Newton's laws of motion describe the motions of objects
when they have forces acting on them.
Law #1:
If there's NO force acting on an object, then the object keeps moving
the same way it's moving. Its speed and direction don't change.
If you see an object changing its speed or direction, then there
must be force acting on it. It can't do that all by itself.
Law #2:
If there IS any force acting on an object, then the object's speed
or direction must change.
The rate at which it changes is called "acceleration". The acceleration
is proportional to the strength of the force (stronger force causes more
acceleration), and inversely proportional to the object's mass (objects
with more mass have less acceleration; they need more force to produce
the same acceleration).
Law #3:
Whenever one object pushes on another object, the second one
pushes back on the first one, with exactly the same size of force.

Well, Newton created his three laws based on the studies made by the early scientists Aristotle, Galileo, and Copernicus.
Newton's First Law, pretty much a restatement of one of Galileo's ideas, is that a force is not needed to keep an object in motion. Newton decided, (with Galileo's help) that, "Hey... an object at rest stays at rest, but also has inertia so it can move in a continuous path or move on its own without a push or pull!"
Newton's Second Law, one that Newton came to conclusion with himself, is that when we move something, acceleration is created. But the object can't go as fast as we push or pull it, because its mass is in the relationship of an object's mass, the total net force, and acceleration.
Newton's Third Law is that you cannot touch without being touched! For example, in order to touch someone's arm or shoulder, it always touches you back. If you put force onto a wall by leaning on it, it gives that same force right back!
There's so much more you can learn about these laws, but here are the basics and I hope this is what you were looking for! :)
