Rockets Quiz

Rockets are able to lift off and travel because of

• thrust

• speed

• velocity

• escape velocity

The amount of thrust (force) produced by the rocket engines needs to be: (select one of the following choices below), than the force of gravity holding it down.

• Equal

• Greater

• Less

• It makes no difference

Identify the part of a rocket seen in the picture.

• Nose Cone

• Fin

• Payload

• Rocket Engine

All the forces that act on moving rocket are

• Lift, Weight, Gravity & Thrust

• Lift, Drag, Gravity & Thrust

• Lift, Push, Pull & Drag

• Lift, Thrust & Drag

Resistance that slows an object down in the atmosphere (air).

• Drag

• Fin

• Fuselage

• Speed of Sound

Two identical soccer balls are launched across the field by a catapult five minutes apart. One soccer ball travels 5 meters further than the other. What explanation can be given for this difference?

• One ball experienced more gravity than the other.

• One ball experienced more drag because of the wind.

• One ball was heavier than the other.

• It is impossible for the two balls to travel different distances.

Rockets use the following energy to combat the oppositional forces to get into space

• chemical

• electrical

• gravitational

• magnetism

Newton’s first law can be applied to rockets because

• The rocket can be pulled by gravity

• It needs thrust to overcome oppositional forces

• It has static electricity

• There is no air in space

The weight of a rocket

• Measured in joules.

• More when there are strong headwinds.

• Is the amount of gravitational force on the rocket.

• Is the same as the mass of the rocket.

• Nose Cone

• Fins

• Pressure Vessel

• Paint
