Newton's Laws

Newton's First Law 

The Law of Inertia: An object in equilibrium will remain in equilibrium until another force acts upon it.

Tl;dr:

Things like to move until stopped. Things don't like move if they aren't already moving...Objects tend to be lazy.

Newton's Second Law

Newtons Second Law is the relationship between an objects mass and acceleration to the force. This is know as the equation F=ma. Force has a direct relationship with acceleration. This means an object will accelerate faster if more force is enacted upon the object. This is shown in the videos below. The first being a much greater force applied to an object of the same mass.

Force also has a direct relationship with mass. The greater the mass of an object, the more force required to move it. This is shown in these videos below.

Mass and Acceleration have an inverse relationship. This means that the higher mass of an object, the slower it will accelerate. This is shown in the video below.

tl;dr

Pushing things harder will make them go faster. Pushing something heavy will move slower than pushing something light.

Newton's Third Law

Newton's third law is that every action has an equal and opposite reaction.
This means that for every action a force will react to it with equal force in the
opposite direction. An example of this would be jumping off of a boat.
 When you jump off, the boat is pushed in the opposite direction from where you jumped.

 

 

 

 

If it wasn't true... (The First 6 Seconds of this video):

 

This is theoretically what is happening. Fn is higher than Peeta's Fapp, which is impossible given Newton's Third Law! (For the story's continuity, I guess we are to suppose the force field uses a field force to push back against Peeta instead of the Fn of the surface of the force field.)

tl;dr

Don't watch the Hunger Games.
