Lesson 1: Newton`s First Law of Motion
... Inertia is the resistance an object has to a change in its state of motion. Galileo, the premier scientist of the seventeenth century, developed the concept of inertia. Galileo reasoned that moving objects eventually stop because of a force called friction. Isaac Newton built on Galileo's thoughts a ...
