2 Adopted: 12/17/03 SUBJECT AREA - SCIENCE COURSE DESCRIPTION: Like Physics, Physics Honors provides students with the opportunity to study the underlying patterns in the physical universe. This is a broad subject, with topics ranging from the forces influencing motion to sound and light. Students have the opportunity to study principles of physics through experiment, calculations, demonstrations, and projects. Topics will be covered with more depth and more involved mathematics compared to the regular physics course. COURSE GOALS: Upon completion of the course, student will: 1. Develop problem solving skills. 2. Students will recognize the real world applications of physics principles. TETBOOK MATERIALS: Physics Principles with Applications, 6ed, Douglas C.

Differentiates between average speed and instantaneous speed. N/A 1.0 Selected Constructed Performance Product % of class time 1.2 Knows that when forces are balanced, no acceleration occurs; thus an object continues to move at constant velocity or stays at rest (Newton s First Law) Knows how to apply the law F = ma to solve one-dimensional motion problems that involve constant forces (Newton s Second Law). 1.3 Page 3 of 17

4 1.4 Knows that when one object exerts a force on a second object, the second object always exerts a force of equal magnitude and in the opposite direction on the first object (Newton s Third Law). Can apply Newton s 2 nd and 3 rd Laws to solve multi-body problems Knows the relationship between the universal law of gravitation and the effect of gravity on an object at the surface of the Earth. 1.6 Knows applying a force to an object perpendicular to the direction of its motion causes the object to change direction but not speed. 1.7 Knows circular motion requires the application of a constant force directed toward the center of the circle Knows Newton s laws are not exact, but provide very good approximations unless an object is moving close to the speed of light or is small enough that quantum effects are important. 1.EB.1 Page 4 of 17
