Question

An ant starts at x = 20 cm on a piece of graph paper and walks along the x axis to x = -20 cm. It then turns around and walks back to -10 cm. What is the ant's displacement and total distance covered?​

Answer 1

Answer:

distance = 50 cm

displacement = 30 cm

Explanation:

• displacement = it is a vector which started from starting point of the motion and headed towards end point of the motion.
• distance = this is the length of path travelled during the motion.

1. distance = 20 + 20 + 10 = 50 cm
2. displacement = 20 + 10 = 30 cm

Answer 2

Given:

An ant starts at x = 20 cm on a piece of graph paper and walks along the x axis to x = -20 cm. It then turns around and walks back to -10 cm.

To find:

Distance and Displacement of ant ?

Calculation:

• Distance is the total path length traversed by an object.

So, distance = 20 + 20 + 10 = 50 cm.

• However, displacement is the shortest length between starting and stopping point of object.

• So, when ant starts from 20 cm and goes to -20 cm , then it's initial displacement will be 20+20 = 40 cm.

• Then after the turning , it goes to -10 cm so, the net final displacement will be 40-10 = 30cm.
