Suspension

There is no way to tell over a computer. Someone is going to have to perform an inspection. A tire and alignment shop is the best place to go. Some possibilities include a deteriorated outer anti-sway bar bushing, a sloppy strut or rusted upper strut mount. Those are not serious. A worn ball joint can cause a knocking noise that you don't want to neglect. If it separates, the bottom of the wheel will flop out and you'll lose control. Loose brake pads or calipers will cause a metallic clunking sound that will stop when you hold light pressure on the brake pedal.
