<h1 class="center">Projectile Animation</h1>
|
|
|
|
<p>A projectile is an object fired or thrown by force. Play with the sliders to see how a projectile moves:</p>
|
|
<script src="images/projectile.js"></script>
|
|
<script type="text/javascript">projectileMain();</script>
|
|
<p> </p>
|
|
<h2>Parabola</h2>
|
|
<p>When drag is zero the projectile's path is a <a href="parabola.html">parabola</a>.</p>Try different angles, which angle takes the projectile furthest along? So what angle should you throw at if you want a ball to go far away?<br><br>Can you hit the same spot using different power/angle combinations? <br>
|
|
<h2>Drag</h2>
|
|
<p>A moving projectile gets slowed down by the air (or water etc) that it moves through. This is called "drag", and is actually a complicated subject.</p>
|
|
<p>Here we just use the simple <b>approximation </b>that drag is proportional to the square of the velocity.</p>
