1. Inertia By: Anica C, Jack K, Grace S, and Christy T

2. 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.

3. 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)

4. Newton’s First Law • Newton's first law is the law of Inertia. • Newton published his laws in his book Principia.

5. 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.”

6. 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.
