Collision in one dimension Student name: Partners’ name: Section: Date experiment done: Date lab report due: Objective To investigate conservation of energy in one dimensional analysis where two bodies are used to induce collisions. Theory In order to define momentum we must assume some mass and its velocity v here we can say that momentum p is given by the relation p=mv and we can thus write Newton’s 2nd law as F=ddtp in this case F is the net force on the mass m. In case F=0 this translate that p is equivalent to a constant which is expressed in Newton’s 1st law. In a system of particles we identify each particle with subscript ᵢ such that Fᵢ =ddt pᵢ. Summation on both sides of the equation give us ᵢ=1n Fᵢ=Fddtᵢ=1n pᵢ=ddtP where n is the number of particles whereas F is the net force on the system and incurred during experiment. During inelastic collision both kinetic energy and momentum are conserved during this little or no energy is lost to sound heat or deformation. Spring bumpers was used to reduce the friction. If disk magnets were used then the corresponding velocities would be high this because of force of attraction induced by the magnets. Energy is lost to sound heat and deformation in the inelastic collision. When gliders collide a sound is produced this sound is as result of energy lost and thus could contribute energy and momentum balance. Kinetic energy is high than sound wave energy since it is produced as result of loss in kinetic energy. Conclusion The aim of experiment was attained it was shown that energy and momentum are conserved though some energy is lost to sound heat and deformation. Friction and errors made experimental values to have some difference with theoretical values. [...]
