1) Forces
Description
In this video lesson, Paul Andersen reviews importance concepts related to forces, which are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates, then a force is present.--Publisher.
Description
In this video lesson, Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action), an equal and opposite force (Reaction) is applied to the original object. Several scenarios are described to show these action-reaction pairs. Free-body diagrams are used to describe all of the external forces from these interactions.--Publisher.
Description
In this video lesson, Paul Andersen compares and contrasts elastic and inelastic collisions. In all collisions, the linear momentum will be conserved. In an elastic collision, the kinetic energy of the objects will also be maintained. Several examples and demonstrations are included.--Publisher.
Description
In this video lesson, Paul Andersen explains how mechanical energy added or removed from a system results from work. For work to occur, a force must act parallel to the displacement of the system. Since work and energy are equivalent, the work-energy theorem allows for calculating the work as the change in kinetic energy. A force-displacement graph can be used to calculate the work done on the system.--Publisher.
Description
In this video lesson, Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a system, the center of mass of the system will experience no acceleration.--Publisher.
Description
"In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be accountable for interactions involving an increase in volume over time."--

Description
In his bestselling E=mc2, David Bodanis led us, with astonishing ease, through the world's most famous equation. Now, in Electric Universe, he illuminates the wondrous yet invisible force that permeates our universe and introduces us to the virtuoso scientists who plumbed its secrets. For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began...

This 15-question physics review will help you refresh and practice the concepts related to energy transfer, energy storage, elastic energy, kinetic energy, potential energy, dissipated energy, work energy theorem, interpretation of force position graphs, conservative forces, non-conservative forces, conservations of energy problems, and power.

This second 15-question physics review will continue to help you refresh and practice the concepts related to energy transfer, energy storage, elastic energy, kinetic energy, potential energy, dissipated energy, work energy theorem, interpretation of force position graphs, conservative forces, non-conservative forces, conservations of energy problems, and power.
15) Forms of Energy
Description
Energy is never created nor destroyed; it is just transferred from one form to another. This video production uses an engaging presenter and familiar objects and scenarios to explore different forms of energy, their effects on objects and processes, and conversion from one form to another. Sections include what is energy, kinetic energy (including electrical, radiant and sound), potential energy and energy transformations. Students of Science at lower...

Description
"This book describes the physics of baseball and softball, assuming that the reader has a background in both physics and mathematics at the high school level. The physics is explained in a conversational style, and illustrated with experimental results obtained both in the laboratory and in the field. Simple equations are also used in order to model the experimental results and to test whether the explanations are actually valid. The subject matter...
