Space rockets

The video explains how rockets launch into space using Newton's Third Law of motion. It describes the mechanics of rocket propulsion, where the engine burns fuel to produce gas that exits the exhaust nozzle, pushing the rocket upwards. This process relies on the principle that every action has an equal and opposite reaction, as discovered by Sir Isaac Newton. The video concludes by highlighting the continuous force exerted by the engine, allowing the rocket to ascend through the atmosphere into space.

What is the main challenge a rocket faces when trying to launch into space?

• Finding a surface to push against

• Overcoming air resistance

• Maintaining fuel efficiency

• Dealing with gravity

Who is credited with formulating the law that explains the action-reaction principle?

• Nikola Tesla

• Sir Isaac Newton

• Galileo Galilei

• Albert Einstein

According to Newton's Third Law, what happens when an object exerts a force in one direction?

• It experiences a force in the same direction

• It stops moving

• It experiences an equal force in the opposite direction

• It moves faster

What role does the gas play in the propulsion of a rocket?

• It reduces the weight of the rocket

• It creates a vacuum for the rocket

• It pushes the rocket upwards by being expelled downwards

• It cools the rocket engine

How does a rocket continue to ascend into space?

• By using solar energy

• By continuously expelling gas

• By increasing its weight

• By reducing its speed
