How to determine the displacement of a particle from a table

The video tutorial explains how to calculate displacement by subtracting the initial position from the starting position. It provides an example calculation and discusses how to present answers in different formats, such as for free-response questions (FRQ) and multiple-choice questions. The importance of simplification and the use of units in answers are also highlighted.

What is the initial step in calculating displacement?

• Add the final position to the initial position

• Subtract the starting position from the initial position

• Multiply the starting position by the initial position

• Divide the final position by the initial position

What is the displacement if the initial position is 0 and the final position is 40?

• 40

• 20

• 80

• 0

In a free-response question, is it necessary to simplify your answer?

• Simplification is optional but recommended

• Yes, always simplify

• Only if the question specifies

• No, simplification is not required

Why might simplification be important in multiple-choice questions?

• Because unsimplified forms may not be listed as options

• Because unsimplified forms are always correct

• Because simplification is never required

• Because it makes the question harder

Which of the following is a reason to simplify an answer in a multiple-choice test?

• To confuse the test-taker

• To ensure it matches one of the given options

• To make the question more complex

• To make the answer longer
