Question

Olivia places her pet frog on a line to observe the frog’s motion. The line is divided into sections that measure 1 centimeter each. The frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backward, and then 12 centimeters backward.

What is the frog’s displacement?

Answer 1

The frog's displacement would be 0, A.

Explanation:

Given: The frog begins at 0, moves 18 centimeters forward, moves 6 centimeters backward, and then 12 centimeters backward.

12+ 6 is 18, and if the frog moves back 18 (Which is the same distance is moved forward) then the frog did not move at all.

Displacement is the distance something or someone moved.

Answer 2

Answer: 0

Explanation: Displacement is how far something or someone is from the starting point, in this case, the frog, so it moves 18F then 6B then 12B, so 0+18-6-12=0.

Hope this helps! :)
