First Law: Every object continues in a state of rest or in a continuous motion in a straight line, except in so far as it is compelled to change that by forces exerted upon it.

What that means: If you shoot an arrow at a target, it will keep going straight without going down or up unless it is affected by gravity (or your friend Jim) which it will be. Gravity is the force being exerted upon the arrow, pulling it down to the ground.

Second Law: Acceleration is produced when a force is acts on a mass. The greater the mass of the object being accelerated, the greater the force needed to accelerate the mass.

What it means: If you were pulling a fat guy up onto the top of a cliff from the bottom, you would need to pull harder than if you were pulling a skinny guy onto the top of a cliff.

Third Law: Objects interact such that for every force exerted on one, there is an equal and oppositely directed force on the other.

What it means: Say you were sitting in a chair with wheels on the bottom next to a wall. If you push against the wall, you will be pushed backwards. The equal force is where you are pushed back with the force that you pushed on the wall. The opposite force is where you were pushed away from the wall.
