CO2 Dragster Physics Concepts Worksheet

Newton's Laws of Motion - First Law (Inertia): What does the first law of motion state?

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

• For every action, there is an equal and opposite reaction.

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• Energy cannot be created or destroyed, only transformed.

Newton's Laws of Motion - First Law (Inertia): How does this law apply to a CO2 dragster?

• A CO2 dragster remains at rest until acted upon by an external force.

• A CO2 dragster accelerates indefinitely without any force.

• A CO2 dragster changes direction without any force.

• A CO2 dragster stops immediately when the force is removed.

Newton's Laws of Motion - Second Law (F=ma): What is the formula for the second law of motion?

• F = ma

• F = m/a

• F = a/m

• F = m + a

Explain how the mass of the dragster affects its acceleration.

• The greater the mass, the greater the acceleration.

• The greater the mass, the lesser the acceleration.

• The mass does not affect the acceleration.

• The mass affects only the speed, not the acceleration.

Newton's Laws of Motion - Third Law (Action and Reaction): Which of the following best describes the third law of motion?

• For every action, there is an equal and opposite reaction.

• An object at rest stays at rest unless acted upon by an external force.

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• Energy cannot be created or destroyed, only transformed.

Newton's Laws of Motion - Third Law (Action and Reaction): How does the CO2 cartridge demonstrate this law in action?

• The CO2 cartridge releases gas, pushing the object forward while the gas is pushed backward.

• The CO2 cartridge absorbs energy, causing the object to move backward.

• The CO2 cartridge remains stationary, demonstrating no action or reaction.

• The CO2 cartridge pulls the object towards it, demonstrating attraction.

Aerodynamics - Air Resistance (Drag): Air resistance is a type of?

• Friction

• Gravity

• Magnetism

• Electricity

Aerodynamics - Air Resistance (Drag): Designing a dragster to minimize air resistance involves:

• Increasing the surface area

• Using a streamlined shape

• Adding more weight

• Using rough surfaces

Friction - Rolling Friction: What is rolling friction?

• A type of friction that occurs when an object rolls over a surface.

• A type of friction that occurs when an object slides over a surface.

• A type of friction that occurs in fluids.

• A type of friction that occurs in a vacuum.

Friction - Rolling Friction: How can you reduce rolling friction in your dragster's design?

• By increasing the weight of the dragster

• By using smoother wheels

• By adding more surface area to the wheels

• By using rougher wheel surfaces
