<caption>I had a native graph here, but it works nicely on Desktop and not mobile. You can toggle it in developer tools.</caption>
<caption>Mobile optimization for native graphs is not the move right now. So here is Desmos</caption>
<!-- <canvas id="myFirstChart" width="20%" height="10px"></canvas> -->
</ul>
<br>
<ul>
<li>Let's assume it is a velocity, time graph</li>
<li>Seems like the object is moving at an increasing velocity with a constant positive acceleration</li>
<li>Finding the area underneath the line gives you displacement.</li>
</ul>
</ul>
<iframe src="https://www.desmos.com/calculator/texsbmjykj?embed" width="100%" height="500px" style="border: 1px solid #ccc" frameborder=0></iframe>
<ul>
<li>Find area underneath till a second later. so area of a triangle with a base and height of 1</li>
$$\frac{1}{2}*b*h = \frac{1}{2}*1*1 = 0.5 meters$$
<li>You can also do this using the following equation</li>
$$X = \frac{1}{2}(V+U)T$$
<li>Where V is final velocity and U is initial velocity. A better way to write it would be </li>
$$X = \frac{1}{2}(V_f+V_i)T$$
<li>Plug</li>
$$X = \frac{1}{2}(1+0)1 = 0.5 meters$$
</ul>
<p>Now given a position time graph. You can find the slope to get the velocity</p>
<ul>
<li>Assume the same graph is used and you want to find velocity in 2 seconds:</li>
$$M = \frac{rise}{run} = \frac{Y_2-Y_1}{X_2-X_1}$$
<li>Using the coordinates (0 seconds,0 meters) and (2 seconds,2 meters)</li>
$$M = \frac{2-0}{2-0} = \frac{2}{2} = 1$$
<li>We find that the object had a velocity of 1m/s during the 2 second mark</li>
<li>Which makes sense since the object traveled 2 meters in 2 seconds. </li>
<li>This also works when the object is in a state of deceleration</li>
</ul>
<br>
<p style="color:#fcc02e">Acceleration, Time Graphs</p>
<ul>
<li>Whew</li>
<li>Let's use the graph above as well here. A constantly increasing line for a constantly increasing acceleration</li>
<li>Since it is increasing by a factor of 1 each second the acceleration is 1 meter/per second/for every second (1m/s/s)(1m/s^2)</li>
<li>They allow us to find the area underneath the graph in order to get the velocity in the given timeframe.</li>

<li>U = Change in internal energy</li>
<li>Q = heat added</li>
<li>W = work done</li>

<li class="y">Expansion of the first Law:</li>
<ul>
<li>The first law has several principles</li>
<ul>
<li class="y">Conservation of Energy</li>
<li class="y">A concept of internal Energy and it's relationship to temperature</li>
<ul>
<li>Let's say a system has a definite temperature, then its total energy would be distringuishable in three ways. </li>
<li>If its moving it has <a href="" class="y">Kinetic Energy</a></li>
<li>If it is not moving but could move, such as a ball in mid-air then it has <a href="" class="y">Potential Energy</a></li>
<li>Then it has its own internal energy</li>
<li>All of this can be presented using the equation</li>
</ul>
$$\color{#fcc02e} E_{total} = KE_{system} + PE_{system} + U_{system}$$
<li class="y">Work</li>
<ul>
<li>Work is a measure of energy transfer</li>
<li>Usually measured in joules</li>
<li>Ap Physics Equation:</li>
$$\color{#fcc02e} \Delta E = W = F_{||}D\cdot cos$$

Matter can flow into and out of

Examples
</li>
<ul>
<li>A stove top heating a pot of water. Energy is transferred between the stove,pot, and water but since heat can be lost into the air we consider it an open system.</li>
<li>
</li>
</ul>
</ul>
</li>
<li>
<p class="y">Closed Systems</p>
<ul>
<li>
A system which can not transfer energy to its surroundings.
</li>

<p class="y">Isolated Systems</p>

<li>
Nothing enters, nothing leaves
