Motion with Moving Man SIM Representations of Motion
For this homework assignment, you will need to use the Moving Man Exploration available here: . As you work through these problems focus on making sense of the motion graphs and discuss your reasoning with your peers!
What is the graph really telling you about the motion? Graphs are used in science and many other areas (!) to record and convey a whole lot of information, just like a photo of the foothills conveys a whole lot of information about the area we live in. They provide a compact way to tell the
whole history
of an object's motion. 1)
(0.5 pts) First, orient yourself to the Moving Man tool by selecting the “accelerate” motion from the choose motion list. With the moving man starting at a position of -8 m, set him to “accelerate” at 1 m/s
2
from an initial velocity of 0. Observe the motion. Also notice that the tool comes equipped with a playback
feature and a double-bar cursor that you may move with the mouse
to probe position, velocity, and acceleration along the graph. What is his velocity when he crosses the origin (the position of 0 meters)? 4 m/s
2)
(0.5 pts) Below is a graph of a balls motion. Use the Moving Man Applet to reproduce the shape of this graph. Which of the following sentences gives the best interpretation of the ball’s motion? The ball moves along a flat surface. Then it moves forward down a hill, and then finally stops. The ball doesn't move at first. Then it moves forward down a hill and finally stops. The ball is moving at constant velocity. Then it slows down and stops. The ball doesn't move at first. Then it moves backwards and then finally stops. The ball moves along a flat area, moves backwards down a hill, and then it keeps moving. Not answered 3)
(1 pt) Use Moving Man to simulate the following scenario: A man starts at the origin, walks towards the tree slowly and steadily for 6 seconds, then stands still for 6 seconds,
and then turns around and walks towards the house steadily about twice as fast for 6 seconds. a)
Which of the following velocity versus time
graphs conveys this type of motion: A B
C D E F G H .........
Not answered b)
Which of the following position versus time
graphs also conveys this motion? A B C D E F G H ..........
Not answered
4)
(4.5 pts total) A car is traveling along a road. Its velocity is recorded as a function of time and is shown in the graph below.
Use the Moving Man Simulation to reproduce the shape of this graph. You’ll find that there are a variety of approaches for recreating this type of motion within the applet, these include among others: • reproducing the motion using the walk motion and the velocity slider control, • reproducing the motion using the accelerate motion and acceleration slider control, or • reproducing the motion using direct mouse control over the walking man. Note: This method is hard! a)
(1 pt) Describe in your own words the motion of the car and give a everyday life scenario in which the car’s velocity would resemble the plot shown above. Explain your reasoning by relating your description to what you see in the graph of the velocity vs time. This is a velocity vs time graph, and the graph records the velocity as time passes. The magnitude of the velocity tells us the speed of the car and as well the direction the car is traveling. The graph shows a constant velocity of 15 m/s for 3 seconds, over
the next 5 seconds the velocity decreases to 0. And then slowly the car begins to increase to 20 m/s. b)
(0.5 pts) From this graph, what do you know about the position of the car at time equals 0 seconds? There was no information of the position of the car. We just know the car is going
in a positive position. So at 0 we don’t really know where the car position is at it could be either or.
c)
(0.5 pts) How far does the car travel between 0 and 3 seconds? 45m

intos Learning Activities
Last time, you have learned how to determine if an object is moving or not.
For this module, you will learn how motion can be visualized or illustrated using
tape charts and motion graphs. To help you get ready, perform the task
below:
by 1
Read and analyze the following
statements and get ready to answer
the questions listed below:
A jeepney is moving at a rate of 45
kilometers within 0.50 hour before it
stops at a red light. After 5 minutes
the vehicle moves again, but this
time it initially moves at a rate of 15
kilometers for 15 minutes which then
increased to 35 kilometers after
another 15 minutes. The jeepney
then continued to move at the
same speed until it reaches another
stop.

Purpose
Mathematical models based on quadratic equations describe curved paths through space.
The purpose of this project is to develop an understanding of techniques used to apply quadratic models to describe motion.
Assignment Goal
Describe the motion of a rocket using a quadratic model.
Instructions:
Respond to each of the questions. Your solutions must document all of your work.Scenario: A toy rocket is launched straight upward from a pad 10 ft above ground level with an initial velocity of 80 ft/sec. Use the general formula for the vertical position (height) of an object moving under the influence of gravity ?= ―12??2 + ?0?+ ?0 where s0 is initial vertical position, v0 is initial velocity, and s is vertical position of the object.
1. Define a model (equation) to express the vertical position (height) of the rocket s (in meters) above ground level t seconds after launch. Let g = 32 ft/sec2.
2. Graph your equation with time on the horizontal axis and height on the vertical…

Please helpppp explain I’m confusedddddd
For each graph below, try to describe what type of motion (imagine yourself walk- ing along a path in front of a motion detector) would produce such a graph. Con- sider the horizontal axis to represent increments of time and the vertical axis to represent increments of distance from a frame of reference. Then write a detailed description of how you produced the graph. The description should be detailed enough that another group could follow your directions to reproduce the graph and should include such vocabulary as faster or slower rate, increasing function values, decreasing function values, and the function is constant on defined intervals
Warning! Some of these graphs may not be functions, and thus do not make sense in a physical way related to motion.

1. Dynamics is concerned with describing the movements of objects.
2. The kinematic equations of motion are valid for objects with constant acceleration only.
3. A body moving with constant acceleration has its speed changing by a fixed amount.
4.
An object moving in the +x direction experiences an acceleration of +2.0 m/s?. This means the object travels 2.0 m in
every second.
