Newton's Second Law: Dynamics

This lecture covers Newton's Second Law of Motion, explaining how an object in motion is affected by the forces acting upon it, leading to changes in its velocity. The law is expressed as F=ma, where F represents the force applied to the object, m is the object's mass, and a is its acceleration. Various examples are provided to illustrate the law's application, including scenarios of braking and turning. The lecture emphasizes the relationship between force, acceleration, and mass, highlighting that the sum of forces acting on a stationary object is zero. Additionally, it discusses the concept of reference frames and inertial systems, where the principle of inertia is valid.
