During the next six weeks, these scientists will be studying, manipulating, and understanding the science behind sports.
On our first session we talked about how understanding the science behind sports can actually improve our game and make us better athletes. We then looked at basketball in particular and what dribbling is all about. To understand what is happening and how energy is transferred between the ball and the surface it is bounced off, we performed an experiment in which the scientists had to bounce the b-ball off three different types of surfaces. Each time, the height of the ball was measured in centimeters to see how much energy "stayed" on the ball with each bounce. To help us take more accurate measurements we recorded each trial and used painter's tape to make 20cm markings on the wall/meter stick. The three surfaces used were carpet, wood, and cement.
After collecting our data and making observations we talked about our findings. Scientists noticed how more energy seemed to stay on the basketball on the harder surfaces, especially concrete. This was noticed on how many centimeters the ball bounced back up after being originally dropped off from 100cm off the ground. We then talked about what surface is actually used to play basketball - wood, and why is it not played on concrete being that the best return bounce seems to be off concrete. Some conclusions that these scientists came up with is that maybe we don't want the ball to keep too much energy because then it would be harder to control the ball as you dribble down the court. We concluded by talking about the force of gravity and how that is the force that drives all objects, including us humans to stay put on the Earth.
Pssst, they don't know they are becoming physicists ; )
