GCSE PE- Levers and Mechanical Advantage

Rich from Planet PE explains the concept of levers, a topic often found challenging by students. He describes the three types of levers—first, second, and third class—highlighting their components: fulcrum, load, and effort. Rich discusses how these levers function in the human body, using examples like the neck joint, elbow, and ankle. He also explains mechanical advantage and disadvantage, emphasizing how these principles apply to sports and movement. The video concludes with a call to action for viewers to subscribe and engage with the channel.
