Frame dragging is a theory which says that space is elastic, and particles in it will exchange energy with it. In the scientific world, elastic means that when you apply a certain amount of force to an object (which will cause it to bend) and then remove the force, the object will return to its original shape and energy state.
A Frame is a combination of the L2 header and the Data being carried A Packet is a combination of the L3 header and the Data being carried. In either case, the Data being carried is the payload of the Frame/Packet. This animation will help illustrate the differences: At any point in the animation, the DATA is the Payload for the respective layer (Segment, Packet, Frame). Within the Payload of the Segment is the application data put together by the application layers. Within the Payload of the Packet is the L4 header (TCP, in the animation's case), as well as the application data. Within the Payload of the Frame is the L3 header (IP, in the animation's case), the L4 header (TCP), as well as the application data
