1st-An object in motion will stay in motion unless acted upon by an outside force

2nd-Force equals mass times acceleration

3rd- Any action will have an equal and opposite reaction

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.

Newton's 1st Law: An object at rest tends to stay at rest unless acted upon by an outside force, likewise, an object in motion tends to stay in motion until acted upon by an outside force.

First Law:
Newton’s First Law of Motion, or the Law of Inertia, states that an object at rest stays at rest unless acted upon by an unbalanced force, and an object in motion stays in motion unless acted upon by an unbalanced force. An object is able to stay at rest as long as the force that is applied is balanced with the force of the static friction. In our video below, the force Pierre is applying to the object is balanced with the force of the static friction of the object. If the forces were unbalanced, then the object would’ve moved. The other part of the law, stating that an object in motion will stay in motion unless acted upon by an unbalanced force, is shown in the second part of the video below. Chase, who is the object that is in motion, continues to stay in motion until Pierre, who is the unbalanced force, runs in to him. If Pierre was not there or if he applied less force than Chase, then Chase would’ve stayed in motion until he met another unbalanced force.


Second Law:



 Newton’s Second Law of Motion states that an object will only accelerate if there is unbalanced force acting on it. The unbalanced force is able to speed up the object, as long as the force is not balanced with the force of the mass. Featured in the video below, Pierre applies a force that is greater than the force of the mass, enabling him to accelerate the object. The second law of motion also pertains to the angle of the force you are applying. Also in the video, Chase shoots the basketball with a greater applied force than the mass, creating unbalanced force, but shoots the basketball with a poor angle, causing him to miss the shot. As Chase increases the angle of the shot while keeping the same applied force, he is able to make the shot. Another aspect of Newton’s second law states that the greater the force applied on the object, the greater the distance the object covers. In our video, this is shown when Jack punts the football. He punts the ball with an applied force great enough to cause the object to move, but the object does not go very far. As he increases the applied force, the object travels a greater distance. The final aspect of Newton’s second law relates to the time in relation to the force. In our video, Nate first exerts the force for a short period of time, causing him to barely move the object upwards. Then, as Nate exerts the force for a longer period of time, the object is able to go farther upward.



Third Law:
Newton’s Third Law of Motion states for every action there is an equal and opposite reaction. There are many examples of this law and we chose to demonstrate it by having Chase hit the ping-pong ball against the other half of the table. As the ball hit the table, it bounced back with an equal amount of force in the opposite direction that the ball came in. If this law were not true, then many sports would not be able to be played. Shown in our video, Chase demonstrates what would happen if the law wasn’t true by dropping a ping-pong ball on the ground. As he drops it, the ball does not bounce back up but just stays on the ground.
