixed target, where a beam of particles strikes particles at rest and (2) colliding beams, where counterrotating beam particles strike one another head on. 9.2 The Center of Mass The center of mass of a system of particles is the point that moves as though: (1) all of the system’s mass were concentrated there; (2) all external forces were applied there. The center of mass (black dot) of a baseball bat flipped into the air follows a parabolic path, but all other points of the

Now you decide to go back and pick on some poor light cars in a monster bumper car. What happens if your bumper car (plus driver) has a mass of 400 kilograms and you rear-end a stationary 300-kilogram car? In this case, you use the equation for conservation of kinetic energy, the same formula you use in the previous example. Collisions and Scattering Theory 1Two-ParticleCollisions in the LAB Frame Consider the collision of two particles (labeled 1 and 2) of massesm 1 and m 2,respectively. Let us denotethevelocities of particles 1and2before the collisionas u 1 and u 2,respectively, while the velocities after the collision are denoted v 1 and v 2.Furthermore, the ...
