Mathematics and Physics megathread

Never even worked for Physics 1, which was the hardest course at the hardest engineering faculty in my uni, and still gave it BA while the average was DC. Tho my math sucks ass tbh.
 
 
Is gravity only between 2 objects?

Does an object emit gravity without the presence of another object to attract it?

If it did not have potential gravity how can it attract another object when it is present in it's vicinity?

Does its gravitational field only arise in the presence of another object?

Or is the other object the cause of the gravity between them?

If gravity acts between all objects in the universe, then why don't all objects clump and condense into an infinite singularity?

"Gravitational potential energy increases as objects are brought farther apart."

That means at infinite distance, gpe is at infinite value.

"objects accelerate towards the Earth, thus losing the gravitational energy transforming it to kinetic energy"

That means at 0 distance between two objects, kinetic energy is infinite.

What is this "transformation" of gpe to ke?

Is it like "as gpe decreases, ke increases"?

Is it "converting"? Why? How is it happening?

Is it, "-1 gpe" = "+1 ke" ?

If gpe converts into ke, causing objects to fall towards the centre of an object.

At what point does it "start falling towards the object"?

This has to be explained.

If I drop something from a mountain it will fall towards the Earth's surface within a certain span of time.

Why then isn't everything in this universe moving towards each other?

If I release a ball 1000km away from another ball in a vacuum space, will it move towards it?

Is it one object moving towards the other or vice versa or both?

What if I increased the mass to infinite?

Things seem to be related within the universe.

Some things seem to be related to others moreso.

Are there completely unrelated things within this universe?

If all physical laws apply all the same throughout the universe, then are all things related?

If laws change does it mean that it's an entirely different universe?

Why do we have the laws that we have?
 
"an object motion will remain in motion unless acted on by a force..." Newton.

Yeah... That's why light just keeps on travelling because it has no mass.

 
I thought light cannot interact with anything.

But it can...

How can something with no mass interact with matter?
 
wtf is this nerd cope nonsense

I dare you to solve this.

All the sides have the same length

Opposite sides are parallel.

Get the area of this hexagon

Different angles of each side of a triangle can be different, they need not be all be the same?

Are triangles either equilateral or isosceles?

Answer me this first and then I'll proceed from there.
 
If I have the length of 2 sides and the degree of the angle between them. Can I deduce the 3rd side?
 
i suck at math

If I turn 27 and lie it flat and make it a straight line with 28, I get 27 + 28 = 52.

52 cm with 180 degrees.

As you increase the length of 28, the angle pivoted at 28 contracts and angle pivoted at 27 increases.
 
nigga watched oppenheimer and suddenly "realized" he had a hidden euler in him :feelskek:

When it forms a triangle you can get the remaining side always.

Two sides with one angle between them SAS

Since the 3 lines are 27, 28 and 29. Clearly it cannot be a Hexagon of sides of equal length.

Try using desmos or online tools if you are suspicious about it actually works with height 27,28 and 29 but hexagon has all equal length

Since it is 27 and 29, the triangle on each side of the hexagon cannot be an isosceles.

The trapezoid is made up of 2 triangles.

The hexagon is made of overlap of three

I don't have an ipad or a ruler or a protractor to work on a paper. I need to use my head.
 
@ngannou are you a Maths major?

Since as you say it's a Hexagon. The inner angles are all 60 since 360 ÷ 6 = 60. The opposite angle is 180 - 60 = 120.

Since all the lines within appear to cut through and meet showing no angles they're all 60 degrees.
 
Since the triangle on each side is an isosceles, the sides towards the bigger angle must be the same.

No it works I will try to draw in desmos if I have time
