# What are newton's three laws of motion?

According to the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass multiplied by its acceleration. In the third law, when two objects interact, forces of equal magnitude and opposite direction are applied to each other 3 days ago. To understand Newton's third law with the help of an example, let's consider a book resting on a table.

Newton's second law of motion describes what happens to the massive body when an external force acts on it. Sir Isaac Newton's laws of motion explain the relationship between a physical object and the forces acting on it. Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless it is forced to change its state by the action of an external force. Newton's second law states that the acceleration of an object produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force and inversely proportional to the mass of the object.

Newton's third law of motion describes what happens to the body when it exerts a force on another body. Otherwise, there would be a net force other than zero at a massless point that, according to the second law, would accelerate the contact point by an infinite amount. Newton's first law of motion implies that things cannot start, stop, or change direction on their own, and some outside force is required to bring about that change. The second law of motion states that the force acting on the body is equal to the product of its mass and acceleration.

According to Newton's first law of motion, plates and glasses remain in their state of motion (rest); as a result, they remain unchanged. The three laws of motion help us to understand how objects behave when they are still, when they move and when forces act on them. In 1686, he presented his three laws of motion in the “Principia Mathematica Philosophiae Naturalis”. Below is a short film with Orville and Wilbur Wright and a discussion of how Newton's laws of motion were applied to the flight of their airplanes.
