# Fun Exercises for Newton's Laws of Motion

Sir Isaac Newton, born on January 4, 1643, was a scientist, mathematician, and astronomer. Newton is regarded as one of the greatest scientists who ever lived. Isaac Newton defined the laws of gravity, introduced an entirely new branch of mathematics (calculus), and developed Newton's laws of motion.

The three laws of motion were first put together in a book published by Isaac Newton in 1687, Philosophiae Naturalis Principia Mathematica (Mathematical Principals of Natural Philosophy). Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. They have been expressed in several different ways, over nearly three centuries, and can be summarized as follows.

## Newton's Three Laws of Motion

1. Every body continues in its state of rest, or of uniform motion in a straight line unless it is compelled to change that state by forces impressed upon it.
2. The acceleration produced by a particular force acting on a body is directly proportional to the magnitude of the force and inversely proportional to the mass of the body.
3. To every action there is always opposed an equal reaction; or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.

If you are a parent or teacher who wants to introduce your students to Sir Isaac Newton, the following printable worksheets can make a great addition to your study. You might also want to look at resources such as the following books:

• Isaac Newton and the Laws of Motion - This book is written in graphic-novel format, making it much more appealing to students than a standard textbook. It tells the story of how Isaac Newton developed the laws of motion and the law of universal gravitation.
• Force and Motion: An Illustrated Guide to Newton's Laws - Author Jason Zimba breaks with the traditional method of teaching the laws of motion by explaining them visually. The book is organized into seventeen brief, well-sequenced lessons that are each followed with problems for students to work.
