Introduction to Momentum, Force, Newton's Second Law, Conservation of Linear Momentum, Physics

Подробнее о видео

This physics video tutorial provides a basic introduction into momentum. It explains how to calculate the average force exerted on object using Newton's 2nd Law of motion. In addition, it explains why the conservation of linear momentum occurs for every collision using newton's laws of motion and action reaction forces. Momentum is the product of mass and velocity. It's a vector quantity that contains both magnitude and direction. Force is defined as the rate of change of momentum per unit time. This video also contains an example problem that asks you to calculate the force exerted by a water hose given the speed of the fluid and the mass flow rate. This video provides all of the equations and formulas needed to solve all of the practice problems presented in this video.
