## Launch Angle Vs. Time of Flight

**Summary:**An essay that explains a physics experiment of how to find out how launch angle of an object affects time of flight.

To find out how launch angle affects range and time of flight, an experiment must be conducted. Some of the instruments needed to perform this experiment is a timer, 5 meter sticks, and a marble launching machine that has an angle adjuster. To conduct the task, set the marble machine at a 90 degree angle and shoot it and time from when the marble leave the machine to when it hits the muzzle again. The trajectory should a vertical line with no range. The times recorded for the 90 degree angle were 1.52 sec, 1.52 sec, and 1.49 sec; these three numbers averaged together equals. This first measure of times can be used to find the initial velocity of the marble. To find this, the equation Vf-at=Vi can be used. When the numbers are substituted in, the initial velocity equals 7.40655 m/s. Then measure the time marble is in the air and how...
