Physics Teachers Using km/h Instead of m/s To Waste Students Time

physics teachers carefully putting km/h instead of m/s to waste time of the students

This is a single panel reaction meme. At the top, text reads 'physics teachers carefully putting km/h instead of m/s to waste time of the students'. Below the text is a screenshot of the fictional character Walter White (Heisenberg) from the TV series Breaking Bad, wearing a yellow hazmat suit and looking focused as he carefully dispenses liquid from a pipette into test tubes. The joke is relatable to secondary and post-secondary physics students: while the SI standard unit for speed is meters per second (m/s), physics teachers often list speeds in kilometers per hour (km/h) in assignment and test problems, forcing students to complete extra unit conversion steps that add time to problem solving. The deliberate, scheming expression of Walter White frames this choice as an intentionally devious act by teachers to make students spend more time on work. The original title of the meme asks 'Is it really necessary?', which the meme humorously answers as 'no, it is only done to waste student time', though unit conversion is technically a required core skill for physics.

This meme was originally shared on Reddit as a user-created post with the title 'Is it really necessary?'. It uses a widely circulated meme template taken from a scene in the American TV series Breaking Bad, where Walter White works in an underground meth lab. This template is commonly used online to depict someone performing a small, intentional, slightly mischievous or scheming action with great care.
