what is the first second third law of motion?
232783
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. ... The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

Newton's second law of motion states that acceleration is directly proportional to net force when mass is constant… and that acceleration is inversely proportional to mass when net force is constant…

Force is mass times acceleration, or F= m x a. This means an object with a larger mass needs a stronger force to be moved along at the same acceleration as an object with a small mass. This is Newton's Second Law of Motion.

The larger the mass of a moving object, the less readily it moves. According to Newton's second law of motion, the acceleration that the object experiences is inversely proportional to its mass, and you can calculate this acceleration from the object's change in speed over a set amount of time.

Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

The third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction: FA = −FB. The third law means that all ...

Newton's second law of motion provides an explanation for the behavior of objects when forces are applied to the objects. The law states that external forces cause objects to accelerate, and the amount of acceleration is directly proportional to the net force and inversely proportional to the mass of the object.

In case of uniform acceleration, there are three equations of motion which are also known as the laws of constant acceleration. Hence, these equations are used to derive the components like displacement(s), velocity (initial and final), time(t) and acceleration(a). ... The three equations are, v = u + at.

Newton's second law can either be expressed as "resultant force = mass × acceleration" or "The acceleration of an object is directly proportional to the resultant (or net) force, in the same direction as the force, and inversely proportional to the mass of the object."

Newton's laws of motion relate an object's motion to the forces acting on it. ... In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. ... If that velocity is zero, then the object remains at rest. If an external force is applied, the velocity will change because of the force.

Newton's third law relates action and reaction forces. ... He noticed that forces always act in pairs. states that every time one object exerts a force on another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.

Newton's 2nd Law: It states that the acceleration of a body is directly proportional to the external force experienced by that body. F is directly proportional to the acceleration of the body. F=ka. where K is the constant of proportionality which is actually the mass of the body so the equation now becomes.

Newton's 2nd law states that if a net force acts on an object, it will move at constant velocity. For a constant mass the acceleration of an object is directly proportional to the applied force. ... The momentum of an object remains the same unless an unbalanced force acts on it.

We can give Newton's first law in vector form: →v=constant when→Fnet=→0N. This equation says that a net force of zero implies that the velocity →v of the object is constant. (The word “constant” can indicate zero velocity.)
