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

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.
