Water Bottle Rocket Review

Center of gravity determines the _________ of a rocket

• rockets mass

• point of drag

• rotation point

• arrow dynamics

The fins of a rocket help it to fly straight rather that flip over end. This is because the fins .....

• decrease the friction

• increase the inertia

• Increase the drag

• decrease the mass

Inertia is related to Newton's

• 1st law of motion

• 2nd law of motion

• 3rd law of motion

What does Specific Impulse measure?

• The height of a rocket

• The efficiency of the engine thrust

• The mass of the rocket

• The velocity of the rocket

The rocket will _______________in speed until all of the fuel is gone.

• Increase

• Decrease

• Increase and then Decrease

• Remain constant

Momentum can be calculated by

• Mass x Velocity

• Mass x Density

• Density x Velocity

• Velocity Squared

Parachutes help slow down the rocket by increasing ______

• Volume

• Speed

• Arrow dynamics

• Drag

Center of mass and Center of drag help the rocket

• accelerate

• slow down

• fly straight

• stop rotation

Pressure can be calculated by

• mass x acceleration

• force x acceleration

• force x density

• velocity x mass
