Linear momentum | AP®︎/College Physics 1 | Science | Khan Academy
Relate the concepts of momentum, impulse, force, and time through graphs and calculations, and use these relationships to predict the motion of objects in a system. Apply Newton's third law to determine the conditions under which a system's momentum is conserved. Investigate how different collision types affect a system's momentum and kinetic energy. Use the concept of center of mass to simplify the analysis of a system's motion.
