Impulse Momentum Formulation — Lesson 2

This lesson covers the concept of impulse momentum formulation, which is a different approach based on Newton's laws of motion. The lesson explains how a time-varying force acting over a certain period can cause a change in momentum. The instructor uses a scalar formulation of Newton's law to illustrate the idea and then introduces the concept of impulse, which is the integral of a time-varying force over a certain span of time. The lesson also includes a practical example of a block sliding up an inclined plane under the action of a time-varying force. The impulse momentum formulation is used here to calculate the time at which the block would acquire a certain velocity.
