Question

what is the newton's three laws explain

Answer 1

I think 3law of Newton's is
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine.

Answer 2

Newton’s First Law of Motion states that objects with balanced forces acting on them will stay at rest or stay in constant motion.

Newton discovered that objects will continue to do what they are doing until an unbalanced force acts on the object. From this we can determine that:

forces act on objectsforces cause changes

We can also determine that forces acting on an object can change the shape of the object, the speed of the object, and the direction in which the object is moving.

Newton’s Second Law of Motion states that when an unbalanced force acts on an object:

the direction of the object's acceleration is the same as the direction of the unbalanced forcethe magnitude of the object's acceleration varies in direct proportion with the size of the unbalanced forcethe magnitude of the object's acceleration varies inversely with the mass of the object

The unit of force is called the newton (N).

1 newton is defined as that unbalanced force which produces an acceleration of 1 m/s2 when it acts on a mass of 1 kg. An average-sized apple weighs about 1 newton.

Newton's Second Law of Motion can be written as the following relationship:

F = ma

where:

F = unbalanced force

m = mass

a = acceleration

Note that when you use this relationship, F always stands for unbalanced force.

Newton's third law concerns equal and opposite forces. It states that, "If A exerts a force on B, then B exerts an equal but opposite force on A."
