Answer to Question #188654 in Mechanics | Relativity for Melissa

Question

Demonstrate your understanding of the following through reference to the relevant authors and the findings from their research.

• Newton’s Laws of Motion.

• Ideal gas laws.

• You must apply both of these to a range of physical situations by giving appropriate examples.

Answer 1

Answers:-

1.)

Newton’s laws of motion

First law -, if a body is in rest or moving at a constant speed in a straight line than, it will remain at rest or may keep moving in a straight line at constant velocity unless or untill it is acted upon by a external force.

eg. A person sitting in bus

 F = ma

eg. simple example is , we pull or push lighter things easily compared to heavier things.

Third law - to an action there is equal and opposite reaction.

eg. the recoil force by gun is example of third law.

2.) Ideal gas laws

(basic law is pv = nRT , p=pressure , v=volume , n =amount of substanc , R e=ideal gas constant , T=temperature)

Boyle’s Law it is

$P \propto \dfrac{1}{V}$

eg.

$P_1V_1=P_2V_2$

Charles's Law 

$V\propto \; T$

eg.

$\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

Avogadro's Law

$V \propto \; n$

eg.

$\dfrac{V_1}{n_1}=\dfrac{V_2}{n_2}$

Amontons's Law

$P \propto \; T$

eg.

$\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$
