The physics of vertical jumping is described as an interesting illustration for motivating students in a general physics course to master the kinematics and dynamics of one dimensional motion. The author suggests that mastery of the physical principles of the jump may promote understanding of certain biological phenomena, aspects of physical…

Discusses the applications of the principles of mechanics to rock climbing techniques. Provides illustrations showing the applied force vectors. (YP)

The answers from test questions on circular motion are analyzed in terms of the misunderstandings of resultant force, kinematics, interaction, and centrifugal force. (DS)

Shows how the thermal power developed by friction is exactly half the supplied power in the general case of a variable force of friction. Investigates the mechanism whereby one-half the input energy is dissipated as heat using mathematical expressions. (YP)

The common definition is shown to be false. A modern definition must be based on the first and second laws of thermodynamics and in terms of a set of algebraic expressions written in such a way that their sum does not change when a system is isolated. (DF)

Presents the theoretical explanation of the observation that when a pen that is stuck in a hard rubber ball and dropped, the pen may bounce to several times the dropped height. Includes the procedure and models created to explain the observations. (DS)

Centrifugal Force is described and defined in terms of the underlying theory and terminology with the aid of rigorous analysis of this phenomenon. (DS)

The theory of plate tectonics is discussed as it relates to connection, purported to be the driving force involved in the movements of the earth's crust. (SA)
