The video resource "Nuclear Physics: Crash Course Physics #45" is included in the "Statistics" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Mr. Andersen contrasts nuclear reactions to chemical reactions. He explains the four main forces of nature; including gravity, electromagnetism, strong, and weak nuclear forces. He also explains how fusion differs from fission.

Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and protons, as well as charge.

The purpose of this video tutorial is to review a couple ways in which we think about numbers. Thinking in terms of street numbers, money in bank accounts, and quantum particles (e.g. Bose-Einstein condensate) is contrasted with focusing on associating numbers with distinguishable manipulatives, as is more familiar in K-8 courses. This video concludes with a reminder that the symbol "infinity" is not, itself, a number.

Paul Andersen explains how object interactions can add or remove mass or energy from a system.

In this video Paul Andersen explains how a system can be viewed as an object and an object can be viewed as a system.

In this video Paul Andersen explains the differences between a system and an object. Depending on the scale it often times easies to view a system as an object if the constituent parts aren't relevant to the question being asked.

Part 2 of offshore hydromechanics (OE4630) involves the linear theory of calculating 1st order motions of floating structures in waves and all relevant subjects such as the concept of RAOs, response spectra and downtime/workability analysis.

Offshore Hydromechanics includes the following modules:1. Hydrostatics, static floating stability, constant 2-D potential flow of ideal fluids, and flows in real fluids. Introduction to resistance and propulsion of ships. Review of linear regular and irregular wave theory. 2. Analytical and numerical means to determine the flow around, forces on, and motions of floating bodies in waves. 3. Higher order potential theory and inclusion of non-linear effects in ship motions. Applications to motion of moored ships and to the determination of workability. 4. Interaction between the sea and sea bottom as well as the hydrodynamic forces and especially survival loads on slender structures.

In this extension to the Ohm's Law I activity, students observe just how much time it takes to use up the "juice" in a battery, and if it is better to use batteries in series or parallel. This extension is suitable as a teacher demonstration and may be started before students begin work on the Ohm's Law I activity.

Students work to increase the intensity of a light bulb by testing batteries in series and parallel circuits. They learn about Ohm's law, power, parallel and series circuits, and ways to measure voltage and current.

This course covers the major topics of mechanics including momentum and energy conservation, kinematics, Newton's laws and equilibrium. The major emphasis is to develop critical analysis, problem solving and scientific reasoning skills by considering numerous different systems and interactions, solving problems and discussion. We will use a systematic approach based on modeling systems by application of basic physics principles, making assumptions, utilizing multiple representations (not just mathematical) in order to become proficient at problem solving. Lab work is required and is designed to help you develop a questioning approach to physical situations, distinguishing the significant behaviors from the less significant behaviors of a system under study.

A course for non-science majors that is a survey of the central concepts in physics relating everyday experiences with the principles and laws in physics on a conceptual level.Upon successful completion of this course, students will be able to: Describe basic principles of motion and state the law of inertia. Predict the motion of an object by applying Newton's laws when given the mass, a force, the characteristics of motion and a duration of time. Summarize the law of conservation of energy and explain its importance as the fundamental principle of energy as a "law of nature". Explain the use of the principle of Energy conservation when applied to simple energy transformation systems. Define the Conservation of Energy Law as the 1st Law of Thermodynamics and State 2nd Law of Thermodynamics in 3 ways. Outline the limitations and risks associated with current societal energy practices,and explore options for changes in energy policy for the next century and beyond. Describe physical aspects of waves and wave motion. Explain the production of electromagnetic waves, and distinguish between the different parts of the electromagnetic spectrum.

The video resource "Optical Instruments: Crash Course Physics #41" is included in the "Statistics" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

This video is from the Khan Academy subject of Science on the topic of Physics and it covers Optimal angle for a projectile part 1.

Why work from expansion is the area under the curve of a PV-diagram

Light up your love with paper circuits this Valentine’s Day—no soldering required! Create a sure-to-impress flashing birthday card or design a light-up Christmas card—all with paper circuits! In this activity, students are guided through the process to create simple paper circuitry using only copper tape, a coin cell battery, a light-emitting diode (LED) and small electronic components such as a LilyPad Button Board. Making light-up greeting cards with paper circuitry is great way to teach the basics of how circuits function while giving students an outlet to express their artistic creativity.

Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.
