Summary for the Fastest Ball Challenge.

Firstly, when we were guided into the Physics Lab, we were received with warm welcomes from Professor Sum and the facilitators. He explained to us further that the focus of the challenge was to find the difference between using a stopwatch and photogates to measure the time taken for the ball to travel a different distance, and see how different the methods used to measure is.
Another focus of this project, the main focus, is to find the length of the inclined plane where we released the ball, along with the angle of inclination. The objectives for this project is to find out how does the angle of inclination and the length of the inclined plane where we released the ball differs the speed, as, there is a competition for us to find the length of the inclined plane and the angle of inclination where the speed for the ball to travel is the fastest. Therefore, the competition and the prize also motivates us to work even harder.
Once we were at our workbench, we immediately started to differ the angles of inclination and started to time the time taken for the ball to travel the horizontal distance using the stopwatch. Then, we also started to change the length of the inclined plane where we released the ball, and released that the longer the inclined distance it is from the horizontal distance, the ball will travel faster. Then, after the teabreak, we had oil and we applied oil onto the ball, and its tracks. We started to measure the angle of inclination and the length of the inclined plane where we released the ball for the "oil" ball. Afterwards, we had a competition where every group had 3 times to drop the ball from the angle of inclination and the length of the inclined plane were we dropped the ball from. The group which had the ball which took the least time to travel the same distance will be the one who wins.
