Worked practice questions

Once you assign a positive direction in a problem, you:

  1. Cannot change it
  2. Must reverse it
  3. Can ignore it
  4. Must double it
Show answer and solution

Correct answer: A. Cannot change it

1. Any direction can be chosen as positive. 2. But once chosen it cannot change. 3. Consistency is what matters. _Source: OpenStax College Physics for AP Courses 2e, Chapter 2, Kinematics (CC BY 4.0)._

The SI unit for time is the:

  1. Swing
  2. Second
  3. Minute
  4. Cycle
Show answer and solution

Correct answer: B. Second

1. Time is measured by comparison with a standard. 2. The SI unit is the second. 3. A pendulum swing can serve as a clock. _Source: OpenStax College Physics for AP Courses 2e, Chapter 2, Kinematics (CC BY 4.0)._

A lecture runs from 11:00 to 11:50 AM. The elapsed time is:

  1. 60 min
  2. 5 min
  3. 50 min
  4. 10 min
Show answer and solution

Correct answer: C. 50 min

1. Elapsed time is end time minus start time. 2. That gives 50 minutes. 3. A stopwatch would read 50 min at the end. _Source: OpenStax College Physics for AP Courses 2e, Chapter 2, Kinematics (CC BY 4.0)._
