Newton's first law states "Something at rest stays at rest unless acted on by an unbalanced or outside force". "Something in motions stays in motion unless acted on by an unbalanced or outside force".
There are many applications of Newton's first law of motion. Consider some of your experiences in an automobile. Have you ever observed the behavior of coffee in a coffee cup filled to the rim while starting a car from rest or while bringing a car to rest from a state of motion? Coffee tends to "keep on doing what it is doing." When you accelerate a car from rest, the road provides an unbalanced force on the spinning wheels to push the car forward; yet the coffee (which was at rest) wants to stay at rest. While the car accelerates forward, the coffee remains in the same position; subsequently, the car accelerates out from under the coffee and the coffee spills in your lap. On the other hand, when braking from a state of motion the coffee continues forward with the same speed and in the same direction, ultimately hitting the windshield or the dash. Coffee in motion tends to stay in motion.
An everyday example of Newton's second law is when you push a shopping cart with different forces, and you notice that the heavier the cart is or the harder you push it, the faster it accelerates. This is because the acceleration of the cart is directly proportional to the net force applied and inversely proportional to its mass, as described by the equation F=ma.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
Every single object that exists obeys ALL of Newtons Laws
Newtons Second Law was F=ma, means the force(F) acting on object is equal to mass(m) of object times it's acceleration(a).
An everyday example of Newton's first law of motion is when a car comes to a stop without applying brakes. This happens because the car continues to move forward due to inertia until a force (friction or brakes) acts to stop its motion. Another example is when a ball rolling on a flat surface eventually stops due to the force of friction balancing its forward motion.
An everyday event of Newtons second law is riding on a scooter. When you ride on a scooter, and you make your self go, but just let it go, the more mass that you have on the scooter, the greater distance it will go

its not importsnt
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
the second law
The clue is in the question.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
newtons third law of motion
Every single object that exists obeys ALL of Newtons Laws
yea
F = m a
