I just figured out how momentum works!

[Key of door]

When I was 5 I was wondering why if I jump in a plane I don\'t fly to the back and die.

Now about 56320.34 years later I finally figured out what momentum is.

It is an invisible hand that holds on to me when I jump, in everything that moves this hand is on me.

Now you try to explain other forces like Inertia and Gravity

Nobody really knows exactly what gravity is, so I\'ll save you the trouble

Gravity is other hands trying to pull me down

Inertia is when another hand is holding an object when I try to use boosters to launch it.

So the universe is just a whole bunch of hands pulling on me?

Inertia makes things lazy. An object at rest wants to stay at rest. An object in motion wants to stay in motion. A ball resting on the ground will not move unless prompted, say, by you kicking it - it\'s inertia means it\'s happy to sit there. If you throw a ball on earth it has external forces acting on it, most notably drag for this example. This slows it down. If you throw the same ball in space.. it\'ll just fly off into the ether. With no external force to slow it down it\'s inertia keeps it moving forever.

In your aeroplane example, the aircraft has used it\'s engines to overcome your inertia and given you momentum. Unless there is a force acting on your body counter to that while you\'re in that sealed tube, your momentum will continue.

I hope you can also understand by this point the relationship between mass and inertia. Lifting SpaceLab is more difficult than lifting John Glenn. Not just because it weighs more, but because it\'s massive inertia makes it more difficult to move.

I did not mean literal definitions of the forces.

Well I\'m hardly going to use your hand metaphor...

Could get sexy ugly.

[your mom]

why do you have to think like that.

This thread is like watching a bunch of economists trying to explain physics in terms they can understand.

Perhaps that\'s a bad example :u

How moar boosters work,

The hands the FUCKING FLING THAT ROCKET RIGHT INTO SPACE

The fire that comes out the bottom is an illusion , it is really light trying to catch up, time is slowed down to make it look slower.
