The video begins by introducing Newton's First Law of Motion, often called the law of inertia []. This fundamental principle explains that an object will continue in its current state of motion—whether at rest or moving in a straight line at a constant speed—unless an external force acts upon it []. A vivid example is provided of a bicycle rolling downhill; it will maintain its motion until an obstacle, like hitting something or applying brakes, intervenes to alter its course []. The speaker emphasizes that this behavior is universal, applying to all objects in the cosmos, regardless of whether they are stationary or in continuous linear movement, until an external influence disrupts that state [-].
