Rocket Midterm

Rockets are able to lift off and travel because of

• thrust
• speed
• velocity
• escape veocity

The amount of thrust (force) produced by the rocket engines needs to be __________ than the force of gravity holding it down.

• Equal
• Greater
• Less

Relating to Newton’s Third Law, action and reaction, what is the reaction when a rocket expels gas, smoke and flames from the nozzle end of the rocket engine?

• Nothing
• Propels in the opposite direction
• Creates a balanced force
• Creates friction

Identify the part of a rocket seen in the picture.

• Nose Cone 
• Fin
• Payload
• Rocket Engine

The part of a rocket engine where hot gasses exit the engine.

• Hydrogen Tank
• Nose Cone
• Oxygen Tank
• Nozzle

As the speed of the rocket increases, the distance

• remains the same.

• increases.

• decreases.

• is balanced.

How do you calculate the average speed of an object?

• You take the mass and divide it by the volume.

• You take the distance the object traveled and divide it by the time the object took to travel that distance.

• You take the mass and multiply it by acceleration.

• You take the distance it traveled and subtract the time.
