 ===== Friction =====
-Friction is a force caused by the collision of surfaces that are inherently uneven. It is mathematically defined as $F_r = \mu F_n$ where $F_r$ is friction, $F_n$ is the normal force((opposing force of weight when object is resting on a surface)), and $\mu$ being the coefficient of friction(([[physics:newtons_laws_of_motion|Newton's second law]] is useful here if you want to find the friction coefficient given an acceleration without mass present)).
+Friction is a force caused by the collision of surfaces that are inherently uneven. It is mathematically defined as $F_r = \mu F_n$ where $F_r$ is friction, $F_n$ is the normal force((opposing force of weight when object is resting on a surface)), and $\mu$ being the coefficient of friction(([[physics:newtons_laws_of_motion|Newton's second law]] is useful here if you want to find the friction coefficient given an acceleration without mass present)). The coefficient of friction is a uniform value((0-1 linear value)). There are two types of friction.
+==== Static Friction ====
+This type of friction prevents an object from sliding against another surface parallel to the contact area.
+==== Kinetic Friction ====
+This type of friction slows an object instead of preventing its movement. Direction is opposite to the object's net force.
 ===== Tension =====
-FIXME Check the last few sentences to see if they're valid
+See: [[physics:solving_tension_problems|Solving Tension Problems]], also [[physics:incline_plane|Solving Incline Plane Problems]] for Tension on an incline plane.
+Tension is a force that a rope((/string/chain)) exerts pulling one object to another.
+==== Finding Acceleration ====
+The acceleration of tension can be calculated by summing the forces of each object under tension by the sum of their masses(($a = \frac{\sum F}{m}$ where $F$ are the forces and $m$ is the total mass of the objects)).
+=== Force of Tension ===
+FIXME No clue if this is right, disregard if you're doing something important
+You can use [[physics:newtons_laws_of_motion|Newton's Second Law]] (($F_{net} = ma$)) to calculate the force of tension, with $F_{net}$ being the sum of all forces in the system ($\sum F$), $m$ being the mass of the two objects in tension, and $a$ being the value calculated before.
-Tension is a force that a rope((/string/chain)) exerts pulling one object to another. The acceleration of tension can be calculated by summing the forces of each object under tension by the sum of their masses(($a = \frac{\sum F}{m}$ where $F$ are the forces and $m$ is the total mass of the objects)). From there, you can use [[physics:newtons_laws_of_motion|Newton's Second Law]] (($F_{net} = ma$)) to calculate the force of tension, with $F_{net}$ being the sum of all forces in the system ($\sum F$), $m$ being the mass of the two objects in tension, and $a$ being the value calculated before.
+==== From Weight and Net Force ====
+Tension can also be associated as equal to the net force of the system minus an acting force, typically weight $F_{net} = T - W$.
