Rockets Pre-Assessment

What two forces slow a rocket down as it is being launched?

• Thrust & Lift

• Weight & Drag

The nose cone of the rocket is shaped to...

• Increase thrust

• Decrease drag

• Increase drag

How does Newton's third law explain how a rocket will take off?

• The rocket doesn't move until ignition

• The more mass the rocket has the more force is needs to take off

• Gas pushes down, the rocket goes up.

The force used to provide lift for the rocket is...

• Weight

• Control

• Thrust

• Inertia

Explain how Newton's second law affects a rocket:

• A rocket stays at rest until ignition

• Gas pushes down, the rocket goes up

• The more mass the rocket has the more force it needs to take off

When a rocket is sitting on a launch pad, what type of energy does it have?

• Potential

• Kinetic

• Gravity

When a rocket is blasting off into space, what type of energy does it have?

• Potential

• Kinetic

• Gravity

Why is it important to have fins on your rocket?

• They stabilize the rocket

• The reduce drag

• They evenly distributes the weight

Which of the four forces on a rocket is affected by gravity?

• Weight

• Thrust

• Lift

• Drag

What is the principle of inertia?

• All matter, because of its mass, resists changes in motion.
• Some matter, because of its mass, resists changes in motion.
• All matter, because of its weight, resists changes in motion.
• Some matter, because of its mass, resists changes in motion.
