MODULE IN SCIENCE 8 First Quarter Week 1 MOST ESSENTIAL LEARNING COMPETENCY Investigate the relationship between the amount of force applied and the mass of the object to the amount of change in the object’s motion (S8FE-Ia-15)

OBJECTIVES: 1. 2. 3. 4.

explain the law of inertia; cite situations where the law of inertia applies; state Newton’s second law of motion- law of acceleration; solve problems involving the law of acceleration.

WHAT’S IN In your Grade 7 module, you have learned about the basic concept of motion. Can you still remember some terms about it? Let us read the statements below 1. Speed refers to the rate of change in distance. 2. Velocity is the rate and direction of an object's movement. 3. Motion is a continuous change in position with respect to a reference point for a particular time interval. 4. Distance refers to the length of the entire path that the object travelled. 5. Displacement refers to the shortest distance between the object’s two positions, like the distance between its point of origin and its point of destination. It is indicated by direction.

WHAT IS IT Inertia Newton's first law of motion is often stated as An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Two Clauses and a Condition There are two clauses or parts to this statement one that predicts the behavior of stationary objects and the other that predicts the behavior of moving objects. The two parts are summarized in the diagram....
