In a water rocket, the action force is the water being pushed out of the bottle. What is the reaction force?

• The rocket being pulled by gravity
• The air inside the rocket pushing down
• The ground pushing up on the rocket
• The rocket being pushed upwards

Which of the following best explains why fins are added to a rocket?

• To decrease the rocket's weight
• To increase the rocket's speed
• To improve the rocket's stability
• To enhance the rocket's appearance

According to Bernoulli's Principle, what happens to air pressure as the speed of the air increases?

• Air pressure increases
• Air pressure decreases
• Air pressure remains the same
• Air pressure fluctuates

What is the center of mass in a rocket?

• The point where the rocket’s mass is evenly distributed
• The topmost point of the rocket
• The bottommost point of the rocket
• The point where the rocket's fins are attached

How does the shape of a rocket affect its flight?

• A wide rocket flies faster
• A narrow rocket flies slower
• A streamlined rocket reduces air resistance
• A blunt rocket increases stability

Why is it important to measure the flight duration and distance of a water rocket?

• To determine the rocket's color and shape
• To analyze the rocket's fuel efficiency
• To assess the rocket's design effectiveness
• To compare the rocket's size with others

What role does the nozzle play in the propulsion of a water rocket?

• It releases air slowly
• It controls the direction and speed of water flow

• It wooshes the water out a fast as possible

• It stabilizes the rocket during flight
