**Inertia**By: Anica C, Jack K, Grace S, and Christy T**What is inertia?**• Inertia is the tendency of an object to resist being moved or, if the object is moving, to resist a change in direction until an outside force acts on the object. • For example, car collision is a force acting on a moving object causing it to stop abruptly.**What is the measure of Inertia?**• Mass is the measure of Inertia. • A bowling ball has a great amount of mass which means it has a great amount of Inertia because it resisting of being moved. (kicking)**Newton’s First Law**• Newton's first law is the law of Inertia. • Newton published his laws in his book Principia.**More fun facts about inertia**• Another effect of inertia is if an object is stationary if an outside force acts on it’s speed and direction will change. • According to, http://www.houseandhome.org/facts-on-inertia “Everything that moves has momentum, which means that it will not slow down or speed up or change direction unless forced to.” • According to, http://www.houseandhome.org/facts-on-inertia “Everything that is standing still has inertia, which means that it will not move unless forced to.”**What is momentum?**• Momentum- force or speed of movement • If a wagon full of kids and a wagon that is empty goes down a hill, the wagon with the larger mass (the wagon with the kids) will go down faster than the empty wagon.**Resources**• www.houseandhome.org/facts-on-inertia • en.wikipedia.org/wiki/Inertia • dictionary.reference.com • Clip art • http://www.physicsclassroom.com/class/newtlaws/u2l1b.cfm
