Isaac Newton laid the blueprints for his three laws of motion, still recited by physics students, in 1666. Credit: Library of Congress Isaac Netwon is synonymous with apples and gravity.
Isaac Newton (a 17th century scientist) put forth a variety of laws that explain why objects move (or don't move) as they do. These three laws have become known as Newton's three laws of motion. The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as 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.
