Unit 4: Vertical Motion Lab

Last updated almost 3 years ago
21 questions
Follow this link to open the phet simulation that will be used in this lab.
https://phet.colorado.edu/sims/html/projectile-motion/latest/projectile-motion_en.html

once opened, click on the icon labeled "intro"
Make your settings like the image.

1. Lower the height of the launcher to 0m

2. Change the initial speed to 10m/s on the slider

3. Check the components box for both the velocity vectors and acceleration vectors section.
The question we are investigating today is: How do mass and initial velocity affect the height and time of a projectile?


Lab instructions: Change the Mass and Initial Speed to match the table (provided as a link in question 2). Use the Blue Measuring tool from the simulation to take measurements
3

Hypothesis: Write a testable answer to the above question in if/then format.

7

Data table:

Add your completed data table.

1

What happens to the height as the initial speed increases.

1

What happens to the height as the mass increases.

2

Explain why the height changed or did not change due to manipulating the objects mass or initial velocity.

1

Compare the time needed to reach max height and the total time for each launch. What is true.

1

Launch one more time and watch the vectors. What happens to the Velocity Vector (Green arrow) throughout the launch?

1

Launch on more time and watch the vectors. What happens to the Acceleration Vector (Yellow arrow) throughout the launch?

1

Where on the path is the projectile the fastest?

1

Is there a part on the path when velocity = 0m/s?

2

Is there a part on the path when acceleration = 0m/s2?

1

Does gravity affect the projectile when it is rising?

1

How does gravity affect the projectile when it is rising?

1

Does gravity affect the projectile when it is falling?

1

How does gravity affect the projectile when it is falling?

2

A pumpkin is launched directly up and reaches a height of 10 m. How long would it take for the pumpkin to go up and down? (Hint, use the time equation)

2

A pumpkin is launched directly up and reaches a height of 10 m. How long would it take for the pumpkin to rise?

2

A pumpkin is launched directly up and reaches a height of 10 m. How long would it take for the pumpkin to fall?

2

A pumpkin is launched directly up and reaches a height of 10 m. What is the velocity just before the pumpkin hits the ground? (Hint, use the time in the previous question)

2

A pumpkin is launched directly up and reaches a height of 10 m. What is the velocity as the pumpkin is launched?

5

A pumpkin is launched directly up and reaches a height of 10 m. Using your previous answers, draw the scenario with labeled initial velocity, velocity at the top, final velocity, time to rise, and time to fall.
