# Physics: Projectile Motion Experiment

**Projectile Motion Experiment**

** **

By **Monday, August 19,** perform the following experiments online at the Projectile Motion – Galileo website. (http://galileo.phys.virginia.edu/classes/109N/more_stuff/Applets/ProjectileMotion/jarapplet.html)

Fill in the tables, and post your answers to the questions.

**Question 1**

**Procedure:** Keep the initial velocity fixed at 50 m/s. Perform the experiment for each of the following angles:

- 15 degrees
- 30 degrees
- 45 degrees
- 60 degrees
- 75 degrees

**Record in table 1:**

- The maximum horizontal distance (Range) traveled by the projectile at various angles
- The total time of flight at various angles
- The maximum height attained

**Table 1: Experiment 1 – Range & Time of flight**

** **

**Observe and Analyze:**

- What angle produces the maximum range? Why?
- What angle produces the maximum height? Why?
- Are there angles which produce the same range? If so, how would you explain this?

** **

**Question 2 **

**Procedure:** Set the angle to 45 degrees. Perform the experiment with the following initial velocities.

- 30 m/s
- 40 m/s
- 50 m/s
- 60 m/s

**Record in Table 2: **The horizontal and vertical components of the velocity and the ranges for each of the velocities.

**Observe and Analyze:**

- As the velocity is increased what happens to the Range?
- Using the initial horizontal and vertical velocities from your table, verify mathematically that the range is correct for the initial speed of 60 m/s.
