Content standard

The learners learn that 1. Physics is fundamental to understanding the natural world in a scientific way and leads to the development of many applications that benefit society; 2. measuring should be done precisely and accurately, and must be expressed correctly; and 3. qualitative, quantitative, and graphical analysis of motion provide complementary ways to understand, describe, and predict motion.

Performance standard

By the end of the quarter, learners properly measure and use pertinent units, compute resultant vectors, and analyze motion graphs. They explain, calculate, and analyze one-dimensional, two-dimensional, and relative motion in practical contexts and solve problems using kinematic equations. They also describe and explain how basic physics principles are applied to describe and make predictions about motion in everyday situations and scenarios. Suggested Performance Task ● Prove through experimentation, data gathering, graphical representation, and analysis that vertical and horizontal motion are independent of each other in projectile motion.
