First law (Law of Inertia)
If could push an object and no forces acted on it this object would move with constant speed forever (The sum of forces on the object is zero). If the object remains at rest we need a force to move it. We need a force to make an object that moves to move faster or to slow it down.

Second Law
If the force is applied to the object or the resulting force not equal to zero the object will move with acceleration inversely proportional to its mass and directly proportional to the resultant force.
a=F/m or F=ma
Newton actually suggested a change of momentum p with respect to time t.

F=mdv/dt
F - force
m – mass
t – time (dt – change in time)
v – velocity (dv – change in velocity)

Third law
If you push with a certain force on the wall the wall will push right back (tough wall!) with the same force. If push any object you feel resistance or the force of that object pushing back. A rocket is another example of the Third Law. As exhaust gasses escape the nozzle they push the rocket in the apposite direction.

I hope it helps
