Co2 Car Concepts

Look at the picture on the bottom right. As the man stretches the slingshot back, he is increasing what type of energy in the elastic band?

• potential

• kinetic

Look at the photo on the top right. The compressed gas in side the soda bottle is under a lot of pressure. There is a lot of potential energy stored in that pressurized gas. When the girl opens the bottle, the gas pushes the soda out. The MOVING soda has what kind of energy?

• potential

• kinetic

To move something from one place to another

• transfer

• transform

To change into a different form

• transfer

• transform

True or False: 

Both water and air are considered fluids.

• True

• False

True or false:

A car slowing down and coming to a stop is technically accelerating.

• True

• False

Your car will be launched from the starting line using compressed air from a CO2 canister, so you can't change the amount of force used to launch your car. Will your car go faster if it has more mass or less mass?

• More mass

• Less mass

Let's say you have a really heavy car with a lot of mass. The mass is 50. What is the rate of acceleration if the force of the push is still 100?

• 2

• 200

Look at the orange arrow in the picture on the bottom right. Is it parallel to the direction the truck is moving or perpendicular to the direction the truck is moving?

• parallel

• perpendicular

Why should you do a LOT of thumbnails?

• It uses up time and makes you look busy.

• When you make thumbnails, you are generating a lot of different ideas quickly and helps you to be more creative.
