Impulse and Momentum summary

The video tutorial explores the dynamics of a balloon's velocity influenced by wind. It explains how Newton's laws apply to the balloon's motion, considering the net force as the vector sum of all forces acting on it. The concept of impulse, measured in Newton seconds, is introduced, along with momentum, defined as mass times velocity. The tutorial concludes by relating changes in momentum over time to the forces experienced by the balloon.
