i need help on Newton's Laws Please?

Question

What is an example of how Newton's Three Laws affect our everyday life? What's a physical example for each of the Newton's Three Laws? Thanx! =D

everybody thanx for your answers tehy were great!!!

Answer 1

Newton's Laws of Motion are three physical laws which provide relationships between the forces acting on a body and the motion of the body, first formulated by Sir Isaac Newton. Newton's laws were first published in his work Philosophiae Naturalis Principia Mathematica (1687). The laws form the basis for classical mechanics. Newton used them to explain many results concerning the motion of physical objects. In the third volume of the text, he showed that the laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

[edit] The Three Laws of Motion
Newton's Laws of Motion describe only the motion of a body as a whole and are valid only for motions relative to a reference frame. The following are brief modern formulations of Newton's three laws of motion:

First law
An object will stay at rest or move at a constant speed in a straight line unless acted upon by an unbalanced force.
Second law
The rate of change of the momentum of a body is directly proportional to the net force acting on it, and the direction of the change in momentum takes place in the direction of the net force.
Third law
To every action (force applied) there is an equal but opposite reaction (equal force applied in the opposite direction).
Another way of stating Newton's third law, an interaction between two objects, is that, if object A exerts a force on
object B, object B will exert the same magnitude force on A, but in the opposite direction.
It is important to note that these three laws together with his law of gravitation provide a satisfactory basis for the explanation of motion of everyday macroscopic objects under everyday conditions. However, when applied to extremely high speeds or extremely small objects, Newton's laws break down; this was remedied by Albert Einstein's Special Theory of Relativity for high speeds and by quantum mechanics for small objects

Answer 2

Actually in real life, the newton's laws contradict the real state. It is all due to frictional force.
I law- every object continues to be in the natural state of rest or of uniform motion until it is acted upon by a certain force.

Eg:- when we throw a ball, it stops due to the force exerted by the Earth called gravity.

II LAW - the rate of change of momentum of an object is directly proportional to the applied unbalanced force.

Eg.: - rate of change of momentum =
m(v-u)/t = ma
it stated that more we apply the force. more is the acceleration produced.
Example is that when we push a car with a greater force, it moves with a much greater speed.

III LAW - to every action there is an equal and opposite reaction.

Eg: - when we fire the gun recoils i.e it takes aback.

I hope that you understood

Answer 3

You should have these in a book.
An object won't change motion without something else happening first. What does it take to start something moving? What does it take to stop something moving? What does it take to change the nature of existing movement/turning force?
F = m*a. What happens when you drop something?
For every action there is an equal and opposite reaction. What happens when forces are not balanced? Something moves or breaks to maintain the balance. If you push against a wall and the wall does not push back with the same force you use, then the wall will move. If the wall uses more force than you, then you will move. Either way it is equal and opposing.

Answer 4

1st law is about the inertia of an object , you can use any object in the outer space as an example. For example an orange in the outer space will move if it experiences a force otherwise it will stay still
2 st law says about the proportion of acceleration to force for example when you push a chair , it will move faster when you push harder.
3st law says that if one thing interacts with another, or if two things interact, the two things have an effect on each other for example when a moving ball hits another still ball they will move maybe in the same direction , or different direction. alternatively they will stay still after hitting

Answer 5

For the 1st law: A chair. It will stay on that spot unless someone either pushes it or pulls it.
2nd Law: If you throw a ball up,it's going against gravity so it's acceleration is lowering and when it comes back down, the gravity's pushing it down so it's speed/acceleration increases.
3rd Law: If we step off a boat onto the bank of a lake: as we move in the direction of the shore, the boat tends to move in the opposite direction (leaving us facedown in the water, if we aren't careful!).

Answer 6

"Newtons Law of gravity predicts that things will always go straight up and spin counter clockwise when you let them go." I want what you are obviously smoking.

Answer 7

ok,let us take up 1st law.imagine you have a toy car which you have placed it on the table.The law says that it does not move untill you [you here is external force] push it . thats it .
