Sir Isaac Newton and the 3 Laws of Motion
You’ve probably heard about Sir Isaac Newton and the apple that fell on his head.
Sir Isaac Newton, born on January 4th, 1833, was an mathematician, astronomer, and physicist. He was a pioneer in our scientific revolution, laying the foundations of classical mechanics with his book “Mathematical Principles of Natural Philosophy“. And all it began with an apple!
Newton’s First Law of Motion
Newton’s first law of motion was also known as the Law of Inertia. It stated that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
In simpler words, an object that is moving will keep moving until something stops it and and an object that is not moving will not move until something moves it.
Newton’s Second Law of Motion
The second law of motion, also known as the law of force and acceleration, states that that the acceleration of an object is dependent upon the mass of the object and net force acting upon the object.
In simpler words, pushing or pulling an object produces acceleration, a change in the speed of motion.
Remember: Force = Mass x Acceleration
Newton’s Third Law of Motion
The third law of motion states that, for every action, there is an equal and opposite reaction.
