Model Rockets

Igniter

12

For every action there is an equal and opposite reaction

Forces always come in pairs! Action and Reaction

Examples:

•A rife and its recoil

•Driving a Car

•Air let out of a balloon

Law of Action and Reaction

13

• It’s kind of like the balloon

• Burning the fuel creates gas

• The rocket pushes on the gas (action)

• The gas pushes back on the rocket and propels it forward

How do Rockets Engines Work?

14

• Gravity

• Orbital Velocity

• Satellite is in free fall

• Perfect balance
