Activity! Try to pull the sheet of paper out from under a stack of Dominoes without having them fall. –How does this activity demonstrate Newton’s First Law of Motion? Answer: The Dominoes are at rest and will remain at rest. The paper was yanked quickly (Motion) and stayed in motion. The Dominoes did not fall because of Inertia and Newton’s First Law of Motion.

Lets hear it. Inertia as it applies to the sport of curling.

Activity! (Optional) Set-up a modified version of curling by taping some colored paper to your floor. –Each table group elects one member to slide their notebook across the floor and try to score for their table. (Friction and Inertia) –Pick an order, and your table group is allowed to knock other notebooks out of the way. –Whatever team is closest to the scoring area at the end wins. Run it again in the opposite direction.

Inertia can pull a car off the road or across the double line and into on coming traffic.

How does inertia apply to this racer?

The driver must have the perfect lean angle of the motorcycle so that the force of gravity reaches equilibrium with the centrifugal force attempting to stand the bike back up.

Center of Mass: Point in a body at which the whole mass may be considered as concentrated.

–Usually associated with center of gravity. Similar concepts on Earth.

Activity: Use the Dominoes to recreate the picture below. –Try and get as far from the table as you can before the center of gravity is off of the edge. –Sketch your stack and draw a line where you think the center of gravity / mass will be.
