Distance is a scalar and displacement is a vector
Explanation:
Distance and displacement are two different quantities. Let's review them in detail:
- Distance is a scalar quantity (only a number followed by unit). Distance represents the total length of the path covered by an object during its motion. Therefore, it does not take into account the direction of motion, in its calculation.
- Displacement is a vector quantity, so it has a magnitude, a unit and a direction. Displacement is a vector connecting the initial position to the final position of the motion of an object. Therefore, in its calculation, the direction of motion must be taken into account.
Let's see an example in order to understand distance and displacement better.
Imagine a person moving 5 meters forward and then 2 meters backward. In this case:
- The distance covered by the man is just the total lenght of the path covered, therefore: 5 + 2 = 7 meters
- The displacement of the man is the distance between the initial and final position. Since the man moved 5 m forward and 2 m backward, his final position is 3 meters forward, therefore the displacement is 3 m in the forward direction.

The type of investigation is she is conducting by determining the period in which it is from is referred to as the geologic age.
<h3>What is Geologic age?</h3>
This is defined as the time period in which the fossil was present on the earth and can be done using various methods such as radiometric dating methods etc. The age gotten will help scientists to ascertain different information about the organism in this context.
Fossil on the other hand which is the remains of organisms preserved in the earth crust can be studied to find out the differences in the features of organisms and how they were able to adapt to the changing environmental conditions.
