NAME: CLASS PEROID: Applied Physics Lab Worksheet Observation 1: Law of Motion Your first task is to review each Law of Motion before beginning your observations. Now, go outside for 15 minutes and observe one object in motion. Study that object and its behavior. Apply your observation to one of the 3 laws from Newton’s Laws of Motion and record the following data. 1. List the object you observed: 2. Describe what motion was observed: 3. List which Law of Motion applies to your observations and why: Observation 2: Speed Find an area where you can observe a person walking on the sidewalk. Each seam of concrete is approximately 3ft in length. Use this length for a measurement and use a cellphone or stopwatch to assist with your calculations for obtaining data based on a person’s speed. 1. List the formula for calculating speed: 2. Document your data calculations, with the designated values in the formula for speed: 3. Show your work and label your measurement of speed using units from the English system: Observation 3: Power Can you estimate the power you generate as you climb stairs? Move your weight through a distance and calculate the rate at which you do this work. Be sure to take proper measurements and record your data accurately. 1. List the formula for calculating power: 2. Document your data calculations, with the designated values in the formula for power: 3. Show your work and label the rate of power in units from the English system: Observation 4: Energy Review the definitions of Energy & Work. Now, find an object, any object. 1. List the object you observed and the setting it is in: 2. Which Form of Energy does your object categorized as: 3. What type of Energy does this object possess that allows it to preform Work? Observation 5: Energy Being efficient with our energy is an important part of respecting and appreciating our abundant resources. Observe an example of wasted energy. 1. List your observation of wasted energy: 2. What you would recommend in order to utilize this resource more responsibly? Observation 6: Heat and Temperature Find two objects in close proximity to one another. Touch both of these objects at the same time. Use the table below to record your data of both objects. Describe the basic perception of temperature for each. (ex. Hot, Warm, Cool, Freezing, etc.) Indicate the source of how the heat flow transfer of energy is taking place. Object A Object B List the object 2. Perceived Temperature Heat Flow Observation 7: Temperature Find a Thermostat in a building or residence. 1. Record the location or name of the building: 2. Record the temperature in Fahrenheit: 3. Now record the same temperature using the Celsius Scale: Observation 8: Wave Motions and Sound Read through activity 8 in full before beginning your observations. Find a location outside where you can sit and observe both humans and nature. Set a timer for 2 minutes. Using your ears only as the tool for observation, close your eyes or place and begin to notice your surroundings. After the time has expired, record the following data: 1. List as many sounds made from humans that you noticed: 2. Now describe 2 of the human made sounds in more detail, such as description of the pattern, direction, quality or type the sound, etc.: 3. How did these sounds make you feel? Now, repeat the same steps in the instructions, however, listen to only the sounds made from Nature. After 2 minutes of observing the sounds of nature record your data from observations: 4. List as many sounds made from nature that you noticed: 5. Now describe 2 of the natural sounds in more detail, such as description of the pattern, direction, quality or type the sound, etc.: 6. How did these sounds make you feel? Sound Tips: It is best to close your eyes during the 2-minute period, so your sense of hearing becomes more activated. Sounds made by Nature tend to be easily heard in the morning or at dusk. Observation 9: Electricity Ch 6 explains the movement of electrical energy that can be utilized for powering devices. Search for a Battery and record the following data: 1. Indicate the voltage of the battery: 2. Tell me what this battery is used for: 3. What energy form conversion is being converted into electrical energy: 4. Does this battery rely on Alternating Current or Direct Current for power? 5. Draw (or trace) the battery using a pencil or pen in the space below: Observation 10: Light Indiana’s state insect is the Say’s Firefly, which relies on bioluminescence for survival. Our textbook discusses the phenomena of Bioluminous light as a Case Study on page 180 (may need to confirm page number). First, Read the case study. Secondly, watch this video. Lastly, answer the questions below. Video: See link or search TED Talks. The brilliance of bioluminescence – by Leslie Kenna https://www.youtube.com/watch?v=oKjFVBVGad0 Now, answer the following questions: 1. If you had a bioluminescent superpower, what would it be and why? 2. What part of your body or which organ would you illuminate, and why? 3. What color would your illumination be?
