Part I: Virtual Lab Option

The simulator that you will use to design your experiment is used for projectile motion. We are only concerned with being able to drop an object in a way that will allow you to obtain accurate data.

Materials: Projectiles simulation virtual lab. Lab will open in a new window.

The simulator that you will use to design your experiment is used for projectile motion. We are only concerned with being able to drop an object in a way that will allow you to obtain accurate data.

Procedure:

Run the simulation and select the Intro tab. You will see several controls that are not important for this activity. Beneath the cannon, you will see a slider for initial speed. Please slide that down to 0 m/s. Select the cannon and drag it upwards. You will be selecting three different heights to drop the object from.
Drag the cannon up to the first elevation that you would like to use. Record that height on your lab worksheet. Press the red "fire" button at the bottom. A line of dots appear below the cannon as your object falls to the ground.
Across the top of the simulator, there are measuring devices. Select the Time/Range/Height device on the left. Drag it down to the very bottom dot where the object you dropped hit the ground. The center of the cross should be over the point to get a reading.
Record the time from the measuring tool on your lab worksheet. Repeat this process two more times at different heights of at least 10 meters.
Using the data, determine the acceleration due to gravitational force. Be sure to show your work for all calculations.

	Distance (meters)	Time (seconds)	Acceleration due to Gravity (m/s²) (show your work in part b, below)
Trial 1
Trial 2
Trial 3

Your calculations for acceleration due to gravitational force (Hint :Remember, d=v_ot+ 1/2at² is the equation for the distance an accelerating object travels. How could you simplify that equation if you are starting from rest?). Make sure to show your work below.
