What is law of newton?

Answer 1

Newton formulated many laws, the ones he is mainly connected with are the laws of motion-

1.First Law : A body remains in a state of rest or uniform motion unless acted on by an external force .So, the body is reluctant to change it's present state and this property of the body is known as inertia. Hence, this law is also known as law of inertia.

*Note : the concept of rest, motion or acceleration is meaningful only when a frame of reference is specified. Newton's first law is a statement about reference frame .

2.Second Law : The product of mass 'm' of a mass point by it's acceleration 'a' is equal to the force acting on it. That is F = ma and it is also stated as the rate of change of momentum is directly proportional to the force .That is F = dP/dt

3. Third Law : When a force acts on a body an equal force acts on another body. That is F12 = -F21

*Note : it should be noted that these forces act on different bodies. If they act on the same body, then there will be no acceleration, because in this case, the net force will beZERO

There is also the law of cooling-the rate of cooling of a body is proportional to the difference in temperature between the body and its surroundings

Also the law of gravitation-the gravitational attraction of a body is directly proportional to its mass and inversely to the square of the distance.

Answer 2

Newton's laws of motion are three fundamental laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object will remain at rest or in uniform motion unless acted upon by an external force. The second law relates the acceleration of an object to the net force acting on it and its mass. The third law states that for every action, there is an equal and opposite reaction.

Answer 3

Newton's principles or laws were developed to describe the relationship between a body and the forces acting on it and the response or reaction of the body to the forces. These laws were developed by English physicist and mathematician, Isaac newton.

Answer 4

The 'newton', named for the 17th Century physicist and mathematician Sir Isaac Newton, is the unit of force in the SI system.

It's defined as 1 kilogram-meter per second2. That means that a constant force of one newton pushing on a 1-kilogram mass will cause the speed of the mass to increase 1 meter-per-second every second.

You feel a downward force of 1 newton when you hold about 3.6 ounces of sand in the palm of your hand.

The standard unit of force is called a newton(N). (1 newton of force will stretch a thin rubber band, or will be what it takes to lift up a D-cell battery). Does this help?

Answer 5

Newtonian physics is more commonly known as Classical Mechanics. It deals with the physics of macroscopic objects not moving near the speed of light.

I.e. It is the physics of things where quantum mechanics and Einstein's relativity do not apply.

It encompasses things like planetary motion, gravity, wind resistance, projectiles, collisions, torque, and such.

Answer 6

Newton's scientific theories depict a deterministic universe in which the state of the universe at any given moment will lead necessarily to a specific, and calculable new state. It has sometimes been described as a clockwork universe, one which runs like a huge machine.
