What are the applications of Newton's Three Laws of Motion?

In terms of applications for these three laws in every day life, there are few, given that you can operate in your daily life perfectly fine without them. But examples of their use/application in daily life is easier. I can probably describe all three using the car/automobile.1."Force equals mass times acceleration".

The force required to propel your car forwards with you in it is proportional to the mass of the car and its passengers and the amount of acceleration. This means that the heavier it is, and the more people you carry, the more force required. And to generate more force you need more fuel therefore lighter cars use less fuel (if we don't take into account their efficiency of converting the chemical energy of the petrol into kinetic (motion) energy, for which each car is different).

In terms of acceleration it becomes less clear, because it will need less force to accelerate your car if you accelerate less but take longer to reach your top speed. And if you reach your top speed sooner by accelerating more you will generally use the same energy. The things that throw that off are friction of the air, efficiency of your car at different accelerations, and the traction of your tires.

2. "For every action there is an equal and opposite reaction". This one is a little more subtle and you would be forgiven for not realising that it plays any part in driving your car.

Basically whenever you accelerate you are pushing at the ground. This law means that you do not simply move forwards but the ground moves backwards behind you in and equal manner. Of course we know that when we drive off we don't cause the earth to start rotating in the opposite direction as fast as we drive, but then what happens?

Well if we use the first law again we can see why we don't notice a difference. F = m x a, lets say a car is 500kg, and we reach 100km/h in 20 seconds, this is an acceleration of about 1.4 m/s/s.So the force we exert on the earth is 700N(newtons). Now thats the force we apply to the earth, so to find out its acceleration we rearrange the formula to a = F/m.

Now the mass of the earth is 5 973 360 000 000 000 000 000 000 kg. Using the force of 700N we end up with an acceleration of 0.000 000 000 000 000 000 000 117 187 m/s/s. This shows us that the effect on the earth of our acceleration is tiny, and therefore we don't have to worry about it.

Also because we are a part of the earth our motion is cancelled out when we brake, change direction, etc, resulting in a net effect to the earth of zero. Only objects leaving the earth would make permanent changes. 3.

"An object that is at rest stays at rest unless a force is exerted upon it". This one generally makes sense if you don't look too deeply into the meaning of the term "at rest". A car that is still is not going to accelerate unless a force is exerted upon it.

Be that the force of the engine or gravity down a hill. Where it becomes more interesting is when we realise that something "at rest" can be in motion too. When you are travelling down the road at a constant speed you are technically "at rest" and your motion won't change unless forces are exerted upon you.

Unfortunately there are plenty of other forces resisting your motion so constant force is required to maintain your speed. These forces are mostly friction from the air, the road and the connections inside your car which join your wheels to the engine. If you could drive in a frictionless environment you wouldn't use any fuel after you had reached the speed limit except for any speed lost from turning.

How this is applied to car design is that cars are often designed more and more aerodynamic, reducing the amount of air friction drag on the car, allowing them to cut through the air with less resistance. This means that you can coast using less fuel, which is ideal for open road driving. I hope that helped, and made sense, just ask any questions if you need to.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
