Understand the Problem

The question asks for the calculations of distance and displacement based on Athena the cat's movements in a linear path. It involves understanding the concepts of total distance traveled and the net change in position (displacement) from her starting point to her ending point. The user must choose options for both measures from a provided list and explain the differences between distance and displacement.

Answer

Distance: 7 feet; Displacement: 1 foot left.
Answer for screen readers

Distance: 7 feet
Displacement: 1 foot left

Steps to Solve

  1. Calculate Total Distance Travelled

First, we determine the total distance that Athena traveled. She walks 3 feet to the right and then 4 feet to the left:
Total distance = 3 feet + 4 feet = 7 feet.

  1. Calculate Displacement

Next, we calculate the displacement, which is the net change in position from the starting point. Athena moves 3 feet to the right and then 4 feet to the left. This can be calculated as:
Displacement = Distance to the right - Distance to the left
Displacement = 3 feet - 4 feet = -1 foot.

  1. Interpret the Results

The distance is a total travel measure, while displacement indicates the position relative to the starting point.
Thus:

  • Distance: 7 feet
  • Displacement: 1 foot left (the negative sign indicates the direction to the left).

Distance: 7 feet
Displacement: 1 foot left

More Information

In motion, distance measures the total path taken, while displacement considers direction and the shortest path from start to finish. Athena walked a total of 7 feet, but due to her leftward movement, her effective displacement is 1 foot left.

Tips

  • Confusing distance with displacement: Distance is the total length traveled, while displacement needs direction considered.
  • Forgetting to account for direction when calculating displacement.
