aaHomework

2nd June Hello again The task for this topic is too investigate speed and forces related to motion, the technology involved in this over the last century and how it has changed in either a. a chosen sport that is related to forces and motion b. car racing

You will need to look at statistics of speed and performance over the last 50 years, look at how the sport or cars etc have changed to reduce friction, aspects of the equipment that increase friction ( eg for grip), specialised equipment, materials or surfaces used to increase speed, shape or body position to maximise speed and physical conditioning of the athlete or driver to maximise speed and endurance.

OR if you don't want to do this you can c. a comparison in animal groups by finding the fastest animals compared to the slowest and then focusing in on one particular group eg the cat family looking at the speed of different members of the family and specific adaptations and energy requirements needed for this. You also need to relate the speed aspect of your chosen animal group to its specific role in its community (ecological niche)

Please present this as a powerpoint or prezi and paste the link on the wiki tchmscience or email me at chamilton@tawacollege.school.nz by Thursday 31st June
