- Trophosphere
- gravity
- this is a rocket as you can see it has a desighn that lets it cut into the air easier reducing drag.
- the fuel is stored in here where its later ignited and produces the thrust for the rocket. there is a spiral desighn in the cylinders that keep the rocket stable when the air is coming out of it
- that is gravity acting on the rocket even before it takes off
- fun factdid you know most rockets are launched at the equator because it moves faster in earths rotation basically using the earth as a giant slingshot to fling the rocket further.
- troposphere
- gravity
-
- gravity is still acting on it even before it takes off
- takes a bit of time for the thrust to become greater than gravity causing the rocket to fly up
- net force
- mesosphere
- the higher you go up in earths atmosphere both the preassure and affect of gravity becomes weaker causing there to be less friction and weight force increasing the net force of the rocket
-
-
-
- net force
- due to the air being hotter in the thermosphere causing the air to be less dense causing less friction.
- thermosphere
- net force
-
-
-
- this is the thrust since its greater than gravity and the drag the rocket is going up.
- those 2 vectors are the drag and gravity. drag is air resistance so its trying to slow the rocket down while gravity is trying to pull the rocket to the ground.
- net force
- in space
-
- the thrust keeps propelling the rocket even after leaving earths atmosphere and with no more fuel to burn this is because of newtons third law where when a object is in motion it will stay in motion until a external force acts on it due to their being no external forces in space at the moment the rocket can keep going with out any extra fuel.
- net force
- in space
-
- now in space rockets can't completely stop like a car but can decelerate themselves right before they get to there destination so they don't have a crash landing.
