Newton's three laws of motion where created when an apple fell on his head. The first law of motion is when an object is in motion, it will always stay in motion. On the other hand when an object is at rest,it will always stay at rest unless a force acts on it. when an object is moving, all in it and on it will move in the same speed. If the object suddenly stops, the other objects will keep on moving until stopped by another force acting on it. Even though it was said by newton if an object moves, it will remain moving does not happen in our world is because of friction. Friction is produced when two rough surfaces rub together.
The second law of motion is when an object has an unbalanced force acting on it will accelerate in the direction of that force. An example is when you are sitting on the top of a slide. You will not move because gravity is pulling you down, on the other hand the slide is pushing you up which cancels out the forces. But if you push, you will then slide down because even though the air resistance is acting on you along with friction,the majority of force is gravity because you are on a slope and so you will use your mass to gain more speed and gravity advantage.
Newton's third law of motion is forces always occur in equal and opposite pairs. So if you are pushing a door, the door will move and you will move as well. That does not happen because of the friction between our feet and the floor which combines your mass with the floor's or building's mass. However, if you tried it with your roller skates, you will go back because there is less friction happening since roller skates have less rough surfaces and since its a small wheel, there is less surface touching ot making a contact with the floor which reduces the amount of friction.
