Are Newton's Laws Stand Alone?

by Eva Fooshee

Do Newton's Laws Stand Alone? (not relying on each other)

Well, in my opinion, no. Each of Newtons Laws works with each.

To prove this, however, you need to be familiar with Newton's Laws, which go as follows:

1) Any object at rest will stay at rest unless acted upon by unbalanced force. The same goes the opposite way, meaning an object in motion will stay in motion (and going the same speed/ direction) unless acted upon by an unbalanced force.

2) force times mass equals acceleration

3) For every action there is an equal and opposite reaction

Newton's Law of Conservation) Energy cannot be created or destroyed.

Okay, now that we have that out of the way your probably wondering how I'm going to prove my claim. Well, if you continue reading I will give you three examples proving my point.

Example One: A Rocket blasting Off

When a rocket (example: Apollo) is first built it'd, of coarse, built in a way that will keep the rocket at rest. So, to make it move, the rocket has to be acted upon by an unbalanced force. This force however come in the form of jet propulsion. However, the unbalanced force wouldn't make a difference without Newtons third law, which, in a way, explains the first law. The jet propulsion is the action and the rocket moving upward is the opposite reaction.

Example 2: A Ball Being Kicked

In the situation above, all four of Newton's laws could be seen, however (because I don't want this segment to be too long and boring to actually bother to read) I will only list and tie together two of Newton's Laws.

When a soccer ball gets kicked, and is put into action, it accelerates. This brings us to think of Newton" second law (see at beginning of flyer), which does happen to come into affect. The force used to kick the ball, times the mass of the soccer ball, does, of coarse, give us the acceleration of the soccer ball. But would that be the case if Newton's Law of Conservation didn't exist? I don't think so. Without Newton's Law of Conservation we could assume that any time anything stopped it lost all energy. If this was, in fact, the case then the soccer ball, when kicked, wouldn't have the potential energy to move, and therefore wouldn't.

Example 3: Tripping

When someone walks and then trips on something, they are acted upon by the force of gravity and the force of whatever they ended up tripping on. This causes them to change the direction and speed of their movement, show that Newton's first law is in place. At the same time, as the person starts to fall, some of the person's potential energy is converted to kinetic energy, showing that Newton's first law, and his Law of conservation work together. But that isn't it, when the aforementioned person hit tripped on whatever they tripped on the reaction was them falling, showing the Newton's 3rd law also comes into play.
