Forces and Motion
I. OBJECTIVES
    A. Content Standards           The learners demonstrate an understanding of: Newton’s three laws of motion and uniform circular motion
    B. Performance Standards       The learners shall be able to develop a written plan and implement a “Newton’s Olympics”
    C. Learning Competencies       The learners should be able to:
                                            a. investigate the relationship between the amount of force applied and the mass of the to the amount of change in the object’s motion;
                                            b. infer that when a body exerts a force on another, an equal amount of force is exerted back on it;
                                            c. demonstrate how a body responds to changes in motion;
                                            d. relate the laws of motion to bodies in uniform circular motion;
                                   e. infer that circular motion requires the application of constant force directed toward the center of the circle.
