I need help figuring out adjusting entries for amortization expense/accumulated amortization and interest expense/interest payable for the two following scenarios. I am unclear on amortization and which constitutes amortization

For year end December 31, 2017

6% interest note payable made on January 3, 2017 and is due on February 1, 2019

5-year loan was made on June 1, 2017. Terms are 7.5% annual rate, interest only until due date.
