SUMMARY

The discussion centers around an error found in the "Beginning Physics" novice quiz related to calculating acceleration. The question presents a scenario where a cyclist changes velocity from 5 m/sec [N] to 15 m/sec [N] over 4.0 seconds. The correct calculation for acceleration, which is defined as the change in velocity divided by the time taken, reveals that the answer should be 2.5 m/sec² [N], corresponding to option (a). The error was in the interpretation of the question and the answer choices provided.

PREREQUISITES
  • Understanding of basic physics concepts, specifically acceleration.
  • Familiarity with the formula for calculating acceleration: (final velocity - initial velocity) / time.
  • Knowledge of vector quantities and their directional components.
  • Basic arithmetic skills for solving equations.
NEXT STEPS
  • Review the principles of kinematics in physics.
  • Study the concept of vector quantities and their applications in physics.
  • Practice solving acceleration problems with various scenarios.
  • Explore online resources or textbooks that cover introductory physics concepts.
USEFUL FOR

This discussion is beneficial for novice physics students, educators preparing quizzes, and anyone interested in understanding the fundamentals of motion and acceleration in physics.

Near the top of this web page, there is a link to a quiz. If you take the Novice quiz called "Beginning Physics", you will find an error in question 4:

Question: A cyclist changes velocity from 5 m/sec [N] to 15 m/sec [N] in 4.0 sec. What is the value of her acceleration?

a) 2.5 m/sec
b) 5 m/sec
c) 1.5 m/sec
d) 3.5 m/sec

Can you spot it? Highlight the text below for the answer.

Highlight this
Acceleration is length per time squared. And it has a direction, in this case [N].
