Issac Newton was a mathematician and physicist who developed the principles of modern physics, including the laws of motion and is credited as one of the great minds of the 17th-century Scientific Revolution. During his work, he came up with the three basic ideas about the physics of most motion. He presented him in his book titled "Principia Mathematica Philosophiae Naturalis". The ideas have been tested and verified so many times over the years, that scientists now call them Newton's Three Laws of Motion.
Newton's Three Laws of Motion:
Newton's Three Laws of Motion:
- Newton's First Law: Every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. Also known as the Law of Inertia. The key point here is that if all the external forces cancel each other out then and there is no net force being applied to it, the object will maintain a constant velocity. The object remains at rest if that velocity is zero. If an external force is applied, the velocity will change because of the force.
- Second Law: The force on an object is equal to its mass times its acceleration. For an object with a constant mass m, the second law states that the force F is the product of an object's mass and its acceleration a: F = m * a
- Third Law: Every action (force) has an equal and opposite reaction. In other words, if object C exerts a force on object A, then object A also exerts an equal force on object C.
