✏️ 2. Fill in the Blanks
1. Energy that an object has because of its motion is called energy.
2. Stored energy, often due to an object's position or state, is known as energy.
3. A stretched rubber band or a spring that is compressed has energy.
4. When a roller coaster car goes down a steep hill, its potential energy is converted into energy.
5. The higher an object is lifted off the ground, the more energy it gains.

2. Describe a simple situation where an object has a lot of potential energy.
💡 Suggested Answer: A book sitting on a high shelf, a child at the top of a slide, or water held back by a dam.
🎯 5. Multiple Choice
1. Which of the following objects has the most kinetic energy?
2. What type of energy does a stretched rubber band possess?
3. When a pendulum swings, at what point does it have the most potential energy?
📝 6. Open-Ended Questions
1. Explain the main difference between kinetic energy and potential energy. Provide a simple example to illustrate your explanation.
💡 Solution Steps:
Kinetic energy is the energy of motion. Any object that is moving has kinetic energy. Potential energy, on the other hand, is stored energy. It's the energy an object has due to its position or state. For example, a rock held high in the air has potential energy because of its height. If you drop the rock, it starts to move, and its potential energy changes into kinetic energy as it falls.
2. Imagine a child on a playground slide. Describe the energy changes that occur as the child sits at the top, slides down, and then lands at the bottom.
💡 Solution Steps:
1. <strong>At the top of the slide:</strong> The child has maximum potential energy because of their height. They are not moving, so their kinetic energy is minimal.
2. <strong>Sliding down the slide:</strong> As the child moves down, their potential energy decreases, and this stored energy is converted into kinetic energy. The child speeds up.
3. <strong>At the bottom of the slide:</strong> The child has reached the lowest point, so their potential energy is at its minimum. Their kinetic energy is at its maximum just before they stop moving.
3. A bow and arrow are used to shoot an arrow. Describe the energy transformations that happen from when the bowstring is pulled back to when the arrow flies through the air.
💡 Solution Steps:
1. <strong>Pulling the bowstring back:</strong> When the bowstring is pulled back, work is done to store energy in the stretched bow. This is elastic potential energy.
2. <strong>Releasing the bowstring:</strong> When the bowstring is released, the stored elastic potential energy is rapidly converted into kinetic energy, which is transferred to the arrow.
3. <strong>Arrow flying through the air:</strong> The arrow now has a lot of kinetic energy, which keeps it moving forward. As it flies, some of its kinetic energy is gradually converted into thermal energy (due to air resistance) and sound energy, causing it to slow down over distance.
