What activity did we do in class to demonstrate inertia?
We used a cup, index card, and different objects. We flicked the index card out from underneath different objects and noticed which objects fell into the cup.

Compare and contrast a roller coaster and a carousel (merry-go-round).
The roller coaster is fast; the carousel is slow. The roller coaster has hills and loops; the carousel moves in a circle. Some roller coasters are just for kids and some are just for adults, but anyone can ride the carousel. Both roller coasters and carousels use friction to stop. Both roller coasters and carousels are found at an amusement park.

When you have multiple forces that are pushing against each other, and there is no motion, the forces are ___________________.
balanced

This is when we look at a project after we create it and decide what we could do to make it better.
improve

A change in speed is called _______________.
acceleration

The resistance an object has to a change in motion is called _____________.
inertia

These are 2 things that can keep you safe on a roller coaster. (Think about the roller coaster video we watched).
Lap bar, magnetic locks, brakes, wheels, cars, etc.

When you have multiple forces that are pushing against each other, and they cause motion, the forces are ___________________.
unbalanced

Why is it important to ask, imagine, and plan before we create something?
-Asking a question helps us figure out what the problem is. -Imagining helps us gather all of our ideas about the project. -Planning allows us to put all of our thoughts and ideas down on paper so that we don't forget anything and we think about all important parts of the project.

Newton's first law states that:
An object in motion will remain in motion, and an object at rest will remain at rest, unless acted on by an outside force.

Think about the cup and index card activity. Explain why the wooden block usually fell into the cup and the feather usually fell outside of the cup.
The wooden block has a larger mass so it has more inertia. It has more of a resistance to changing its motion, and it wants to stay in the same place. The feather has a smaller mass so it has less inertia. The feather moves off of the cup with the index card because it has less inertia.

These are two forces that help a roller coaster car move and stop moving.
Gravity helps a roller coaster move. Friction helps a roller coaster stop.

Find two balanced and two unbalanced forces in the classroom.
Balanced: computer sitting on desk, nametag sitting on desk, papers taped to the wall, chairs on the floor, desk on the floor. Unbalanced: people moving, writing with pencil, hand on the clock moving, blowing on nametag/paper.
