Motion Graphs (8 of 8) Distance and Displacement in One Dimension

TL;DR

Distance is how far, while displacement is change in position with direction, making it a vector.

Transcript

all right in this video I'm gonna go over the difference between distance and displacement now most people have a pretty good working definition of distance it's just how far something has gone but most people don't really know what a good working definition for displacement is so here's a here's a diagram this is a very common diagram that you see...

Key Insights

• 🧘 Distance is the total ground covered by an object, while displacement is the change in position with direction, making it a vector.
• 🧘 Displacement is calculated as final position minus initial position, focusing on the starting and ending points.
• 💄 Displacement includes direction, making it different from distance, which is scalar and only magnitude.
• 🤘 The sign in displacement indicates direction, with positive meaning one direction and negative meaning another.
• 😥 Distance considers the entire path traveled, while displacement only focuses on the start and end points.
• ❓ The concept of distance vs. displacement is crucial in understanding motion in physics.
• 🆘 Understanding the difference between distance and displacement helps in accurately representing an object's motion.

Questions & Answers

Q: What is the key difference between distance and displacement?

Distance is the total ground covered, while displacement is the change in position with direction included. Distance is scalar, while displacement is a vector.

Q: How is displacement calculated?

Displacement is calculated as final position minus initial position. It only considers the starting and ending points, regardless of the path taken between them.

Q: Why is displacement considered a vector?

Displacement is a vector because it includes both magnitude (change in position) and direction (from start to end). This makes it different from distance, which is simply the total ground covered.

Q: Can distance and displacement values be the same?

Distance and displacement can have the same magnitude but differ in direction. Displacement accounts for direction, while distance does not, leading to potential differences even with similar values.

Summary & Key Takeaways

• Distance is the total ground covered by an object, while displacement is the change in position from start to end.

• Distance is a scalar, just magnitude, while displacement is a vector, magnitude with direction included.

• Displacement is calculated as final position minus initial position, regardless of the path taken.
