Newton's Laws

Newton’s First Law of motion is true because an object would never stop unless something would be added to it to stop the object like gravity, or if all of sudden the object ran into a wall, which would then stop the object from moving.

Newton’s Second Law of motion is true and applies to the physical world because a ball, or any object that has the ability to move, would stay at the same speed of falling or, rolling down a hill.But then as the steeper the hill gets the speed of the object would gain, and this is created by gravity pulling down on the object trying to make it get to a flat surface which will then stop the object once it runs out the momentum which was given to it from going down the hill.

Newton’s Third Law Of Motion is true and applies to the physical world because if you step onto a boat it will rock the boat in the water in a direction, but then if you’d step into the boat at a different location it would cause a different effect moving the boat in a different direction then before.
