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.
