What is the difference between a car loan and car lease?

My mom wants to return her vehicle and she says it’s out on a loan. My parents never bought a car, and now that my father passed away, she turns to me for what to do. She wants to know if she can just go and turn it in and pick out a new one or will she have to pay more for some damage to the vehicle! Please help. Serious answers only!

What is the difference between Bankruptcy and Bankruptcy Protection that I hear in the news recently?

In recent news, companies could be forced to Bankruptcy. Is this the same as “companies can be forced into Bankruptcy Protection”?

I thought Bankruptcy protection is “PROTECTION” against Bankruptcy?
