Broadcast is used when the destination address is a broadast address.
Flooding is generally used to refer to when a packet is sent out of all ports on a switch because the switch does not have an entry in the mac-address table for that destination mac-address. So unlike broadcast the packet may have a unicast destination address but it is still sent out of all ports.
You may find that some books etc. use the terms interchangeably so it can get a bit confusing.

Adding to jon's reply:
a layer-2 broadcast means a frame with destination mac of FFFF.FFFF.FFFF, when a switch recieves such frames, if forward it out all ports except the source the frames was recieved on.
