Relative motion is the concept of describing how an object's position or velocity changes from the perspective of another moving object or a specific frame of reference. Motion is not absolute; it is always relative to an observer's chosen point of reference, which can be a stationary point or another moving object. For example, a person walking on a moving train is stationary relative to someone on the train but appears to be moving relative to someone standing on the ground outside the train. 💡Key concepts • Frame of reference: A coordinate system or point of view used to measure motion. The concept of relative motion is about how a change in position is measured from different frames of reference. • Relative velocity: The velocity of an object as measured by an observer in a different reference frame. This can be calculated by finding the difference between the velocities of the two objects relative to a third, common reference frame. • Vector quantities: Velocity and displacement are vector quantities, meaning they have both magnitude and direction. When calculating relative motion, these vector directions must be considered, often using vector diagrams or equations. • Example: Imagine a car moving at \(60\) mph and a person walking inside it at \(5\) mph in the opposite direction of the car's travel. The person's velocity relative to the ground is \(55\) mph, while their velocity relative to the car is \(5\) mph in the opposite direction. 💡Worksheets are provided in PDF format to further improve your understanding: • Questions Worksheet: https://drive.google.com/file/d/1FZHK2lvewIfauVNmVxQprxLvhBZfVv02/view?usp=drive_link • Answers: https://drive.google.com/file/d/1h8pFAHvhQo5qqSPsfYA9GETrdjMQg8z8/view?usp=drive_link 💡Chapters: 0:00 Reference frames and relative motion 3:45 Worked examples 🔔Don’t forget to Like, Share & Subscribe for more easy-to-follow Calculus tutorials. 🔔Subscribe: https://rumble.com/user/drofeng _______________________ ⏩Playlist Link: https://rumble.com/playlists/d3cTgspk0Ro _______________________ 💥 Follow us on Social Media 💥 🎵TikTok: https://www.tiktok.com/@drofeng?lang=en 𝕏: https://x.com/DrOfEng 🥊: https://youtube.com/@drofeng
