Bearing rocks, enter with some force (5,2)
I believe the answer is:
barge in
'enter with some force' is the definition.
(to barge in is to forcibly enter a place)
'bearing rocks' is the wordplay.
'rocks' indicates an anagram.
'bearing' with letters rearranged gives 'BARGE IN'.
(Other definitions for barge in that I've seen before include "Rudely interrupt" , "Unexpectedly enter" , "Enter uninvited" , "Rudely intrude" , "Gate-crash, break into a conversation" .)
