Moving Motion Simulation Part 3
Use the "Moving man" simulation to answer the following questions. To open up the simulation please click here
- 1.
Step one: Click on the tab "chart" set the position to zero the velocity to 5 m/s and velocity to -2 m/s/s Predict what the position graph will look like
- 2.
Predict what the velocity graph will look like
- 3.
Predict what acceleration graph look like.
- 4.
Press play and pause when the moving man returns to his starting point. Where you predictions correct? Why does the graphs appear the way they do?
- 5.
Step one: Make sure that all of moving mans values are set to zero and that the tab is set on "introduction". Step two: Set the moving mans velocity to 5 m/s and the acceleration to -2 m/s/s Step three: Press play then press pause when the moving man returns to its starting point. Question: Which of the following best describe how blue slider (position) moved
- A.
It moved to right at a constant pace
- B.
It moved to left at a constant pace
- C.
It moved to the right then turned around and moved to the left
- D.
It moved to the left then turned around and moved to the right
- E.
It remained stationary
Correct Answer
C. It moved to the right then turned around and moved to the leftExplanation
The given information states that the moving man's velocity is positive (5 m/s) and the acceleration is negative (-2 m/s/s). This indicates that the moving man initially moves to the right (positive direction) with a constant pace (velocity) due to the positive velocity. However, the negative acceleration causes the moving man to slow down and eventually turn around. As a result, the moving man changes direction and moves to the left (negative direction). Hence, the correct answer is "It moved to the right then turned around and moved to the left."Rate this question:

The blue slider (position) remained a positive value for the entire time
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The blue slider (position) remained a positive value for the entire time. This means that the position of the blue slider was always greater than zero throughout the given time period.Rate this question:

Which of the following best describes the motion of red slider (velocity).
- A.
It remains stationary
- B.
It moves to the left
- C.
It moves to the right
- D.
It moves to the left then to the right
Correct Answer
B. It moves to the leftExplanation
The correct answer is "It moves to the left". This can be inferred from the fact that the motion of the red slider is described as moving to the left, indicating a unidirectional movement in that direction.Rate this question:

The red slider (velocity) remains positive the entire time.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the question states that the red slider's velocity remains positive the entire time. However, it is possible for the velocity to change and become negative at some point, which contradicts the statement. Therefore, the correct answer is false.Rate this question:

- 9.
At what point does the slider turns from positive to negative.
- A.
When the moving starts
- B.
When the moving man is paused
- C.
When the moving man reaches the apex of his move (maximum distance from the starting point)
- D.
It never turns negative
Correct Answer
C. When the moving man reaches the apex of his move (maximum distance from the starting point)Explanation
When the moving man reaches the apex of his move (maximum distance from the starting point), the slider turns from positive to negative. This is because at the apex, the moving man changes direction and starts moving back towards the starting point, which is in the opposite direction. Therefore, the slider changes from positive (representing movement away from the starting point) to negative (representing movement towards the starting point).Rate this question:

The reason the red slider (velocity) turns from positive to negative is because the moving man changed direction, he quit moving to the right and started moving to the left.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The red slider (velocity) turning from positive to negative indicates a change in direction. This suggests that the moving man stopped moving to the right and started moving to the left. Therefore, the statement "The reason the red slider (velocity) turns from positive to negative is because the moving man changed direction, he quit moving to the right and started moving to the left" is true.Rate this question:

How does the green slider (acceleration) behave?
- A.
It moved to the left
- B.
It moves to the right
- C.
It moves to the right then to the left
- D.
It remains stationary
Correct Answer
D. It remains stationaryExplanation
The green slider (acceleration) remains stationary. This means that it does not move or change position.Rate this question:
