Introduction:
Focus variable are range & angel
Methods:
· Here we used Stopwatch to record time, meter to record distance, and Level app to measure the angle.
· We did a rocket launch experience with 3 types of tasks that include Varying Stomp Force to measure time, Varying Launch Angles to measure time, and Competition to measure horizontal distance. After assembling the rocket and used the Measure app on iPhone to set up the angle, I prepared the stopwatch to measure the time while launching the rocket.
· For the first task we had to stick with one angle to while experiencing the stomp force.
· I stepped on the launch pad lightly, medium, and hard with 3 different trials while my friend was holding the base of the rocket to measure when the rocket hit the ground. After taking the time data recorded on the stopwatch for the task, we had to calculate the Average time needed to solve problems set.
· Task 2 was about measuring time with different angles at 25, 45, and 65 degrees for three trials with hard force. First step was setting up the launch base with the app level at the written angles, and then fire the rocket while measuring time at landing.
· Task 3 was a competition between 3 other groups to measure the horizontal distance with similar hard force applied. We started to launch once per group to measure the furthest distance among us.
· For task 1 and 2 calculations, we have to find the initial Horizontal/Vertical velocity, resultant velocity, predicted peak height, flight time, and range.
