Conditions of Newton’s First Laws
The absence of a net external force: If the net external force acting on an object is zero, the object will remain at rest or in motion with a constant. This means that if an object is already in motion, it will continue moving in the same direction and with the same speed, and if it is at rest, it will remain at rest. This condition is fundamental to understanding the behavior of objects in motion and the effect of forces on their motion.
Inertial reference frame: The observation of the object’s motion must be made from an inertial reference frame, which is a frame of reference that is not accelerating. An inertial reference frame is a reference frame that is either at rest or moving with a constant velocity relative to other reference frames. The use of an inertial reference frame ensures that the observation of the object’s motion is consistent and not affected by the motion of the observer. If the observer is not in an inertial reference frame, then the observation of the object’s motion will be distorted by the observer’s motion.
Newton’s First Law of Motion
Newton’s First Law of Motion: Newton’s First Law of Motion states that a body always opposes its change in the state of motion. Newton’s Laws of Motion were first proposed by Sir Isaac Newton in the late 17th century. Newton’s First Law of Motion finds its importance in various other laws and it is one of the fundamental laws of physics. It also finds its importance in various real-life examples.
In this article, we will learn about Newton’s First Law of Motion, its examples, real-life applications of Newton’s First Law of Motion, Newton’s First Law of Motion equations, and some practice problems on Newton’s First Law of Motion.
