I’m looking at how we can reduce pressure drag with different position and using different types of helmets and also reduce the skin friction drag by using different skinsuits.
Topic: Cycling aerodynamics
Our collection of resources on cycling aerodynamics is a great opportunity to look at forces and speed in relation to cycling and think about how these might be measured and how one affects the other.

Topic: Sporting edge
Muscles can only contract and then relax – they can never push. So for every body movement there are muscles that contract to make the bones move and others that contract to pull the bones back to their original position.
Measuring the power output of elite athletes – Activity
In these videos, teacher Sinead Senek, explains how her students learned about forces through hands-on experiences and Hub resources.
