Provides a method of solving vector and force problems that is less complicated for the learner. Gives several examples concerning projectiles and inclined planes. (MVL)

An exercise that gives students a chance to use the equations of state for both an ideal gas and for an adiabatic process in determining the points at which heat flow reverses direction and at which the working substance reaches its maximum temperature is demonstrated. (KR)

The data from measurements of the density of tungsten, steel, aluminum, and PVC spheres are used to extrapolate the infinite density of something such as a neutron star. An apparatus that allows for precision measurements is described. A discussion on error analysis is appended. (KR)

An activity in which students use a rubber band and flexible straws to pull a dynamics cart so that the cart has a consistent angle and, therefore, a consistent horizontal component of force is described. A copy of the handout for the activity is included. (KR)

As part of a campus-wide, externally funded project to increase performance in, enthusiasm for, and retention within STEM disciplines, we developed an interdisciplinary, team-taught first-year seminar course. The construction and delivery of this course was designed to show the relevance of selected general chemistry topics such as matter and…

Research indicates that novice problem solvers represent and organize knowledge differently from experts. The novice engaged in problem solving activities is of interest to educators because efficient instruction reduces the differences between initial intuitive knowledge representations and the true concepts to be mastered. A particular cognitive…

Five segments of the Self-Paced Physics Course materials are presented in this problems and solutions book for use as the first part of student course work. The subject-matter topics are related to significant digits, vectors, dimensions, dot and cross products, speeds, velocities, problem solving procedures, projectiles, Newton's laws, and…

Five segments of the Self-Paced Physics Course materials are presented in this problems and solutions book for use as the second part of student course work. The subject-matter topics are related to circular motion, work, power, kinetic energy, potential energy, conservative forces, conservation of energy, spring problems, center of mass, and…

Four segments of the Self-Paced Physics Course materials are presented in this problems and solutions book for use as the third part of student course work. The subject-matter topics are related to impulses, inelastic and elastic collisions, two-dimensional collision problems, universal constant of gravitation, gravitational acceleration and…

Advocates changing the role of secondary school science from one of theory verification and problem solving to the formulation and acceptance of hypotheses for observed phenomena. Provides an example of the procedure using Hooke's Law. (CP)

Described is an activity in which students examine data collected from an official report of a train accident to evaluate the conclusions of the official investigation. Quotations from the records and calculations used in this activity are included. (CW)

An example of how a traditional activity on motion and acceleration can be adapted to the learning-cycle format is described. The three challenge statements given to students to solve are provided. The key learning-cycle steps of exploration, expansion, and extension are discussed. (KR)

Uses projectile motion to explain the two roots found when using the quadratic formula. An example is provided for finding the time of flight for a projectile which has a negative root implying a negative time of flight. This negative time of flight also has a useful physical meaning. (MVL)

In this study, the effects of teacher-directed and self-directed problem-solving strategies on students' attitudes toward physics were explored. Problem-solving strategies were used with the experimental group, while the control group was instructed using traditional teaching methods. The study was conducted with 270 students at various high…

In a study to assess how effectively undergraduate physics studies have prepared students for the workplace, we attempted to locate and interview traditional 3-year or 4-year physics students who had graduated in the past five years (2000 to 2004), and the employers of these graduates. The study was limited to recent graduates who have majored in…
