NAME OF TEACHER: _VERNA N. MACASIEB______________ LEARNING AREA: SCIENCE

GRADE LEVEL: 9_____________ QUARTER: 4th WEEK: _____4______

MODULE NO. AND TITLE: Module 2 Momentum and Impulse

MELC/S:

● Describe the horizontal and vertical motion of a projectile and investigate the relationship between the
angle of release and the height and range of the projectile. S9FE-IVa-34 and S9FE-IVa-35
● Relate impulse and momentum to collision of objects (e.g., vehicular collision) (S9FE–IVb–36) and infer
that the total momentum before and after collision is equal. (S9FE–IVc–37)

CONTENT STANDARD (CS)

Projectile motion, impulse and momentum, and conservation of linear momentum.

PERFORMANCE STANDARD (PS)

Propose ways to enhance sports related to projectile motion.
