Other (Not Listed) Instructions:

Select a step or stage in a Rube Goldberg device. You will examine that step in relation to the previous and subsequent steps, analyzing the behavior of the object in the selected step. In addition, you will perform energy, velocity, and force calculations. Finally, you will discuss the analytical tools that could be used to confirm your velocity calculations and their relationship to the electromagnetic spectrum.
I. Step Selection: Select a step or stage in the Rube Goldberg device. Provide a concise description of the step.
II. Previous Step
A. Description: Analyze the behavior of the object in the interaction between the previous step and the selected step, qualitatively describing the transfer of energy that occurs. Which principles of conservation of energy and momentum can you apply to this behavior?
B. Equations: Provide the equations that can be used to describe the transfer of energy and the momentum of the object from the previous step to the selected step. What is the connection between the basic physics concepts in the equations and the interaction of the object and force(s) from step to step?
C. Calculations: Using the applicable equations you identified, calculate the transfer of energy and the momentum from the previous step to the selected step. How do these calculations help you predict the object’s location and velocity from the previous step to the step you selected?
III. Selected Step
A. Initial Velocity: Calculate the initial velocity of the object in the selected step. What does the initial velocity of the object tell you about the behavior of the object?
B. Equations: Provide the equations that can be used to describe the change in type and amount of energy, if applicable, across the selected step.
C. Energy Calculation: Calculate the amount of energy that is converted from one form to another form using the changes in mass and height. For example, if appropriate for your selected step, you could calculate the transformation of potential energy to kinetic energy.
D. Velocity and Force Calculations: Calculate the change in velocity that would be observed based on the changes in type of energy. Then, use Newton’s second law to calculate the force acting on the object.
IV. Subsequent Step
A. Description: Analyze the behavior of the object in the interaction between the selected step and the subsequent step, qualitatively describing the transfer of energy that occurs. Which principles of conservation of energy and momentum can you apply to this behavior?
B. Equations: Provide the equations that can be used to describe the transfer of energy and the momentum of the object. What is the connection between the basic physics concepts in the equations and the interaction of the object and force(s) from step to step?
C. Calculations: Using the applicable equations you identified, calculate the transfer of energy and the momentum from your selected step to the subsequent step. How do these calculations help you predict the object’s location and velocity from the step you selected to the subsequent step?
V. Electromagnetic Spectrum
A. Tool: Select an analytical tool that uses electromagnetic waves to measure velocity. Explain how this tool uses electromagnetic waves to
measure velocity. Examples of tools you could consider are LIDAR and RADAR.
B. Properties: Describe the region of the electromagnetic spectrum that the tool you selected uses. What properties distinguish this region of the spectrum from other regions?
C. Configuration: Describe how you would configure your selected tool to measure the velocity of the object as it moves from step to step. Ensure that your description of the tool configuration is complete and realistic. For example, in your description of the configuration, you could consider things like the placement of the tool and the number of measurements you would take.

* Step Selection:
In the selection phase, a spring hits 1.78kgs of steel ball, causing an inelastic collision. The hit ball then rolls down a board inclined at 45 degrees, measuring two meters in length.
* Previous Step:
* Description:
The potential difference of a spring-loaded with a force of 10N is compressed until it is released. The potential energy is converted into kinetic energy once the spring is released as it travels towards the stationary ball (Shapiro & De Berredo-Peixoto, 2013). The released spring generates an inelastic collision with the stationary, which, in effect, transfers the kinetic energy to the ball.
* Equations:
The compressed spring accelerates at a velocity of 2.4 m/s after release. It was compressed to approximately 0.62 meters. It takes around 0.22 seconds to recoil and hit the steel ball. The spring reverts' final velocity to 0.0m/s after hitting the ball because there is no external force to cause it to recoil.
The velocity of the spring is equal to:
Final velocity = Vi + at
= 0 m/s + (2.04m/s^2 * .22)
= 0.4488 m/s
* Calculations:
Calculation of the spring's energy transfer
The Potential Energy (P.E) of the spring = ½ k x^2
= ½ (0.0059) (.62m) ^2
= .0011 joules
Therefore, the compressed spring has a potential energy of 0.0011J. The kinetic energy, denoted (k), is the value of energy that the spring hits the ball with at a distance (0.62m). Hence, the amount of energy the spring loses as it transitions from potential to kinetic then to potential energy is calculated by subtracting P.E- K.E (Shapiro & De Berredo-Peixoto, 2013).
* Selected Step
* Initial Velocity:
The uncoiling spring hits the steel ball with a 10N force. The algodoo graph shows that the spring hits the ball, causing its initial speed to increase from 0.081 m/s to 1.320 m/s within 0.22 seconds. The speed increases to 5.4 m/s as the ball rolls down the inclined board in 1.7 seconds (Shapiro & De Berredo-Peixoto, 2013). Therefore, the balls accelerate at a velocity of 3.129 m/s^2. However, the speed r...
