What is newton law
Newton's laws of motion are three fundamental principles that describe the relationships between the motion of an object and the forces acting on it. They were formulated by Sir Isaac Newton in the late 17th century and are widely regarded as the foundation of classical mechanics.
Here are the three laws of motion:
1. Newton's First Law of Motion (Law of Inertia):
- "An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
- This law basically states that objects will remain in their state of motion (either at rest or moving with constant velocity) unless an external force is applied to change that state.
2. Newton's Second Law of Motion (Law of Acceleration):
- "The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass."
- This law mathematically relates force, mass, and acceleration. It states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass.
3. Newton's Third Law of Motion (Law of Action and Reaction):
- "For every action, there is an equal and opposite reaction."
- This law states that if an object A exerts a force on object B, then object B exerts an equal and opposite force on object A. Forces always exist in pairs.
To understand and apply Newton's laws of motion, you will need to have a basic understanding of concepts like forces, acceleration, velocity, and mass. By analyzing the forces acting on an object and applying these laws, you can determine and predict its motion.
