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

S. No.

Time of Flight

Maximum Height Attained

5.

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.

Table 2: Experiment 2 - Range at 45°

S. No.

Initial Velocity

Horizontal Velocity

Vertical Velocity

Range at 45°

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.
