Part 1 Directions: Before each trial, click the button, set values, and click to make the man
move. Then DRAW the resulting Position, Velocity and Acceleration graphs.
What do you notice about the slopes of the Position graphs as the velocity is increased?
As the velocity increased, the slope of the Position graph increased.
What do you notice about the Velocity graphs as the velocity is increased?
The velocity graphs remained horizontal, but started at higher, more positive values.
What do you notice about the Acceleration graphs?
The acceleration graphs were always zero.
1. Set velocity to 0.50m/s
3. Set velocity to 2.00m/s
2. Set velocity to 1.00m/s
4. Set velocity to 3.00m/s
5. Set velocity to 4.00m/s
6. Set velocity to 10.00m/s

A. Go to https://phet.colorado.edu/en/simulation/legacy/moving-man B. Select “Charts.” C. Move all sliders and watch what happens to the graphs. D. Answer the questions at the bottom of each page in complete sentences. Part 1 Directions : Before each trial, click the button, set values, and click to make the man move. Then DRAW the resulting Position, Velocity and Acceleration graphs.

What do you notice about the slopes of the Position graphs as the velocity is increased? As the velocity increased, the slope of the Position graph increased. What do you notice about the Velocity graphs as the velocity is increased? The velocity graphs remained horizontal, but started at higher, more positive values. What do you notice about the Acceleration graphs? The acceleration graphs were always zero.

  1. Set velocity to 0.50m/s
    1. Set velocity to 2.00m/s
      1. Set velocity to 1.00m/s
      2. Set velocity to 3.00m/s
    2. Set velocity to 4.00m/s 6. Set velocity to 10.00m/s

Part 2 Directions : Change the sliders to the given values. Draw the resulting graphs.

What happens to each of the shape of the position graphs when the acceleration is not 0? The position graphs are curved. What do you notice about the shape of the velocity graph when acceleration is not 0? The velocity graphs are straight lines with either a positive or negative slope. What does the negative sign do to the graphs for: Position? A negative position starts the man to the left of 0, closer to the tree.

Velocity? A negative velocity moves the man to the left rather than the right.

Acceleration? A negative acceleration means slowing if moving in the positive direction and speeding up if moving in the negative direction.

  1. Set acceleration to 0.50m/s^2 8. Set position to 2.00m
    1. Set acceleration to -0.50m/s^2 10. Set position to 4.00m
  2. Set acceleration to 2.00m/s^2 12. Set velocity to -2.00m/s
