Define Newton's 1st laws,Newton's 2nd law and Newton's 3rd law.?

Question

Answer

Newton's 1st law:-

'An object remains in a state of rest or of uniform motion in a straight line unless compelled to change that state by an applied force'.

Newton's 2nd law:-

'The rate of change of momentum of an object is proportional to the applied unbalanced force in the direction of force'.

Newton's 3rd law:-

'For every action, there is an equal and opposite reaction'.

Answer

Answer

1st Law : An object will continue to be in uniform motion or at rest untill and unless an external force and unbalanced force acts on it and changes it's states of motion!

2. the acceleration produced in a body is directly proportional to the the force applied , in the direction of force and is inversely proportional to the mass of the object !! a = f/m ; f = m× a

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

Answer

Newton's First Law:
Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity unless acted upon by an external force. In simpler terms, an object will not change its state of motion unless a force is applied to it. This law essentially describes the concept of inertia, which is the tendency of an object to resist changes in its motion.

Newton's Second Law:
Newton's second law of motion relates the force acting on an object to its mass and acceleration. It can be mathematically expressed as F = ma, where F represents the force applied to the object, m is the mass of the object, and a is the acceleration produced. This law explains how the motion of an object changes when it is subjected to an external force. According to this law, the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. In simpler terms, the force exerted on an object determines how much it accelerates, and the object's mass determines how much force is needed to accelerate it.

Newton's Third Law:
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This law explains the relationship between the forces acting on two interacting objects. When one object exerts a force on a second object, the second object simultaneously exerts a force of equal magnitude but in the opposite direction on the first object. These forces are known as action and reaction forces. It is important to note that these forces act on different objects and not on the same object. The third law of motion reflects the conservation of momentum, as the total momentum of a system remains constant when two objects interact.

In summary,
- Newton's first law states that objects will remain at rest or in motion unless acted upon by an external force.
- Newton's second law relates the force, mass, and acceleration of an object, explaining how the motion changes when a force is applied.
- Newton's third law states that for every action, there is an equal and opposite reaction, describing the relationship between forces acting on interacting objects.

Answer

Newton's 1st law-A body at rest will remain at rest and a body in motion will remain at uniform motion acted upon unbalanced force.
Newton's 2nd law-The produces as mass and asseleration is equal to the force.
Newton's 3rd law-For every action their is equal and opposite reaction.
