If you have no idea what's wrong then you probably would not be able to fix it either. If a brand new bike then contact the seller for help, see if there's a bike co-op in your town, or go to a bike shop for diagnosis.

some bikes are like that. The rear wheel only spins with the pedals. Try pedaling backwards and see if the wheel goes back. If it does then that is normal.

Local bike shop determined that both wheels were defective. I took the junk back to Walmart and got a refund... PROBLEM SOLVED!!

Something to remember. Bicycle manufacturers only construct the frame and fork. All the other components are produced by other companies such as SRAM and Shimano. Trek produces other parts besides the frame and fork.
Any parts you need are available at your local bicycle dealer.

It sounds as though the chain is too tight. Check to see when it is "freewheeled" if the chain gets tighter. Generally this will happen because the chain ring (front sprocket) was not perfectly aligned with the "spider" (thing it bolts to). You can loosen the chain a little and see if this helps. Be careful because you don't want it so loose the it comes off while riding. What I usually do is adjust the tension of the chain with the sprocket in the tight spot. Kind of tight but without the "grinding" feeling.
Good luck.
