Module 3: Waves and Thermodynamics


What is impulse?

In this post, we evaluate the effects of forces involved in collisions and other interactions and analyse quantitatively the interactions using the concept of impulse \Sigma p = \vec{F}_{net} \Sigma t , as a part of the Prelim Physics course under the module Dynamics and sub-part Momentum, Energy and Simple Systems. Impulse is the overall effect of a force acting over time, expressed in Newton-seconds.

The following two videos introduce you to the concept of impulse, and the related formula and theory-based around the forces involved in collisions and other interactions.
