Ican't find the answer for number 9/10 pleas

(10)an object  will continue  to travel at a constant speed unless acted by an unbalanced  force  according to newtons second law every force acted on a body has a equal and opposite reaction so the speed and the direction of the object will change.

(9) balanced force (i think so )

hope this is what you needed the 10th one is for understanding you can shorten it after reading and i think what i have written is not wrong :P:P:P;p:P:):):):D=) for the ninth one i am not sure but i think so :P:)=)

It should be : balance forces
