Terminal velocity is the maximum speed an object reaches when falling through a fluid (such as air or water), where the force of gravity is balanced by the drag force (air resistance or fluid resistance). At this point, the object stops accelerating and continues to fall at a constant speed.

### Key Points:

1. **Gravity**: The force pulling the object downward.

2. **Drag Force**: The resistance force exerted by the fluid opposing the object's motion. It increases with the object's speed.

3. **Equilibrium**: Terminal velocity occurs when the gravitational force equals the drag force, resulting in no net force and thus no further acceleration.

### Factors Affecting Terminal Velocity:

- **Mass**: Heavier objects have a higher terminal velocity because gravity exerts a greater force on them.

- **Cross-Sectional Area**: Objects with a larger surface area experience more drag, reducing terminal velocity.

- **Drag Coefficient**: A measure of how aerodynamic the object is. A lower drag coefficient means less resistance and a higher terminal velocity.

- **Fluid Density**: Higher density fluids (like water) create more drag, reducing terminal velocity compared to lower density fluids (like air).

Lencho is a fictional character from the short story "A Letter to God," written by the Mexican author Gregorio López y Fuentes. He is portrayed as a hardworking and optimistic farmer who lives in a rural area in Mexico. Lencho is characterized by his deep faith in God and his determination to provide for his family, despite the harshness of nature and the challenges he faces.

In the story, Lencho works tirelessly on his farm, and he relies heavily on a good harvest to sustain his family. When a heavy hailstorm devastates his crops, he feels despair but remains hopeful. In his desperation, he writes a letter to God, asking for money to help him through the tough times. Lencho's unwavering faith and his belief that God will respond to his plea highlight his personality as a man of faith and resilience, though he also demonstrates naivety regarding the response he expects from the divine.

Improving student engagement during online tutoring sessions is essential for enhancing learning outcomes. Here are some effective strategies:

1. Interactive Tools: Use interactive tools like quizzes, polls, and virtual whiteboards to make lessons more engaging. Platforms such as Kahoot!, Quizizz, or Google Jamboard can increase participation.

2. Incorporate Multimedia: Utilize videos, infographics, and animations to cater to different learning styles. Multimedia can help make complex topics more relatable and interesting.

3. Gamification: Introduce game-like elements into the sessions, such as point systems, badges, or challenges, to motivate students and make learning fun.

4. Breakout Sessions: Utilize breakout rooms for small group discussions or activities. This allows for more personal interaction and encourages peer engagement.

5. Regular Check-ins: Ask open-ended questions and encourage students to share their thoughts. Regularly check in on their understanding and feelings about the material.

6. Set Clear Goals: At the beginning of each session, set clear, attainable goals. This gives students a sense of direction and purpose, which can enhance focus and engagement.

7. Personalization: Tailor sessions to meet individual needs and interests. Understanding what motivates each student can make the learning experience more relevant and engaging.

8. Vary Activities: Change up the types of activities during a session. Mix lectures with discussions, problem-solving, and collaborative projects to keep things dynamic.

9. Encourage Student Responsibility: Give students roles (such as discussion leader or note-taker) during the session. This creates ownership and encourages active participation.

10. Utilize Real-World Connections: Relate concepts to real-life scenarios that interest students. Making lessons relevant to their lives can greatly enhance engagement.

11. Feedback and Reflection: End sessions with reflection questions to gauge understanding and gather feedback on what worked and what didn’t. Adjust future sessions based on this input.

12. Stay Positive and Encourage: Create a supportive and positive environment. Celebrate small successes to boost confidence and motivation.
