Main Question or Discussion Point
There are two disks of the same size and mass. A 5N force acts through the center of the first and another 5N force acts through the bottom of the other. The forces both point to the right. According to what I have learned, the linear momentum of both objects will be the same, but the second one will have angular momentum. The second object must then have more energy than the first. How can two equal forces have different energy outputs?
