Brain of Britain

BBC Radio 4 has a general knowledge quiz-show modestly titled 'Brain of Britain'. The 2016 final of 'Brain of Britain' was broadcast this week. The four contestants were:

John, a dentist from Southampton.
Ian, a software developer from North Worcestershire.
Mike, a driver from Brechin.
Jane, a teacher and writer from Edinburgh.

After 7 mins, quiz-master Russell Davies poses the following question:

"In science, what name is given to the product of the mass of a particle and its velocity?"

Bit of a tricky one, eh? Science question. Still, at least it's an elementary science question, the type of question that anyone who didn't leave school at the age of 12 should be able to answer, surely?

In fact, this simple question elicited the following responses, in turn, from the contestants. And remember, these are the four finalists on a show entitled 'Brain of Britain':

John: "vector?"
Russell Davies: "No."
Ian: "acceleration."
Russell Davies: "Not that either, no"
Mike: "Force?"
Russell Davies: "No-o."
Jane: "Is it speed?"
Russell Davies: "It's not speed, it's momentum."

Still, it was Radio 4, so a science question does go somewhat outside the usual diet of politics, GCSE economics, and the arts.
