Narrative: Immediately after the 10;000 feet chimes; the C Flight Attendant (FA) and I collected garbage. Upon finishing that task; I washed my hands in the lavatory. As I was leaving the lavatory; my watch caught on the lavatory's doorframe; breaking a piece off my watch. I used a flashlight to find the pieces; got out an extra Ziploc baggie; and put all of the pieces of my watch in it. I then put the baggie and watch pieces in my flight bag and got out/put on my extra watch. At that point; I realized all we had done after the 10;000 feet chimes and realized I had lost track of time. The C FA had moved forward securing the cabin and getting into her jumpseat. I tried to see how close we were to the ground by looking out the window. Due to the way the sun was shining; I couldn't see anything to get my bearings. I quickly closed and secured the few remaining galley compartments and checked the brakes on the carts. (I obviously missed the red safety levers on two carts as you will see below.)Thinking we must be close to the ground; I hurried to my jumpseat; all the while checking out the window as I was buckling in. I was able to completely and securely buckle into the jumpseat before landing. As soon as we landed; though; and the plane was quickly slowing; a cart rolled out of place very fast; headed straight down the aisle. It all happened so fast; at first I considered trying to catch it; but immediately realized the force would probably break my arm; so I pulled it back. [Another] cart also rolled out; but caught on the corner of the galley wall; and I was able to put out my leg and keep it from turning or moving further.As soon as the major force of landing/slowing down was over; I got out of my jumpseat to check on the safety of the passengers in the last row of seats and attempt to secure the carts as quickly as possible. This means that I was out of my jumpseat during taxi to the station. We had passengers in seats A; D; and F of the last row of the plane. I was most worried about the passenger in D. The cart had hit the back of seat C and was sitting at a diagonal in the aisle. It did not hit seat D that had a passenger in it. All three ladies were fine; they expressed concern/worry for me. After checking the safety of the passengers verbally; I quickly re-stowed both carts before the plane was stopped at the station. Once again I checked on the passengers in the last row. They were fine. I then carried on with my duties regarding door opening procedures.I feel like I should not have taken the time to look for and gather the broken pieces of my watch. Doing that; and taking the time to put it away in my flight bag caused me to lose track of time prior to landing. Because I lost track of time; I was concerned for my safety during landing and didn't carefully check the compartments/carts.I feel like I should have made sure the carts and compartments were secure before washing my hands; to begin with. Once my watch broke; during that critical time of the flight; I should have left the broken pieces on the floor and attempted to deal with it after landing. I am usually so careful; double and triple checking brakes and latches. Today I just got distracted and lost track of time/position in regards to landing. Also; I do feel like there isn't always enough time to collect garbage and secure the cabin (galley; lavatories; seatbacks; tray tables; passenger bags) after the 10;000 feet chimes. I usually try to start the final garbage pickup prior to 10;000 feet; today I didn't do that. Perhaps that was why I got so worried about where we were in the landing sequence.




Synopsis: B737 Flight Attendant reported an inflight distraction was a factor in her not properly securing the galley carts; several of which rolled down the aisle after landing.
