Get some work done

Wednesday 24 January 2018

Me: Helene, why aren´t you doing any work?

Helene: Because there is no displacement in the direction of the force.

Well it didn´t quite go like that but I never let the truth get in the way of a good story. I´ve been trying to emphasis how important it is that they have good understanding of concepts like work and energy. The problem is that these words have many uses.

Nasty bit of work - Being moved by a force to somewhere you don´t like
Worked over - pushed over by a force
Homework - moved by a force at home

Energy bar - the ability to do work while drinking
Energy crisis - the inability to do work
