The language of physics is mathematics. (return to top) |
|
|
1. Physics relies on standardized units to define properties and relationships among physical quantities. (AKSci - B.1) |
• Use and convert units within an appropriate system of measurement (emphasize the SI system of measurement). |
|
2. Physical phenomena can be analyzed mathematically. (AKSci - B.1, D.1) |
• Calculate the horizontal and vertical velocity components of a thrown object. |
|
Motion in one and two dimensions can be described mathematically. (return to top) |
|
|
• Construct graphs representing one and two-dimensional motion. • Design and execute an experiment proving that motion on a ramp is accelerated. |
|
|
Net forces cause masses to change their motion. (return to top) |
|
|
• Identify and contrast examples of accelerated and constant velocity motion. |
|
|
1. Free Body Diagrams specify which forces are involved in specified situations. (AKSci - A.6) |
• Construct a Free Body Diagram of an object in uniform circular motion. • Using Newton's Universal Gravitational Law, graph the motion of a satellite around Earth. |
|
An object with energy can do work. (return to top) |
|
|
1. Total energy can neither be created nor destroyed. (AKSci - A.8b) |
• Calculate the speed of a falling object using Conservation of Mechanical Energy. • Identify the flow of energy through a system. |
|
Moving objects possess momentum (return to top) |
|
|
1. Total momentum can neither be created nor destroyed. (AKSci - A.6) |
• Demonstrate that total momentum remains unchanged in a collision. • Calculate the changes in motion when two objects collide. • Build a mathematical model of a collision in which neither energy nor momentum changes. |
|
Waves are generated by objects oscillating in simple harmonic motion. (return to top) |
|
|
1. It is common for energy to be transferred by waves. (AKSci - A.6) |
• Describe how water waves and sound waves are created by oscillating sources. |
|
2. Waves can be categorized by many of their characteristics. (AKSci - A.6) |
• Identify the qualities of a good oscillator. • Calculate the wavelength of a specific tuning fork. |
|
Interactions among particles with electric charge are responsible for the structure of matter. (return to top) |
|
|
1. Electric charge appears in two types: positive and negative, which cannot be created or destroyed. (AKSci - A.1) |
• Determine the magnitude and polarity of electric charge of an object. |
|
2. Interactions between charged particles occur via their respective electric fields. (AKSci - A.2) |
|
|
• Calculate the current and voltage for simple circuits and compare these values to those measured in actual circuits. |
|
|
Magnetism, like electric charge, is a fundamental property of most matter. (return to top) |
|
|
1. Magnetic charge appears in two types, or poles: north and south. (AKSci - A.2) |
• Compare the effect on a moving electric charge of a magnetic and electric field. • Experiment with the magnetic fields of various magnets. |
|
Accelerated electric charges generate self-propagating electric and magnetic fields: electromagnetic radiation. (AKSci - A.2) (return to top) |
|
|
• Calculate the wavelength of electromagnetic radiation produced by an electron moving in a circle. |
|
|
When light's speed changes, light's direction changes. (AKSci - A.3) (return to top) |
|
|
• Compare the measured and calculated location of an image created by a lens and mirror. |
