What are the 3 laws of physics?

Answer 1

If you're referring to Newton's Laws, the are

1) an object at rest will remain at rest until acted on by a force.

This is saying that if a soccer ball is sitting on the ground, it will stay there until someone kicks it, or moves it in some other way. Pretty much common sense.

2) Force = mass x acceleration

This is an equation- it says that force is directly proportional to acceleration and mass.

3) For every action, there is an equal and opposite reaction.

This is saying that forces come in pairs. If I were to bang my head on the wall right now, it would hurt since the wall appiles a force back to my head equal to the force I applied while headbashing it.

I hope this helps.

Answer 2

The contradiction was not resolved until 1905. That year, Albert Einstein analyzed the measuring process itself and, as a result, proposed his special theory of relativity. The theory begins with two postulates (fundamental principles). The first postulate states that for all observers moving uniformly relative to each other, the laws of physics have the same form. The second postulate states that for all observers, the speed of light is invariant (has the same value). One conclusion from these postulates is that mass and energy are related. Einstein expressed this relationship in his famous equation E equals m times c-squared. In this equation, E stands for energy, m for mass, and c-squared for the speed of light multiplied by itself.

Answer 3

The three fundamental laws of physics refers to newtonian laws of classical mechanics.
1.Every body tends to be in its state of rest or of uniform motion unless it is compelled to change its state of motion by the action of an external force.
2.F=ma.The external force is directly proportional to the acceleration of the body.
3.To every action there is an equal and opposite reaction.

Answer 4

There are many laws to do with physics, several containing 3, but the most obvious is Newton's 3 laws in regards to motion.

1) Thing won't move unless you push it.
2) Thing moves if you push it.
3) If you push thing, it pushes back.

I dare you to quote me.

Answer 5

Physics in overall, looking through all the sight blinding, mind breaking formulas, is juz 1 law. Energy cannot be created nor destroyed. It must to convert from 1 form to another.

Answer 6

There a much more laws of physics. Among them:
4 laws of Newton
4 laws of Maxwell
3 laws of thermodynamics
At least 4 conservation laws (mass and energy, charge, impulse and impulse momentum)
Laws of Pascal, Bernoulli, Archimedes, Ohm and many more.
Th

Answer 7

1) An object will maintain its state of motion unless an external force acts upon it.
2) Net Force = Mass Acceleration
3) For every action, there's an equal and opposite reaction.

Answer 8

zeroth law :
If 2 people copy an idea from a third, then they will all tend to think the same way.

first law :
In any world, the total intelligence remains constant (if you get more people, they get dumber proportionaly to the increase in population)

second law :
Even without an increase in population, the people will tend to get dumber anyway

third law :
If a population is dumb, it will stay that way, and you can't do anything about it.

(for those who didn't understand, this is a joke)

Answer 9

Conservation
Entropy
The Big Chill


or for "gravity=intelligent falling" crowd:

Unity
Disarray
Absolution


actually they should remember the zeroth law of thermodynamics. that if 2 systems are in thermal equilibrium to a third they are in equilibrium with each other. all things being equal we would have less religious bickering.

Answer 10

an object in motion stays in motion unless acted upon by an outside force.

the net force acting upon an object causes acceleration, with the magnitude of the acceleration directly proportional to the net force and inversely proportional to the mass.

to every action there's an equal and opposite reaction

(but don't quote me)
