The force supplied by the rocket engine must be strong enough to overcome...

• Gravity

• Weight

• Thrust

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

When the rocket engine is falling back down towards earth it is in...

• Air resistance

• Free fall

• Velocity
