Used Tracker motion analysis today to help us understand more about how projectile motion works. The video below shows how to use the autotracker function to analyse the motion of the Angry Bird.

We used the analysis to figure out how the horizontal and vertical motion of the bird changed over time. We also calculated the approximate length of Angry Bird required to give an acceleration similar to gravity. The question sheet below was used as a guide.

We started off with the simplest type of projectile - those that are projected horizontally. They therefore have an initial vertical velocity of zero so are pretty much the same as our calculations on bouncing balls and the like.

Things get a little more complicated when you launch projectiles into the air at an angle because the initial vertical velocity is no longer zero. If this is the case then you must think about the horizontal velocity and the vertical velocity separately.

We draw vector diagrams to simulate what we see in the real world. I think some people still don't get this.

As I see it, there are two main rules when drawing vector diagrams:

1. Join your vectors 'tip to tail' 2. Use your common sense!

If the resulting velocity, displacement or force looks wrong then use your common sense. Th diagram is only showing you what will happen if you put these two velocities together or these two forces together.

When we have more than one uncertainty to deal with, we need to choose which one to take into account for our final answer. To do this, we use the value that has the greatest percentage uncertainty.

The percentage uncertainty is expressed as a percentage whereas the absolute uncertainty is written as a number.
