Whats the grinding noise after i hit pothole

What is your question?

I hit a big pothole,car bottomed out real bad,i got out and checked didnt see any fluid spills and all tires were still inflated. Drove home about 10 miles, car stopped 3 times on the way there. No oil lights, check engine, no warning lights at all came on the dash. About a block away from home I started hearing a grinding noise coming from under the hood. Once home, i parked got out, looked under the car again and saw a lot of moisture ,most of it at the passenger side of the undercarriage. Still no flat tires. I tried to start the car but it didn't do anything. Decided to give it a jump and eventually it cranked, still no warning lights on the dash but the loud grinding noise was still there. Car shut off after about 5 minutes. It keeps doing this, i give it a jump, it starts, then after about 5 minutes it shuts off. Still no warning light's on the dash, temperature gauge never moved and no smoke. Broke something i assume by the amount of moisture on undercarriage but what?

What makes this problem better or worse?

It got worse during the drive home haven't driven it since
