Tipping is absolutely expected in the United States. Service providers in the US are often paid below minimum wage and rely on tips as a significant source of their income. You may adjust the amount you tip based on the quality of service you receive, but it is highly recommended to always leave something, even if the service was poor. Tipping with either cash or a credit card is acceptable.
Restaurant receipts will often have a line at the bottom where you can include a tip if you paid with a credit card. If you're tipping in cash, leaving it on the table is customary. Some counter-service businesses will have tip jars at the front counter. Tips may be retained by individual employees, divided among servers, and/or divided among servers and cooks, regardless of whether you tipped with cash or a credit card.
