Go to Settings, Applications directory. Find the application you want to move. Click "Move to SD card" in the storage tab. Android 5.0's memory card support is less comprehensive than its successor Android versions. So the number of applications you can move to the memory card is lower. Also, not the whole application, only some parts of it are moved to the memory card. Finally, let's make a reminder about the steps. If it turns gray when you press the "Move to SD card" option, it means the process has started. Do not interfere.
