To Do
Watch this video from Khan Academy https://www.khanacademy.org/science/physics/one-dimensional-motion/displacement-velocity-time/v/introduction-to-vectors-and-scalars
How does this video help you understand the difference between distance and displacement? Describe the differences between vectors and scalars using physical quantities as examples.
- It explains that distance is a vector and direction is important, whereas displacement is a scalar and it has no direction attached to it.
- It explains that distance is a scalar and direction is important, whereas displacement is a vector and it has no direction attached to it.
- It explains that distance is a scalar and it has no direction attached to it, whereas displacement is a vector and direction is important.
- It explains that both distance and displacement are scalar and no directions are attached to them.
