I will be starting my IB Extended Essay soon and desperately need help choosing a topic. I have taken Physics as my subject because I really enjoy it. I am trying to combine physics with a sport because it will be more interesting for me. I had brainstormed a little, and found that golf and football(soccer) sounded very interesting. I thought about the equipment used in each sport, like the golf ball, clubs, the football, the football shoes etc. I could probably do an experiment on the effect of the surface of the golf ball or the movement of the football through the air, but these topics didn't sound very easy to perform. I also thought about the football kick, and how kicking the football from different parts affects the movement of the ball, the power and speed of the kick could also be useful factors, but it will be very difficult to keep things constant. Does anyone have a good idea for a physics extended essay? If you think physics in sports is a good start can you please help me pick a topic and help me decide ways in which i could experiment on the topics. Thank you for your time and help!
