Inertia (Science Says)/English Transcript

Intro
Doc Reina: Why do we suddenly move forward when we stop our car, and backward when we start it? Today, Science Says...Inertia.

The Experiment
Doc Reina: We need a board, one egg, tissue tube, and a glass of water. When I remove the board, what will happen?

a. The egg will flow away (titilapon ang itlog),

b. The egg will fall into the glass (mahuhulog ang itlog sa baso)

o c. The tissue tube and itlog will fall into the glass (mahuhulog ang tissue tube at itlog sa baso)

The law of Inertia is one of the three laws by Isaac Newton. Based on this, one thing can move, if there are no other forces that prevent it. It will remain in motion if there are no other things that make it move.

(the egg falls into the water, but not the tissue tube)

Doc Reina: (laughs) Because Science Says...Inertia, the correct answer is letter B, the egg will fall into the glass.

Explanation
Doc Reina: When I removed the board, the tissue tube followed it, but the egg is stuck in that position due to inertia, and gravity. It fell onto the glass. Inertia is also what we face when in a car. If we suddenly move the car, our body will go backwards because it prefers to remain in its original position, not moving. If we, stop moving, our body will fall forward.
