Digital News Report – Google honored Sir Isaac Newton today with their apple falling from the tree. Born January 4, 1643, today would have been Newton’s 367th birthday.
Newton was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian who discovered the force of gravity after observing the way apples fell from a tree.
For three centuries, his theories and works held precedence in the scientific community. His discovery of the acceleration of gravity was one of three laws of motion which he is known for.
1) A body in motion or at rest stays in motion or at rest until another force acts upon the object.
2) The acceleration of gravity is dependant on the mass of the body. The force is equal to the time derivative of momentum.
3) When a body exerts a force on another body, the second body also exerts a force on the first. These forces are equal except in opposite directions.
You might remember these laws from your high school physics classes:
First Law: “An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an external force” or “A body persists in a state of uniform motion or of rest unless acted upon by an external force.”
Second Law: “Force equals mass times acceleration” or “F = ma.”
Third Law: “To every action there is an equal and opposite reaction.”
