Stage 4 Technology TE4-8EN-Force, Energy and Motion

What force pushes the CO₂ dragster forward?

• Magnetic force from the track.
• Gravity pulling the dragster downwards.
• Thrust from the escaping CO₂ gas.
• Friction from the wheels on the ground.

What force slows the car down when it moves?

• Road incline and surface type
• Engine power and torque
• Gravity and inertia
• Friction and air resistance

What happens when air pushes against the dragster while it moves?

• Air creates a vacuum that pulls the dragster forward.
• The dragster becomes lighter due to air pressure.
• Air helps the dragster accelerate faster.
• The car slows down because of drag

What is the name of the force that pulls the car down toward the track?

• Magnetism
• Gravity
• Inertia
• Friction

Which car shape will be the fastest?

• Boxy shape
• Compact shape
• SUV shape
• Aerodynamic shape

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?

• Electrical energy from batteries
• Kinetic energy from movement
• Potential energy in the form of compressed gas
• Thermal energy from heat

What happens to the potential energy in the CO₂ cartridge when the car starts moving?

• The potential energy increases as it is stored in the cartridge.
• The potential energy remains unchanged while the car is moving.
• The potential energy is released as heat instead of kinetic energy.
• The potential energy is converted into kinetic energy.

What is the term for an object's ability to keep moving after it starts?

• Momentum
• Velocity
• Inertia
• Acceleration

Which of the following will help make a CO₂ dragster go faster?

• Add more CO₂ canisters for power
• Reduce friction and optimize aerodynamics.
• Use larger wheels for more drag
• Increase weight for stability
