PhET Simulation - Projectile Motion

Learning Goal 1: Predict how varying initial conditions effect a projectile path (mass, angles ,initial speed, and , initial height)
Learning Goal 2: Use reasoning to explain the predictions.
Learning Goal 3: Explain common projectile motion terms in their own words. (launch angle, initial speed, initial height, range, final height, time)
Learning Goal 4: Describe why using the simulation is a good method for studying projectiles.

Each part asks you to collect data to determine the effect of the different parameters on the time and distance. You will change the objects mass, angle, and the velocity at t= 0.
You will need to use time/distance meter, the green dot marks Ymax, the yellow dot marks Xmax

Use the reset bottom to clear the data from the screen
Adjust the different parameters and fill out the tables below. Use your data to answer the following questions.

Part A: Change only the object (mass) and leave all other parameters alone. Use the blue meter to get data

Part B: Pick the human and set an angle of 70o and set cannon height at 1m. Change only the initial speed.
• How does changing the initial speed affect the projectile motion of an object?

Part B: Pick the piano with an angle of 60o and speed of 15m/s and change only the cannon height
• How does changing height of Y0 affect the projectile motion of an object?

Part D: Set the cannon height to 1m and pick the golf ball as your object. Change only the firing angle.

• How does changing the firing angle affect the projectile motion of an object?

Part E: By experimentation determine the angle that produces the max Y value (height)? What angle produces the max X value (range)? Change only the firing angle.
Xmax angle = _________ Ymax angle = _______________
Part F: Analysis of data
a. List the factors that affect the landing site of a projectile and the discoveries you made manipulating the simulation.

b. For each item, briefly explain why you think the landing location was altered.

c. Which factor(s) appear most important in projectile motion? Explain your answer!

Everyday Physics in your life: Dollar store toys
d. If we went outside to tennis courts again, what would you do to achieve the greatest range for your projectile bug?
