You are driving a car down a straight highway when you come upon a sudden accident. You slam on your brake to avoid hitting the car in front of you. Describe any changes in the motion of your car in terms of velocity and acceleration. Feel free to embellish your account of values of your own choosing.
 
In addition to defining the concepts,  you must illustrate them by applying them to an example.  Your example must contain substantive details. 
Support the information presented in your initial post with appropriate references.
There are two types of numeric quantities in physics: vectors and scalars. Understanding these two concepts allow you to more successfully describe and understand physical phenomena.
A scalar quantity is a magnitude that describes a measurement or amount. For example, the temperature is a scalar quantity. Temperature is a measurement of the relative hotness or coldness of an object and it doesn’t have a directional dependence. Speed is another example of a scalar quantity as a measurement of how fast an object is moving.
Velocity is a vector composed of both speed and direction (example: car moving 30 mph towards the East). In this course, we will not explore vector algebra. Instead, we will stick with a one-dimensional analysis where the direction is indicated by either (+) or (-). Acceleration is also a vector because it is defined as the time rate of change in velocity. Since velocity is speed and direction, that means acceleration can be a change in speed, a change in direction, or both changes in speed and direction relative to time.
Force is also a vector quantity. Newton’s second law defines force as the product of mass (a scalar) and acceleration (a vector) so the result is a force vector. By definition, a force causes objects to accelerate, so this means that when a force is applied the acceleration can be a change in speed, a change in direction, or a change in both speed and direction.
The acceleration due to gravity at the Earth’s surface is 9.8 m/s^2. It is a vector that points towards the center of the Earth. Weight is a force defined as the product of mass and acceleration due to gravity. That makes weight a vector as well.

Research how the system works to convert energy generated at one time for storage and then can be used at a later time to generate electricity for the consumer grid. Heat or Internal Energy Storage–Molten silicon thermal energy storage, molten salt thermal energy storage
Identify the type of energy      that is stored (for example, gravitational potential energy, thermal      or internal energy, elastic potential energy, kinetic energy, chemical      energy, etc). 
Estimate how much energy can be      stored based on example systems in use or proposed. (Note: you might      need to learn what some of the common units are for such quantities, such      as a kilowatt-hour or kWh, British Thermal Unit, or btu, instead of      joules.) 
Identify the pros and cons of      the system.
Problems are encountered when the shift of energy production goes from burning fossil fuels to renewable sources of energy, such as wind and solar. The time of peak energy production does not always correspond to the time of peak demand for energy. For example, solar energy can only be generated during the day, when it’s not cloudy. However, a lot of electricity is used at night. Scientists and engineers are working hard to develop a variety of energy storage systems to allow the energy produced at one time to be used to generate electricity at other times.

While traveling in the engine of a train, you are given the opportunity to activate the horn.  How is the sound you hear different someone near the tracks ahead of your train? How is the sound you hear different from someone in a car traveling next to the tracks at the same velocity?
This week, you will study the relationship between sound and the material in which the sound wave is disseminated. The speed of sound in one material may be greater than in another material due to changes in material properties. For example, a material’s rigidity and/ or density can play a role. 
Sound waves and mechanical oscillations are common in many types of phenomena that you encounter daily. Musicians have an understanding of the characteristics of the sounds produced by their instruments, and this could create new ways for them to be creative with their art. Sonograms are used in technology, and ultrasounds are vitally important in medicine. Seismographs and sonar are sound wave-based technology that allows scientists and engineers to study the characteristics of the earth and under the sea. Technology-based on sound waves is used to enhance and improve our lives in many ways that are not obvious. In this unit and discussion, you will explore the science behind sound waves and their applications

Assignment Content Competency Connect the principles of electricity, magnetism

Assignment Content
Competency
Connect the principles of electricity, magnetism, and light to modern applications of physics.
Student Success Criteria
View the grading rubric for this deliverable by selecting the “This item is graded with a rubric” link, which is located in the Details & Information pane.
Instructions
In a two-page paper, identify the physics principles contained within the following scenario. Explain how these principals connect to electricity, magnetism, or light in modern applications in physics. Finally, consider the different concepts in which James Clerk Maxwell did research, and give an example of one of these concepts in use in your life. For instance, Maxwell’s research led to the development of radio waves. If you listen to a radio, then you are using Maxwell’s research. Provide another example from your own experience, compare, and contrast your scenario to the provided scenario below.
Scenario
Mandy took a trip to Rome, Italy. Once landed and inside the terminal, she turned her cell phone back on, but it was not charged. She found a charging station with a USB adaptor port. The USB was universal, providing 5 volts in any country you were in, and a small red LED next to her phone’s screen told her the phone was successfully charging. This USB port seemed to have very high amperage, meaning it charged her phone quickly. She was aware, though, that almost all of Italy’s electricity was generated by burning fossil fuels, and thus she was determined after this to use the portable solar charger she had bought rather than wall electricity.
