#### Transcript of The Beauty of Movement

Tracker will do it for you!
Eleanor is keeping the camera still by using a tripod, and without any zooming or tracking.

Each bounce takes about a second, and the video capture frame rate is 30 frames per second.

The first set of video captures is from frames 1 to 94. We have tracked the white badge on Hannah’s polo-shirt, and the graph of y against t shows three nice bounces – each with a bit more height than the one before.

If we track again from frames 34 to 57 we have captured the portion of the middle bounce where Hannah is in the air and not in contact with the trampoline.

The graph now looks like a single smooth curve. The only force acting on Hannah is that due to gravity – and Sir Isaac Newton found that the theoretical shape of the height against time graph should be that of a quadratic function, called a `parabola’.
Take a look at this wonderful serve. Could you capture this movement, analyse and find a figure for gravity?
Or you can just admire the serve!
and Ronaldo...Google how he takes his free kick - he's a very, very clever person!
The Theory – don’t worry if you don't get this☺

If you drop a bouncing ball and track its vertical velocity on Tracker, you can then analyse the data with Tracker!

So we hope to have shown how we can make powerful hardware and software technology accessible to all!

Take a look at the kick next (don't blink or you'll miss it:-)
NB Its quite long - and one of four videos...but it's very impressive
Just remember the 9.81
Tracker analyses the data...
..and you can get a figure for gravity...

The Beauty of Movement - or Newton, Gravity and Tracker.

This project provides a well-tested, educationally proven activity to take into schools. It requires no specialist equipment. It can be used by teachers, STEM Ambassadors, parents and also pupils who act as mentors to the students:

The project offers either a single 2-hour activity or four 2-hour activities in which pupils are asked to work in teams, engage in hands-on activities capturing movement of their choice in the form of video clips, learn how to use the powerful, free, open-source Tracker software to capture and analyze these...and come up with an estimate of g (Gravity).

As well as appealing to technologists, this activity is also aimed at NON-technology specialist adults and children offering an opportunity to build confidence and self-belief.

Tracker is amazing free software to capture and analyse movement.

Hothousing is a creative, intense workshop experience used in industry to develop innovative ideas and solutions. The constant time pressure has been found to be key to doing a lot in a very short timescale – and most people find it fun too☺

You will split into 5-people teams. You will address a challenge – you can interpret the question as you wish. You will then use cameras to record ball movement then Tracker to capture and analyse the movement. You will then be asked to present your ideas including your estimate for g.

Mentors/experts will help you as requested BUT it is up to you students to consult them if needed. You must involve ALL members of your team. It is NOT the responsibility of the mentor to lead the group. It is your challenge and we are interested in how you approach it…and above all the ideas you generate!

Here are the instructions to the pupils:
And here is the agenda
Here is the agenda - it could take 50-minutes to 2-hours
So to get the ball rolling, we show short clips from a footballer and tennis player - we can discuss horizontal, vertical movement, gravity, spin, etc etc
We then set the challenge, ask the students to get into groups and report back in three minutes! Feedback is given and received.

Agenda
The mentor 'teaches' Newton and Gravity as we will see in the next section:
Students then just 'get on with it'. The mentor is available to help if asked.

In this section, you will see how to import a clip into Tracker and analyse it...plus some examples...
It is an intensive activity in which the onus is on the students...
The students will organise themselves, learn how to capture a clip and use Tracker...and ask the mentor for help if they need it...
In the stand-alone two hour version, this would be what they did, the estimate of g and why it is what it is...in the four-part version the presentation would include next steps

In the stand-alone two hour workshop, the presentation would be what they did, the estimate for g, and why it may be different from the theoretical value. In the four-workshop version, the presentation would include next steps.

We conclude the workshop with a return to our tennis player and footballer with a discussion and appreciation of the beauty of movement...

Mum:
Amazing how sport goes into computer and covers science and technology. Seb (mentor) was very good at helping Jake
Mentor Hannah 15:
I like PE and ICT so it was good putting the two together. I was very interested!! Software is easy to use!!☺

Student Thomas 13:

Eye opening. Not what I was expecting. Going to get it. Tracker easy to use.
Great software, good to explore it more and we will be having a go at home. Thank you.
Student Jake 15:
I enjoyed using the software and learning about how many forces get upon something so simple. Love this.
Student Jake 10:

Clever how you can connect computers to cameras and analyses the footage
Mentor Seb 15:

It was very interesting for people to learn it quickly and I think I learnt a lot too
We normally take 2-hours to explore movement, taking and analysing video clips using Tracker software.

This time we taught eight 15-year olds how to do it - and then asked them to mentor younger pupils...and their parents...in 50 minutes.
