In this last week of Physics, we learned more about tensions and pulleys. Pulleys are objects that changes the direction of a force. In this picture, although there are no pulleys, there is a tension. In this picture, my dad's Blazer is pulling my uncle's tow-truck with a string. In class I have learned the saying "1 string, 1 tension". This means that if there's 1 string, there's 1, equal tension. That means that the tension pulling on my dad's blazer and the tension pulling on my uncle's tow truck are the same, equal tension. Also, if I wanted to find the acceleration of either vehicle, I would just find the acceleration of "da whole ting" because they are the same.

In our everyday lives, there are objects everywhere around us. On each of these objects, there are forces acting upon them and go on unnoticed. For example, look at this tiny skateboard. One force acting upon it is its weight, or mass x gravity (mg). This object isn't moving, thus it isn't accelerating. With that said, that means that this object is at static equilibrium. Another force acting upon this object is the normal force (N) which is from the surface it's sitting on, (in this case the carpet). Friction, or the contact force between two objects also exist between the skateboard and the carpet.

This week of Physics, we have been introduced to "force". Force is a push or pull. There are two types of force: contact, and at a distance. Contact force is a force that uses a physical contact between objects. For example, if I push my chair across the room, I am providing a contact force because there's physical contact between me and the chair. The other type of force, at a distance, is a force that has no contact. One of the most obvious at a distance forces is gravity. So, going back to the chair. I am providing physical force, but that's not the only force that is acting upon it. Gravity is also there acting upon it, pulling it down to the ground and keeping the chair from floating all over the place.

Last week of Physics, one of the most important things I learned in class was the "Vegas Rule". The Vegas rule is: whatever happens on the x-axis, stays on the x-axis. This saying is also the same for the y-axis. What this means, is that the x and y axis of an object are independent and don't affect each other. For example, if I were to throw this pool stick horizontally on the x-axis with no force directed to the y-axis, the  time it would take to fall would be the same as if I just dropped the pool stick directly from the same height. This is because what happens on the y-axis stays on the y-axis. Just because I would throw the pool stick horizontally on the x-axis, it doesn't affect the velocity, acceleration or anything dealing with the y-axis. Although it would be traveling on the x-axis, it would also be accelerating down the y axis with the same velocity as if it were directly dropped. The only difference is, the one being dropped is not traveling on the x-axis.
