Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. Let's break this law down by defining some key terms. Velocity is the speed of an object in a specified direction. An unbalanced force is an external force that changes the motion of an object. When an object is at rest or moving at a constant velocity, all the forces acting on it are balanced. The First Law can also be call Inertia.

The Second Law is concerned with relating acceleration to mass and net force.
Newton's second law of motion explains how an object will change velocity if it is pushed or pulled upon.Firstly, this law states that if you do place a force on an object, it will accelerate (change its velocity), and it will change its velocity in the direction of the force. So, a force aimed in a positive direction will create a positive change in velocity (a positive acceleration). And a force aimed in a negative direction will create a negative change in velocity (a negative acceleration).

Every Action has an Equal and Opposite Reaction.This is the third of Sir Issac Newton's laws of physics, and one that is very important to space flight. Here's how it works. If you push on anything, it pushes back on you. That's why if you lean against the wall, you don't just fall through it. The wall pushes back on you as hard as you push on it, and you and the wall stay in place. If you throw something, you put more force behind it than just leaning on it, so it pushes back with more force. This is hard to observe, because usually, if you throw something away from you, the friction between you and the floor makes resistance to keep you in place.
