How exactly are the four laws of physics different and how is gravity even a ‘force’?

Inqusitive: How exactly are the four laws of physics different and how is gravity even a ‘force’?
I read an intro on the four laws of physics and to me they seem like the same law of gravity/attraction… just on different size scales. For example; in electromagnetism, Isn’t ‘magnetism’ a form of gravity since it is basically attraction between objects? Also, how is gravity even a ‘force’.

I only feel qualified to talk about the first two forces, Gravitational and and Electromagnetic force.
Gravitational force is the force we feel most comfortable with on our macro size scale. This is the force that is exerted on, lets say, an apple as it falls out of a tree, or even the moon as it orbits earth. Gravity causes objects — any object with mass — to be attracted or accelerate towards other objects with mass. In reference to your thought on how gravity can be a force, I would probably consider ‘gravity’ a force field (9.8 m/s^2 on the surface of earth). Gravitational force is a more generic relation given by F = GM1*M2/D^2
Electromagnetic force is mathematically described similarly to gravitational force, but it is the force that will stick a balloon to the wall if you charge it up. In order to have electromagnetic force, two objects must have net charges (like too many electrons or protons). We have a hard time understanding how electronic forces are important, but on the atomic level, solids and liquids are held together due to electronic forces.
Magnetic Forces are more complicated. They are due to a moving charge. This can either be in the electrons ‘orbiting’ an atom, as is found in permanent magnets, or in a wire, as would be found in a speaker or in a motor.

I am half way done a materials science degree, but I know little or nothing about the nuclear forces. Sorry.

I know this answer is far from complete but I hope it helps.

Answer by Kamyar G
electromagnetism can attract and repel objects due to the charge of the objects.
strong force it the force that holds the neutrons and protons together and is way stronger than gravity.
i don’t know much about week force but its what makes neutrons unstable.
and gravity is the attraction between any two objects and is way Wekker than other forces (even week force).
and gravity is a force because it can make things move.

Answer by poncadave
I think you mean the 4 forces.
Gravity is the one that string theory is trying to unite.
To move an object you need a force.
If gravity isn’t a force then rocks should float..they don’t.
What pulls them to the ground?
Gravity works on every mass. Very different from a magnet which is electrical potential differance as is electromagnatism.
Gravity is done by the warping of space.
A thin slice of space is like a blanket suspended in air.
drop a bowling ball in the middle and then a baseball next to it
they both warp the plane of the blanket. but the baseball will move to the bowling ball.
Without an electrical potential difference.it still works
and since an object moves a force must cause it.
String theory trys to unify all of the KNOWN forces.
Google that for more info.
But Gravity is indeed a force by all of our known definitions.

I think it’s all to do with charge.
