Example of the second law of motion is: An aircraft’s motion resulting from the aerodynamic force, aircraft thrust and weight. Momentum is described as the mass m of an object times its velocity V. This law defines a force to be equal to a change in momentum (mass times velocity) per change in time. Newton’s Second Law states that ‘The acceleration of an object depends on the mass of the object and the amount of force applied’. An example of the First law of motion is : The motion of a round ball falling down through the atmosphere, A rocket being launched up into the atmosphere. If any external force acts on an object, the velocity will change because of the force applied. If the Velocity remains at zero, then the object remains at rest. If this happens, then the object will maintain a constant velocity. There will be a net force on an object if all the external forces cancel each other out. The tendency of an object to resist changes in a state of motion is inertia.
This law describes that every object will remain at rest or in uniform motion in a straight line unless forced to change its state by the action of an external force. Newton’s First Law states that ‘An object at rest remains at rest, and an object in motion remains in motion at a constant speed and in a straight line unless acted on by an unbalanced force’. Sir Newton’s three laws are Newton’s First Law: Inertia, Newton’s Second Law: Force, Newton’s Third Law: Action & Reaction. Newton’s three laws of motion help someone understand how objects behave when standing still, when moving and when forces act upon them. Although Newton’s laws of motion may seem so general today, they were considered revolutionary centuries ago.
Newton’s three laws together with Kepler’s Laws explained the concept of planets moving in elliptical orbits rather than in circles. After the development of the three laws of motion, Newton revolutionized science. By understanding the concept, it provides all the information about the basis of modern physics. Newton’s laws of motion explain the connection between a physical object and the forces acting upon it. Isaac Newton discovered the Laws of Motion.
