1, Newton's first law of motion:
Newton's first law of motion, referred to as Newton's first law. Also known as the law of inertia. A common and complete statement: any object must keep moving in a straight line or at rest at a constant speed until an external force forces it to change its state of motion.
2, Newton's second law of motion:
The common expression of Newton's second law of motion is that the acceleration of an object is directly proportional to the acting force, inversely proportional to the mass of the object, and directly proportional to the reciprocal of the mass of the object; The direction of acceleration is the same as that of acting force.
This law was put forward by isaac newton in his book Mathematical Principles of Natural Philosophy 1687. Newton's second law of motion, the first and third laws together constitute Newton's law of motion, and the basic law of motion in classical mechanics is expounded.
3, Newton's third law of motion:
The common expression of Newton's third law of motion is that the acting force and reaction force between two interacting objects are always equal in size and opposite in direction, and act on the same straight line.
This law was put forward by isaac newton in his book Mathematical Principles of Natural Philosophy 1687. Newton's third law of motion, the first and second laws together constitute Newton's law of motion, and the basic law of motion in classical mechanics is expounded.
