Essential Question: <strong>What</strong> <strong>are</strong> <strong>Newton's</strong> <strong>laws</strong> <strong>of</strong> <strong>motion</strong><br />

Sir Isaac Newton<br />

<strong>Newton's</strong> First Law <strong>of</strong> Motion<br />

States that an object in <strong>motion</strong> will remain in <strong>motion</strong> and an object at<br />

rest will stay at rest... unless, some outside force (an unbalanced<br />

force) acts on the object causing it to keep moving or stop.<br />

AKA: The Law <strong>of</strong> Inertia<br />

Inertia is an object's tendency to resist a<br />

change in <strong>motion</strong>.<br />

<strong>What</strong> does that really mean<br />

Think <strong>of</strong> a car crash - the car may stop, but what happens to you ...<br />

You (and everything else in your car) keep moving.<br />
