Lab #4: Projectile Motion

Data Table
Conclusion:
In average, we got an initial speed of 116.32 cm/sec while hypothetically it is supposed to be around 35 cm/sec. some possible sources of error are air resistance, the angle, and inaccurate measurement. In real life, there is air resistance, but it was not taken into consideration in our calculations. Another source of error is the angel from which we shot; we tried to shoot with a zero degree angle, but it could have been greater than zero degree in some of the trials.

Reflection:
By doing this project, I learned how to calculate the initial velocity without having the time. I also learned that the actual result can vary from the hypothetical measurement, so other factors such as air resistance should be considered. This lab helped me in comprehending projectile motions.
