<p>The following topics are covered in this chapter.</p>
<ul data-class="ListBulleted"><li>
Define position relative to a reference point and understand that
position can be positive or negative

<h1>Vertical Projectile Motion</h1>
<div class="teachers-guide" data-unknown="true"><div class="title"></div>
<p>Notes</p>
<p>The following topics are covered in this chapter.</p>
<ul data-class="ListBulleted"><li>
Explain that projectiles fall freely with gravitational acceleration 'g'.
Where g = 9,8 m.s-2 near the surface of the Earth
</li>
<li>
Know that projectiles take the same time to reach their greatest height
from the point of upward launch as the time they take to fall back to
the point of launch
</li>

<h1>Graphs of Motion</h1>
<div class="teachers-guide" data-unknown="true"><div class="title"></div>
<p>Notes</p>
<p>The following topics are covered in this chapter.</p>
<ul data-class="ListBulleted"><li>
For either horizontal motion or vertical motion with constant acceleration:
</li>
<li>
Draw position vs time, velocity vs time and acceleration vs time
graphs for one dimensional motion
</li>
<li>
Interpret graphs of motion:
<ul data-class="ListBulleted"><li>
- Determine the velocity of an object from the gradient of a
position (or displacement) vs time graph
</li>
<li>
- Determine the acceleration of an object from the gradient of a
velocity vs time graph
</li>
<li>
- Determine the displacement of an object by finding the area
under a velocity vs time graph
</li>
