A ball rolling on the ground
A magnet attracting a nail
If the mass of a rocket is 2 kg and the force applied is 10 N, what is its acceleration? (Use F=ma )
2 m/s 2
5 m/s 2
10 m/s 2
20 m/s 2
Which would increase the drag on a rocket?
Making the nose cone sharper
Adding rough surfaces to the fuselage
Reducing the number of fins
Using lighter materials
A rocket travels a distance of 500 meters in 25 seconds. What is its speed?
10 m/s
15 m/s
20 m/s
25 m/s
If you want to reduce friction between two surfaces, what could you do?
Make the surfaces rougher
Add oil or lubricant
Increase the weight on the surfaces
Increase the surface area
A student claims that increasing the mass of a rocket will always make it go faster. Use your knowledge of force, mass, and acceleration to explain if this is correct.
Yes, because more mass means more speed
No, because more mass requires more force to accelerate
Yes, because mass and speed are not related
No, because mass does not affect acceleration
A rocket designer wants to maximize the distance a rocket travels. Which combination of features should they focus on, and why?
Increase drag and weight
Decrease drag and increase lift
Increase friction and mass
Decrease speed and increase time
Explain why the shape of the nose cone affects the rocket’s speed and distance traveled.
It changes the color of the rocket
It affects how much air resistance (drag) the rocket experiences
It increases the rocket’s mass
It changes the type of fuel used
A rocket is not flying straight and keeps spinning out of control. Based on your understanding of fins and aerodynamics, what is the most likely cause?
The rocket has too much fuel
The fins are not properly aligned
The nose cone is too sharp
The fuselage is too long
A student wants to test how different fin shapes affect a rocket’s flight. What is the best way to design this experiment?
Change the fuel type each time
Use the same rocket and only change the fin shapes
Change the nose cone and the fins together
Use different rockets for each test
