Identify the following quantities as scalar or vectors: the speed of a snail, the time it takes to run a mile, and the free-fall acceleration.
- A Vector, scalar, scalar
- B Scalar, scalar, vector
- C Vector, scalar, vector
- D Scalar, vector, vector
That's Correct!
It's Wrong!
The speed of a snail is a scalar quantity because it only has magnitude and no direction. The time it takes to run a mile is also a scalar quantity as it only represents a duration and has no direction. On the other hand, free-fall acceleration is a vector quantity as it has both magnitude (9.8 m/s²) and direction (downwards towards the center of the Earth).
