Identify the area of physics that is most relevant to each of the following situations. Explain your reasoning.
a. a high school football game
b. food preperation for the prom
c. playing in the school band
d. lightning in a thunderstorm
e. wearing a pair of sunglasses outside in the sun
The areas within physics are mechanics (motion and its causes), thermodynamics (heat and temperature), vibrations and wave phenomena (specific types of repetitive motions), optics (light), electromagnetism (electricity, magnetism, and light), relativity (particles moving at any speed, including very high speeds), quantum mechanics (behavoir of submicroscopic particles)
the ones i have are playing in the school band- vibrations and wave phenomena because the instruments involve sound, ligtning in a thunderstorm- electromagnetism because lightning is an electrical charge, and wearing a pair of sunglasses outside in the sun- optics because the sunglasses have lenses.
and then how about a high school football game- mechanics because the football spins when you throw it and the players tackle each other and then food preperation for the prom- thermodynamics because you have to get the temperature of the food just right?
Trick question. All involve physics. Remember in the food cooking, chemical changes depend on energy changes within the chemical molecules...this is physics.
Mechanics Motion and its causes, interactions between objects Falling objects, friction, weight, spinning objects
Thermodynamics Heat and temperature Melting and freezing processes, engines, refrigerators
Vibrations and wave phenomena Specific types of repetitive motions Springs, pendulums, sound
Optics Light Mirrors, lenses, color, astronomy
Electromagnetism Electricity, magnetism, and light Electrical charge, circuitry, permanent magnitudes, electromagnets
Relativity Particles moving at any speed, including very high speeds Particle collisions, particle accelerators, nuclear energy
Quantum mechanics Behavior of submicroscopic particles The atom and its parts
2. Identify the area of physics that is most relevant to each of the following situations. Explain your reasoning.
A high school football game = mechanics because football is a sports that we have to interact our feet with the ball.
Food preparation for the prom = thermodynamics because when you preparing a food, you have to cook it first before you can it.
Playing in the school band = vibrations and wave phenomena because playing an school band we have to use an instrument to play and become an music which it also show vibration and sound of something.
Lightning in a thunderstorm = electromagnetism because lightning is an electric light that come down from the sky.
Wearing a pair of sunglasses outside in the sun = optics because sunglasses are lenses that protect our eyes from the UV of the sun.
3. What are the activities involved in the scientific method?
Make observations and collect data that lead to a question
Write our hypothesis and test our hypothesis by doing an experiment
Check our results and correct our hypothesis if needed
Write a conclusions in a form that can be judge by others
4. Gives two examples of ways that physicists model the physical world.
Creating a models or an diagram to make things easier to understand
Use computers programming or small scale replica of the situation
5. Critical Thinking: Identify the area of physics involved in each of the following tests of a lightweight metal alloy proposed for use in sailboat hulls:
Testing the effects of an collision of the alloy: relativity
Testing the effects of extreme heat and cold on the alloy: thermodynamics
Testing whether the alloy can effect a magnetic compass needle: electromagnetism
You have already answered the question correctly in your discussion. Nice work!
Identify area of physics would be the most relevant to each of these situations?
m
a. a high school football game - Mechanics. The motion of the football, the players running, tackling, and throwing the ball all involve motion and its causes, which falls under the domain of mechanics in physics.
b. food preparation for the prom - Thermodynamics. When preparing food, you need to consider heat and temperature to cook, bake, or fry the ingredients properly. Thermodynamics deals with the transfer of heat and energy, which is essential in food preparation.
c. playing in the school band - Vibrations and Wave Phenomena. Musical instruments produce sound through vibrations, which propagate as waves in the air. Understanding the behavior of sound waves and the vibrations of musical instruments falls under the domain of vibrations and wave phenomena in physics.
d. lightning in a thunderstorm - Electromagnetism. Lightning is an electrical discharge caused by the buildup and release of electrical charges in the atmosphere. Electromagnetism is the area of physics that studies electricity, magnetism, and the interaction between them, thereby explaining the phenomenon of lightning.
e. wearing a pair of sunglasses outside in the sun - Optics. Sunglasses have lenses that are designed to manipulate the way light interacts with them. Optics in physics deals with the behavior and properties of light, including how it is reflected, refracted, and absorbed by various materials, which is essential in explaining the use of sunglasses.
a. A high school football game - The relevant area of physics here would be mechanics. Mechanics deals with the motion of objects and the forces acting on them. In a football game, understanding the principles of motion and forces is crucial to analyze the trajectory of the ball, the impact of collisions between players, and the overall movement of the game.
b. Food preparation for the prom - While thermodynamics could be applicable in terms of getting the temperature of the food right, there is another area of physics that is also relevant here. The principles of heat transfer, which fall under thermodynamics, play a role in cooking the food, but there is also an aspect of optics involved. Optics deals with the behavior and properties of light, and in food preparation, the visual appearance of the dishes is often important to create an appealing presentation.
c. Playing in the school band - The relevant area of physics here would be vibrations and wave phenomena. Instruments in a band produce sound through vibrations, and understanding the properties of waves, such as frequency and amplitude, is crucial to produce different musical notes. Additionally, the characteristics of resonance and interference are also applicable in the context of playing in a band.
d. Lightning in a thunderstorm - The area of physics most relevant to lightning in a thunderstorm is electromagnetism. Lightning is a natural electrical discharge, and electromagnetism deals with the behavior of electric charges and their interaction with magnetic fields. Understanding the properties of electric currents and electrical charges is essential to explain the phenomenon of lightning.
e. Wearing a pair of sunglasses outside in the sun - The area of physics most relevant here is optics. Sunglasses have lenses that interact with light, allowing certain wavelengths to be absorbed or blocked, reducing the intensity of light reaching the eyes. Understanding how light interacts with materials, such as lenses, and how it can be refracted, reflected, or absorbed is important when considering the functionality of sunglasses in protecting the eyes from excessive sunlight.
