Ok lets examine your problem. Your pictures are too blury. if your camera is capturing your picture 1second, and if during that 1 second yor subcet moves, that move is going to captured by camera, and your subject is going yo be blured. Logicly, if you don't want this effect, you need to increase your shutter speed. So lets set our shutter speed to 1/50 which is 50-th of the second. If your subject now moves, it has to be very quickly because your camera is picturing only 50-th part of second. So if you increase your shutter speed to 1/1000 that would be 1000th part of second, so your camera will be very fast and it would freeze your subject.
But what is consequence of this. If you increase shutter speed, the less light is getting into your camera, and your picture might be dark. If this is your case, then follow the text. You still want to keep subject frrezed, so you have to keep you shutter speed very high. But how to get more light to camera whithout changing the shutter speed. Simle, expand the "gate" through light is comming in the camera. Your gate is your camera objective, and the gate is called aperture. If you open your gate as much as you can, you will get much light into camera which is exactly our aim. Aperture value is displayed as 2.0f or similar. If you set smaller numbers, then your gate/aperture will be wide open, and vice versa.
But what for example you want freeze your subject, you wide open your gate/aperture, and your pictures are still getting dark (if your picture is dark, then it is called under exposed). You can't decrease your shutter speed, because it will blur your subject. You can't open your gate/aperture more because it is wide opened. What to do? Here your ISO settings comes in game. Increasing your ISO, your camera is going to be more sensitive to light, and this is exactly what we wan't.
NOTE: Don't increase your ISO too high, it will cause grainy effect on your picture, but I suggest you to try it. Grainy effect is lots of white spots on your picture, and it sometimes can be very frustrating.
So, let's repeat all together: Shutter speed, Aperture and ISO are the first things you should read about. The more you know about them, and control them, you are better photographer.
Please, make sure you are not using zoom while you are testing my post with your camera. Your camera has great optical zoom, and it is another parameter in my story which I didn't described. First learn without using zoom, then, when you understand Shutter speed, Aperture and ISO try using zoom and see your results.
I hope I helped you :)
Also, I suggest you to start watching this videos, because you can learn a lot.
