Law of inertia: -Newton’s first law of motion states that an object at rest stays at rest, and an object in motion stays in motion with constant velocity, unless acted upon by an external net force.

Law of inertia: -Newton’s first law of motion states that an object at rest stays at rest, and an object in motion stays in motion with constant velocity, unless acted upon by an external net force. This is because of inertia or the natural tendency of every object to resist a change in their state of motion. ACTIVITY 1: MAGIC OR INERTIA? Guide questions: 1. When you pull the bandana off the table, which bottle tipped off? Bottle C 2. Which bottle is the sturdiest and did not move much?’ Bottle A 3. Which of the three bottles has the greatest mass than the rest? Bottle A 4. Which bottle has the greatest inertia? Bottle A 5. Based on this activity, how can you relate the inertia of the bottle with its mass? More mass :more inertia Newton’s second law of motion - states that the acceleration of an object is directly proportional to the net force applied on it and is inversely proportional to its mass. -Acceleration is the rate of change of the velocity of an object with respect to time. ***In simpler terms, as the net force applied on an object increases, its acceleration also increases and vice versa. On the contrary, as the mass of an object increases, its acceleration decreases. On the other hand, if its mass decreases, acceleration increases. This is also known as the law of acceleration. 4 2 10 Activity 2:
