This is a panning shot where the background is blurred but you can still see the object, so you follow the object with the camera and use shutter speed so you can capture a smooth panned shot
This is blurred shot to achieve a shot like this i used a shutter speed which i set the speed to 1/25 or less it also is when the object is moving for example this picture below, and you capture it and it's blury but the background is clear
