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].

.

The error in question 4 is that the units for acceleration are incorrect. Acceleration is not measured in meters per second (m/sec), but rather in meters per second squared (m/sec^2). Additionally, the direction should not be included in the units, as acceleration is a scalar quantity. Therefore, the correct answer would be b) 5 m/sec^2. It is important to pay attention to units and their proper usage in physics, as they can greatly impact the accuracy of calculations.
