2. How does relative velocity apply in everyday situations, such as driving on a road?

3. What are some examples of the use of relative velocity in sports, such as soccer or motorsports?

4. How is relative velocity important for road safety?

5. How do the concepts of relative velocity change when considering movements in different directions?

Development

Duration: 70 - 80 minutes

The purpose of this stage of the lesson plan is to provide an active and practical learning experience, where students apply the concepts of relative velocity using digital tools and modern technologies. The activities are designed to be highly engaging and contextualized with the students' reality, encouraging collaborative and creative use of digital resources.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Virtual Influencer Race 🚗💨

> Duration: 60 - 70 minutes

- Objective: Apply the concepts of relative velocity in a practical and digital activity, encouraging the use of technological tools to solve real problems.

- Description: Students will create a simulation of a car race on a social media platform (like Instagram or TikTok). They must model and calculate the relative speed between cars of different digital influencers and post the results as part of an interactive challenge.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group will choose two famous digital influencers known for their passion for cars.

• Using racing simulation apps or simply videos of real races available on the internet, each group must select clips where both influencers are in motion.

• Students should use video editing software (it can be something simple like TikTok or Instagram's editor) to overlay the videos and calculate the relative velocity between the cars using the formulas studied.

• The results and calculation methods must be presented in a post or video on social media with a specific hashtag for the activity, for example, #RelativeVelocityPhysics.

• Each group must comment on the posts of other groups, discussing the methods used and the results obtained.

Activity 2 - Space Mission: Calculating Relative Velocities 🚀🌌

> Duration: 60 - 70 minutes

- Objective: Contextualize the concept of relative velocity in the scenario of space missions, using augmented reality technology to facilitate visualization and comprehension of the problems.

- Description: Students will simulate a space mission where they must calculate the relative velocity between spacecraft and satellites. Using augmented reality (AR) software, they will be able to visualize and interact with three-dimensional models to facilitate understanding of the concepts.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group will use an AR app available on their phones (like Google Expeditions) to visualize models of spacecraft and satellites in motion.

• Students must select a scenario where two spacecraft or a satellite and a spacecraft are moving in the same direction.

• Using the relative velocity formulas, each group must calculate the relative velocity between the selected celestial bodies.

• The results and methodology must be recorded in a digital presentation, using tools like Google Slides or Prezi.

• Each group presents its results to the class, explaining in detail its calculations and the importance of the concept of relative velocity in space missions.

Activity 3 - The YouTubers Race: Who is Faster? 📹🏎️

> Duration: 60 - 70 minutes

- Objective: Use digital and motion analysis tools to apply concepts of relative velocity in a racing scenario, encouraging critical and collaborative analysis.

- Description: Students will analyze videos of races between famous YouTubers using video editing tools and motion analysis software. The task is to calculate the relative velocity between the participating cars and determine the winner based on physical calculations.

- Instructions:

• Divide the students into groups of up to 5 people.

• Each group will choose videos of races between famous YouTubers available on platforms like YouTube.

• Using video editing software and motion analysis tools (like Tracker or similar), students will analyze the videos to measure the speed of each participating car.

• Students must calculate the relative velocity between the cars using the studied formulas and determine which YouTuber would be the winner based on the calculations.

• The results must be presented in an explanatory video, where each group explains the analysis process and the calculations performed.

• The videos will be shared on a YouTube channel created for the class, and each group must comment on the videos of other groups, discussing the accuracy of the calculations and the methodologies used.

Feedback

Duration: 15 - 20 minutes

The purpose of this stage of the lesson plan is to foster a deep and collaborative reflection on the concepts learned, promote communication skills and constructive feedback among students, and reinforce the practical application of knowledge through discussion and evaluation of the activities carried out.

Group Discussion

Facilitate a group discussion with all students. Ask each group to briefly share their experiences while conducting the activity. Suggest that they start by discussing the methods they used to calculate relative velocity, the challenges they faced, and how they overcame them. Encourage them to make connections between the digital activities performed and the theoretical concepts of kinematics. Use introductory questions like: 'What was the most challenging part of the activity?' or 'How did the use of digital tools help you better understand relative velocity?'

Reflections

1. What were the most interesting aspects you noticed about relative velocity from the activities? 2. How can the concepts of relative velocity be applied in other areas of knowledge or everyday situations? 3. What do you think could be improved in the approach or methods used during the activity?

360° Feedback

Instruct students to engage in a 360° feedback stage. Each student should receive feedback from the other group members about their contribution to the activity. Guide the class to focus on constructive and respectful aspects. Suggest they use a feedback structure like: 'I liked..., I learned from..., I suggest that...'. This helps ensure that the feedback is specific, positive, and useful for everyone's growth.
