What force pushes the CO₂ dragster forward?
What force slows the car down when it moves?
What happens when air pushes against the dragster while it moves?
The car slows down because of drag
What is the name of the force that pulls the car down toward the track?
Which car shape will be the fastest?
What happens when the CO₂ gas is released from the cartridge?
The car turns sideways
The car stops moving
The car moves backward
The car moves forward quickly
What type of energy is stored in the CO₂ cartridge before the race?
What happens to the potential energy in the CO₂ cartridge when the car starts moving?
The potential energy is converted into kinetic energy.
What is the term for an object's ability to keep moving after it starts?
Which of the following will help make a CO₂ dragster go faster?
(a) that makes the CO₂ dragster move (b) is (c) . It comes from the (d) pushing out of the cartridge, following Newton’s (e) (action-reaction).
The force that makes the CO₂ dragster move forward is (a) (thru...). It comes from the CO₂ gas pushing out of the cartridge, following Newton’s Third Law of Motion (action-reaction).
The force that makes the CO₂ dragster move forward is thrust. It comes from the CO₂ gas pushing out of the cartridge, following Newton’s (a) (Tri... La... of Mo....) (action-reaction).
(a) is (b) that (c) car by (d) between the wheels and the track. If the wheels are rough or uneven, friction increases, and the (e)
(a) is (b) that pushes (c) as it moves forward. More drag (d) car down, so a (e) helps the car move faster by reducing drag.
Drag is air (a) (resist...) that pushes against the car as it moves forward.
More drag slows the car down, so a (a) (stream...) shape helps the car move faster by reducing drag.
When the race starts, the CO₂ gas is (a) from the (b) This creates a strong (c) (thrust) that (d) the car forward.
When the race starts, the CO₂ gas is (a) (relea...) quickly from the cartridge.
When the race starts, the CO₂ gas is released quickly from the (a) (cartr....).
A (a) car moves (b) because it requires less force to push forward. A (c) car has more (d) and gravity pulling it down, which can slow it down.
A (a) (light...) car moves faster because it requires less force to push forward.
A heavier car has more (a) (frict...) and gravity pulling it down, which can slow it down.
A heavier car has more friction and (a) (gravi...) pulling it down, which can slow it down.
(a) energy is (b) in the CO₂ (c) before the gas is released. Once the gas (d) , the energy changes into (e) energy, making the car move.
(a) (poten.... ener...) is stored energy in the CO₂ cartridge before the gas is released.
Once the gas is released, the energy changes into (a) (kine.. ene...), making the car move.
(a) energy is the energy (b) . The dragster has (c) after the CO₂ is released and the car starts (d)
The dragster has kinetic energy after the CO₂ is (a) (relea...) and the car starts moving forward.
The car (a) because of (b) (between the wheels and track) and (c) (air resistance).
When the CO₂ (a) , there is no more (b) to keep the (c) fast.
(a) is the (b) that keeps the car (c) after it (d)
A (a) car has more (b) , so it can travel (c) before (d)
A faster car has more (a) (momen...), so it can travel farther before stopping.
What are three ways to make a CO₂ dragster faster?
1. (a) → Use a smooth, aerodynamic shape
2. (b) → Use smooth wheels and axles.
3. (c) → Make sure the car is not too heavy but also not too light.
What force makes the CO₂ dragster move forward?
How does friction affect the speed of the dragster?
What is drag, and how does it affect the race?
How does weight affect the speed of the dragster?
What are three ways to make a CO₂ dragster faster?
