Energy stored due to an object's position.

When a ball is dropped from a height, what energy transformation occurs as it falls?

Potential energy is transformed into kinetic energy.

Potential energy is transformed into thermal energy.

Thermal energy is transformed into kinetic energy.

Kinetic energy is transformed into potential energy.

Consider a roller coaster at the top of a hill. As it descends, what energy transformation is happening?

Potential energy to kinetic energy

Chemical energy to potential energy

Kinetic energy to potential energy

Kinetic energy to thermal energy

A stretched rubber band, when released, can launch a small object. What energy transformation occurs when the rubber band snaps back?

Potential energy to kinetic energy

Thermal energy to kinetic energy

Kinetic energy to potential energy

Potential energy to thermal energy

Which of the following situations demonstrates kinetic energy being transformed into potential energy?

A coiled spring being compressed.

A person is pushing a wall with all their might, but the wall does not move. Has work been done on the wall?

No, because the wall did not move.

Yes, because a force was applied.

No, because the force was not strong enough.

Yes, because the person exerted energy.

If you lift a heavy box in 10 seconds, and your friend lifts the same box in 20 seconds, who has more power?

You, because you did the work faster.

Neither, power is not related to time.

Your friend, because they took longer.

If you lift a 5 kg box 2 meters up in 4 seconds, and then another 5 kg box 2 meters up in 8 seconds, on which box did you exert more power?

The first box, because you did it faster.

The second box, because it took more time.

You exerted more power on the second box.

The work done is the same, so the power is the same.

The storage of potential energy in dams is a key component of hydroelectric power generation. In the Philippines, where is this commonly observed?

Along major river systems with significant elevation changes

When water flows from a dam and turns turbines, it is an example of potential energy being converted into which other form of energy?

Kinetic energy and then electrical energy

he electricity generated by dams in the Philippines is used to power:

Homes, communities, and industries

Primarily agricultural machinery

Here is a transcript of a video about Narrative Writing. Generate 25 questions. Intro to Narrative Writing What is Narrative Writing? You today, I want to introduce you to the basics of narrative writing. Narrative writing is writing that tells a story. It can be real or imagined, that is, nonfiction or fiction. It has a beginning, middle, and end. That is, it includes the basic elements of a plot exposition, rising action, conflict, climax, falling action, and resolution. And it's full of interesting details. The author's purpose in writing a narrative is to entertain the reader. There are three main types of narrative writing. The first is a personal narrative when a writer shares a true story from his or her own life. We could also say this type of narrative is autobiographical. The second type of narrative is biographical when a writer shares a true story from another person's life. The third type of narrative is fictional. When a writer tells an invented story, short stories, and novels are fictional narratives. The Process of Writing a Narrative While we could add to this list, there are five important parts of a narrative that I especially want you to remember as you write your own narrative. These parts of a narrative include setting, characters, plot, point of view, and dialogue. The first part of a narrative is the setting , where, and when the narrative takes place. The setting affects both the plot and characters in your narrative, so it's important to spend some time brainstorming where, when, and in what conditions your story takes place. The second part of a narrative is the characters , the people, animals or creatures involved in a story. Remember that your story must have a protagonist, the character facing the problem, and an antagonist the character or force causing the problem. Take some time while planning your narrative to focus on your characters beyond the characters names and roles they play in the story. Think about whether you'd like them to be flat with very few character traits or round with many character traits. Also think about which characters in your story will remain static or unchanged, and which characters will be dynamic, undergoing an important change in your narrative. The third part of a narrative is the plot , the sequence of events in a narrative. Take some time to think carefully through your story's plot. How will it begin and how will it end? What conflicts will your characters encounter? What is the climax or turning point of your story? How will the problems be solved? Creating a storyboard or labeling a plot diagram are both good tools for planning your story's plot. The fourth part of a narrative is the point of view , which is the perspective from which a narrative is told. You can choose to write your narrative in first person, writing a personal narrative from your own point of view, or you can choose a character in a fictional narrative to tell your story. Another option is to write your narrative in the third person point of view, telling the story from the perspective of an unseen narrator that is not a character in the story. Finally, the fifth part of a narrative is dialogue. The words the characters speak in your story dialogue can establish the setting, show characterization, foreshadow events, or advance the action in a narrative. Dialogue brings your narrative to life. It's important to review how to punctuate dialogue, following grammatical rules for using quotation marks, commas, and other N marks such as periods and question marks. As you begin writing your narrative, I'll help you break down each step of the process. But hopefully this introduction gives you a basic understanding of what narrative writing is, and hopefully it sparks some ideas for you to begin planning your own narrative.
