Interest Rate Futures vs Bond Futures minute, please, someone, reading, interest

Howd

In CFAI book 4 Page 115, why is this section titled "Interest Rate Futures" when "Bond Futures" are being discussed? Risk Management readings deal with Long interest rate futures that have gains when rates rise, but here the reading talks about gain when rates fall.

Might as well throw in FRA, please clarify how they differ from Interest Rate Futures?


My brain is fried, and I am disgusted at myself for dealing with this last minute, but can someone please post payoff equations for Interest Rate Futures and Bond Futures to disambiguate them for me?
