What are Newton's Laws of Physics?

Question

The first, second, and third plus, inertis and centrepital force.

Answer 1

1st law
Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it

2nd law
The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.

3rd law
For every action there is an equal and opposite reaction.
This law is exemplified by what happens 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

inertia--The tendency of a body to resist acceleration; the tendency of a body at rest to remain at rest or of a body in straight line motion to stay in motion in a straight line unless acted on by an outside force.
or
That property of matter which manifests itself as a resistance to any change in the motion of a body. Thus when no external force is acting, a body at rest remains at rest and a body in motion continues moving in a straight line with a uniform speed (Newton's first law of motion). The mass of a body is a measure of its inertia

centripital force--Any motion in a curved path represents accelerated motion, and requires a force directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has the magnitude

f=mv^2/r

Answer 2

Newton's First Law or Law of Inertia
- in the absence of a force, when viewed in an inertial reference frame (at rest or moving at a constant rate), an object at rest will remain at rest and an object in motion will maintain its motion
- inertia is the property of an object to resist a change in its state of motion

Newton's Second Law or Law of Acceleration
- viewed in an inertial reference frame, the acceleration of an object is (a) directly proportional to the net force acting on it, (b) in the same direction as the net force and (c) inversely proportional to its mass
- Net force = Mass x Acceleration

Newton's Third Law or Law of Action and Reaction
- for every action, there is an equal but opposite reaction
- forces always come in pairs and they're equal in magnitude, but opposite in direction
- it's important to note that the action and reaction forces do not cancel each other out since they're acting on two different objects

Answer 3

There are only really two which you need to concern yourself with. The second and the third, since the first is essentially a special-case statement of the second.

The first states that an object will continue at a constant velocity unless acted on by a net external force, you will move at the same speed in the same direction until a net external force acts on you.

The second law states that the acceleration of an object (time rate of change of velocity) is proportional to the net external force on the object.

F = ma

If you set that force equal to zero you will see that for all massive objects (things that have mass) there must be no acceleration (the first law).

The third law talks about the interaction between two objects. If object one acts on object two with a force F, then object two must act on object one with a force F in the opposite direction.

F(12) = - F(21)


Centripetal force essentially says that if you are moving in a circle with a velocity v, you must be experiencing a force directed toward the middle of the circle proportional to your velocity squared. It is a consequence of Newton's second law.

F = m v^2 / r

Answer 4

Law 1.
A body continues to be in a state of rest or state of uniform motion until and unless it is subjected to an UNBALANCED external force.

Law 2.
The force applied on a body is directly proportional to the rate of change of momentum of the body,and this change takes place in the direction of the applied force.

Law 3.
to every action there is always an equal and opposite reaction.

If this has been asked just for the sake of asking then i must say it was a deadly joke.
Many of us know how to write them on paper but certainly very few can explain life with the help from this laws.

Answer 5

????? you do not realize the real problem right here... If God created the international, this international ought to stay authentic for all the people's understand-how... Einstein, or Newton or the different philosopers and scientists, merely DID THE area of researching the guidelines of physics.......... the real theory and the significant purpose of researching those physics guidelines, is to stay with those guidelines for the sake of EASING our on a daily basis lives. The guidelines did not come first earlier God. How ought to you ask such irrelevant question..

Answer 6

I law of motion: "Every body continues in its state of rest, or of uniform motion in a straight line, unless it is compelled to change that state by forces impressed on it"
II law of motion: "The acceleration given to a body by a force applied to it is directly proportional to the force and is in the same direction as the force and inversely proportional to the mass of the body"
III law of motion: " To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts"
Law of gravitation: "Every particle of matter in this Universe attracts every other particle with a force, that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them"
Principle of Inertia implied in I law of motion: 'Tendency of the body to continue in its state of rest or of uniform motion in a straight line unless and until an external force acts upon it'
Centripetal force: The radial force directed toward the center experienced by a body in Uniform circular motion. This can be calculated with the help of II law of motion
