Examples of Newton's Three Laws of Motion
Sir Isaac Newton, the English physicist and mathematician whose name is still revered to and quoted by many around the world, is well known for his contributions in these two fields.
He is known for making many ground breaking theories such as Infinitesimal Calculus, Universal gravitation, Newtonian mechanics and Optics Binomial series.
But out of all these he is known for his three laws of motion.
So let us understand this concept with a few examples of Newton’s three laws of motion.
The first law is also known as law of inertia and it says that a body will tend to be in rest or in motion unless it is subjected to an external force.
The following example is the first part of all the examples of Newton’s three laws of motion.
Consider the following scenario. If you keep a glass full of water on a table in your home where there is no air flowing what will happen to the water level? It will remain the same right? Yes that is because there is no external force acting upon it.
But if we were to insert our finger in the glass or turn on a table fan nearby then the water in the glass will start shaking and will spill out of the glass.
This is because the water which was in a state of rest wants to continue to be in the state of rest and therefore it will push the excess water outside so that it can return to its original state of rest.
The second law of motion states that acceleration is produced when a force acts on a mass. The more the mass the greater the force required to push it. The second law of motion gives us the famous expression F = ma (where F is force, m is mass and a is acceleration).
Let us now see the second part to the examples of Newton’s three laws of motion. Why do you think it’s easier to push away a slim person than a fat person? In same breath, why do you think it is easier to kick a football than a bowling ball?
The answer lies with Newton’s second law of motion. It’s because a fat person has more mass and hence to make him move one has to exert a greater force.
Similarly the mass of a bowling ball is much more than the mass of a football so to make it move a greater force is required.
The third law of motion which many of us would have heard of is for every action there is an equally opposite reaction.
The following examples are for the third and final part of the examples of Newton’s three laws of motion.
When a fireman opens the nozzle of the water pipe connected to the fire preventive unit, he usually goes a few steps backward.
This is because the water that is forced out the water nozzle exerts an equally opposite force to the water hose due to which the fire personnel is pushed backward.
Even a text book lying on the floor is an example of this law. If the book exerts a force of say 10 Newton on the floor then the floor also exerts and equally opposite force of 10 Newton onto the book.
Even when we are standing still on the ground, the ground is actually exerting an equally opposite force exactly equal to our weight.
With these simple examples of Newton’s three laws of motion we can understand that it is something which we can see and apply in our daily lives. Most of the things we do are examples to these three laws.
Hope this article has given you a new perspective in looking at your world and made you understand the three laws of motion better.

Newton's laws of motion
Newton's laws of motion consist of three physical law s that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries, and can

Question:I need to come up with real life examples out of Newtons 3 laws of motion (1 example for each law)
1st law: An object in motion tends to stay in motion, An object at rest tends to stay at rest.
2nd law: Force is equal to mass times acceleration (F=M*A) in simple terms (you need a force to move a mass)
3rd law: Every action has an equal and opposite reaction.
I understand the laws and everything but i just can't come up with a real life example of each one.
Please help mee ! This a for a huge grade in school and my grade can't go down any lower /:
Answers:The examples are all around you.
1) satellite orbiting the earth. Space is a vacuum so once something is set in motion it will continue to move until acted upon by an outside force. Gravity keeps the satellite near the earth but it continues to move around the earth because of the 1st law.
2) You just have to think logically. It requires more energy to move something heavier (more mass) faster (greater acceleration). Ex is running. If you run faster it takes more energy. If you run with a 50 pound weight it requires more energy.
3) If you punch a brick wall your hand will break. This is because the wall exerts an equal and opposite force to your hand.
Question:1st. law. Objects at rest stay at rest and objects at motion stay in motion unless acted on by a force.
2nd law. Acceleration of an object depends on it's mass and the size and direction of the force acting on it.
3rd law. Every action has an equal and opposite reaction force.
An example of how each of these 3 laws is applied in:
Answers:gravity is pushing you down the hill
its being forced up by the rocket engine
you move forward only because your pushing back on the water with your ores
Question:Could someone give some real life examples of Newtons three laws of motion.? Thanks in advance
Answers:Inertia...car skids out of control on a curve and ends up in a corn field.
F = ma...car of mass m accelerates down the freeway when the driver pushes the pedal to the floor.
Balanced forces...you sitting in your chair as you read this answer.
Question:I am doing a science project . Is a girl riding a surf board considered to be Newtons first law of motion ? I have a science Project and isnt a girl riding a surfboard considered to be Newtons first law? & Newtons First law, isnt it An object will stay at rest unless another object will act upon it???
Answers:Theoretically, this is a scenario where the three Laws Of Newton can be applicable.
Anyway, Newton's 1st Law is also known as the Law of Inertia and fora science project, I would suggest a very simple demonstration like so.
Place a block (or any object) on a smooth table. Note that this block is not moving initially. If you apply an external force on it (in other words, push or pull it), the block will obviously move consistent with the direction of the applied force.
If the external force is taken off (i.e., you stop pushing or pulling), the block will simply stop. Another way the block will stop is when something stops it from moving. It could be an impediment or simply anything that will prevent the block from moving.
Hope this helps.
