Do You Know Anything About Newton’s Laws Of Motion?

Kia ora, in Te Ngahere we have been writing an explanation piece of writing to show what we have learnt in the Wonder Project (I have another post about Wonder Project if you don’t know what it is about). Our writing needed an orientation, three paragraphs and a conclusion. I decided to write each of my paragraphs about how each one of Newton’s laws of motion affects the flight of bottle rockets. I think I did well at explaining how each one of Newton’s laws of motion affects the flight of bottle rockets. Do you know anything about Newton’s laws of motion?

Here is my writing

How The Forces Of Motion Apply To Bottle Rockets.

The forces of motion.

Bottle rockets need three forces of motion to fly. The first law of motion is an object will stay

at rest unless acted on by another force. The second law of motion is the more weight an

object has the more force will be required to move it. The third law of motion is every action

has an equal and opposite reaction. All these laws apply to the flight of bottle rockets.

1. How law one applies to the flight of bottle rockets.

Newton’s first law “An object will stay at rest unless acted on by another force” uses the

thrust/ air pressure to fly. Thrust is what makes your rocket fly through the air without the

thrust the rocket would go nowhere the thrust is the force that acts on the bottle rockets.

You pump the air from the pump to the bottle rocket to create the thrust/ the air pressure.

You then release the air pressure which then creates another force making the rocket fly.

2. How law two applies to the flight of bottle rockets.

Newton’s second law “The more weight you have, the more force you need to move an

object. The more weight you have the more PSI required to move the rocket. The weight

in the rocket is the water and the water shoots out when the air pressure comes out. Say if

there was 10 Psi and 400mls of water the rocket would be too heavy for the pressure to take

effect and the rocket won’t fly. But if there is a good amount of water and Psi, the air

pressure will take effect and start flying.

 

3. How law three applies to the flight of bottle rockets.

Newton’s third law “Every action has an equal and opposite reaction” The rocket uses the

air pressure to fly. Air pressure goes the opposite direction of the rocket to move the rocket

in forward. The water in the rocket also goes the opposite direction to help push the rocket

through the air. The action is the rocket is flying forward and the opposite reaction is the

water and air pressure is going the opposite direction to help the rocket fly forward.

The laws of motion are important in the flight of a bottle rocket. Without knowing how the

laws of motion affect the rocket. It would be harder to get a successful rocket flight.
