View the content: Collisions of Point Masses in Two Dimensions

 Name: Collisions of Point Masses in Two Dimensions ID: m42165 Language: English (en) Summary: Discuss two dimensional collisions as an extension of one dimensional analysis. Define point masses. Derive an expression for conservation of momentum along x-axis and y-axis. Describe elastic collisions of two objects with equal mass. Determine the magnitude and direction of the final velocity given initial velocity, and scattering angle.
