Question

❤.State three laws of motion show that the first law of motion gives the definition of force and the second law of motion give the measure of force.​

Answer 1

Answer:

Newton's First Law

As per first law of motion we know that the object will continue in its state of motion or state of rest until some external unbalanced force acts upon it

It is also known as law of inertia so the object will neither change its speed not it will change in its direction until some unbalanced force acts upon it

Newton's Second Law

As per 2nd law we know that rate of change in momentum of the object is net force on the object

So we know that momentum of object is given as

$P = mv$

so net force on the object is given as

$F = \frac{dP}{dt}$

Newton's Third law

As per Newton's III law for every action there is equal and opposite reaction force. So all forces will act in pairs and for all action forces we will get same magnitude and opposite direction reaction force
