1 ) Investigate and analyze, based on evidence obtained through observation or experimental design, the motion of an object using both graphical and mathematical models (e.g., creating or interpreting graphs of position, velocity, and acceleration versus time graphs for one- and two-dimensional motion; solving problems using kinematic equations for the case of constant acceleration) that may include descriptors such as position, distance traveled, displacement, speed, velocity, and acceleration.

[SC2015] PHYS (9-12) 5 :

5 ) Construct models that illustrate how energy is related to work performed on or by an object and explain how different forms of energy are transformed from one form to another (e.g., distinguishing between kinetic, potential, and other forms of energy such as thermal and sound; applying both the work-energy theorem and the law of conservation of energy to systems such as roller coasters, falling objects, and spring-mass systems; discussing the effect of frictional forces on energy conservation and how it affects the motion of an object).

[SC2015] PSC (9-12) 7 :

7 ) Analyze and interpret data for one- and two-dimensional motion applying basic concepts of distance, displacement, speed, velocity, and acceleration (e.g., velocity versus time graphs, displacement versus time graphs, acceleration versus time graphs).

[SC2015] PSC (9-12) 8 :

8 ) Apply Newton's laws to predict the resulting motion of a system by constructing force diagrams that identify the external forces acting on the system, including friction (e.g., a book on a table, an object being pushed across a floor, an accelerating car).

[SC2015] PSC (9-12) 11 :

11 ) Design and conduct investigations to verify the law of conservation of energy, including transformations of potential energy, kinetic energy, thermal energy, and the effect of any work performed on or by the system.

This is a lesson presenting energy and work. It covers: types of energy, forms of energy, work, law of conservation of energy, and renewable and nonrenewable energy sources. In the activities section, one will find links to Internet sites that explore concepts of energy and work. Interactive labs are also included in this lesson. The lesson can serve as a student-led or teacher-led lesson. It gives a brief statement of facts; therefore, the teacher must provide expansions, if needed. The expansions could come from the Internet sites since many of them go into more detail about the concepts. The teacher will also be expected to supply some form of assessment for the lesson.

We talk a lot about bridges in Physics. Why? Because there is a lot of practical physics that can be learned from the planning and construction of them. This video discusses simple harmonic motion, oscillation, resonance and how these relate to the problems with the Millennium Bridge.

When you hear the word, "work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics. In this video, Dr. Shini is going to walk us through it. She will also discuss energy and power.
