Summary

The learner should be able to solve, using experimental and theoretical approaches, multi-concept, rich-content problems involving measurement, vectors, motion in 1D and 2D, Newton’s Laws of Motion, Work, Energy, Center of Mass, Momentum, impulse, and collisions....

Description

Projectile Motion Virtual Laboratory Without laboratories, men of science are soldiers without arms. - Louis Pasteur In this part of the module, you will explore the Projectile Simulator Interactive to determine the factors affecting the motion of a projectile. Learning Objectives: 1. To observe the motion of a projectile. 2. To determine the factors affecting projectile motion. Materials:

Simulation Title: Projectile Motion https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html

Procedure: 1. Once the program is loaded, select the intro option and familiarize yourself with the simulation components.

2. Under the “Velocity Vectors” and “Acceleration Vectors,” check the “Components” checkbox, then uncheck the “Air Friction” to disable air friction in the simulation .

Part A-1. Horizontally Launched Projectile with the same Height and initial horizontal velocity. 3. Select an object of your desire from the given list in the simulator. 4. Position/Drag the cannon to your preferred Height. By dragging the speed glider, adjust your preferred initial velocity. Record the data. 5. Measure the time of flight by dragging the timer where the projectile hits the ground and measure the range by positioning the tape meter below the canon, then drag the meter horizontally to where the object falls. Observe and record the data in the data table. 6. Repeat by selecting two more objects of your desire and using the same conditions. 7. Using the guide questions, explore the Projectile Simulator Interactive. Table1: Effect of Mass on the Motion of a Projectile Height of the Canon: _____m Object Mass (kg)

Initial Velocity: ________ m/s Time of Flight (s) Range (m)

1. Does the mass of an object affect the motion of a projectile? Justify your answer. Answer to Guide Question 1:

Part A-2. Horizontally Launched Projectile at same heights with different initial horizontal velocity. 8. Repeat procedures 1 to 5. 9. By keeping your desired Height constant, vary the initial velocity for each trial. Then, observe and record the data. Table2: Effect of Horiontal Velocity on the Motion of a Projectile at Constant Height

Height of the Canon: _____m Trial Initial Velocity (m/s) 1 2 3

Time of Flight (s)

Range (m)

2. How does the initial velocity affect the time of flight and range of a projectile? Answer to Guide Question 2:

Part A-3. Horizontally Launched Projectile at different heights with the same initial horizontal velocity. 10. Repeat procedures 1 to 5. 11. By keeping your desired initial velocity constant, vary the launch height for each trial. Then, observe and record the data.

3. How does the launch height affect the time of flight and range of a projectile? Answer to Guide Question 3:

Part B-1. Vertically Launched Projectile at a constant angle with different initial velocities. 12. Repeat procedures 1 to 3 and 5 13. Position the canon zero meter from the ground. 14. Set the canon at a certain angle (less than 90 degrees). Record your data. 15. By keeping your desired angle constant, vary the launch speed for each trial. Then, observe and record the data. Table4: Effect of Initial Velocity on the Motion of a Projectile at Constant Angle Launch Angle: _______ Trial 1 2 3
