Question

how can you deduce Newton's first law of motion from Newton's second law​

Answer 1

• Newton's First Law : The object will not change its state unless an external force acts on it.

• Newton's Second Law : The force on an object is equal to its mass times its acceleration.

• Newton's Second Law : When two objects interact, they apply equal and opposite forces on each other.

According to 2nd Law,

$\boxed{\bold{\sf{F=ma}}}$

$\sf{\implies F=m\dfrac{(v-u)}{t}}$

If Force = 0,

$\sf{\implies v=u}$

Which means that the object continues to move with uniform velocity if no force is applied.

If Force and Initial velocity is 0 then Final velocity is also 0.

Which means the object will stay at rest.

As we know according to 1st law, it can be related.

Hope it is clear!
