Question

Newtons law of motion​

Answer 1

Newtons laws are as follows : 1⃣ it states that the tendency of a body to continue in its state of rest or uniform motion unless and until some external unbalanced force is applied in a straight line 2⃣ the acceleration of the object as produced by the net force is directly proprtional to the magnitude of that net force and inversily proportional to their product of their masses in the same direction as the net force acts 3⃣ for every action there is an equal and oppsite reaction or action and reaction are equeal and opposite between the two bodies                                                                                                                                                 HOPE IT HELPS YOU

Answer 2

$\huge\textbf{Newton's}$

$\underline{\underline{\huge{\textbf{Law\:of\:Motion\::}}}}$

$\textbf{1) Law of Inertia : }$

It is Newton's First law.

According to it an object at rest remains at rest, an object in uniform motion remains in uniform motion until or unless external force applied on them.

$\textbf{2) Law of Force :}$

It is Newton's Second law.

According to it the rate of change of linear momentum is directly proportional to the external force applied.

F α $\dfrac{dp}{dt}$

F = k $\dfrac{dp}{dt}$

Now,

p (momentum) = mv

So,

F = k $\dfrac{d(mv)}{dt}$

F = k $\dfrac{md(v)}{dt}$

F = k ma

(As, $\dfrac{dv}{dt}$ = a)

Experimentally k =1

So,

$\textbf{F = ma}$

$\textbf{3) Action - Reaction Law :}$

It is Newton's Third Law.

According to it, for every action there is equal and opposite reaction. [Equal in Magnitude but opposite in Direction.]
