Newton’s Laws of Motion
Sir Isaac Newton (1642 – 1727) was a brilliant mathematician, astronomer and physicist who is considered to be one of the most influential figures in human history. Newton studied a wide variety of phenomena during his lifetime, one of which included the motion of objects and systems. Based on his observations he formulated Three Laws of Motion which were presented in his masterwork Philosophiæ Naturalis Principia Mathematica in 1686.
Newton’s First Law – An object at rest will remain at rest and an object in motion will remain in motion at a constant speed unless acted on by an unbalanced force (such as friction or gravity). This is also known as the law of inertia.
Newton’s Second Law – An object’s acceleration is directly proportional to the net force acting on it and inversely proportional to its mass. The direction of the acceleration is in the direction of the applied net force. Newton’s Second Law can be expressed as: F = ma
Newton’s Third Law – For every action there is an equal and opposite reaction.

Newton's first law is often called the law of inertia. How can we use Newton's 1st law of motion to make improvements to our car in the future? Upload a picture of your car to help you explain.

Newton's second law describes the relationship between force, mass, and acceleration. How might you make improvements to your car using Newton's second law? Upload a picture of your car to help you explain.

Think about Newton's third law of motion: For every action, there is an equal and opposite reaction. How might you apply this concept to help you to improve the performance of your car? Upload a picture of your car to help you explain.
