Bill and bob are carrying loads of trash to the dump. they are walking down the sidewalk, side by side but bob begins to lag behind bill. explain what's happening using one of newton's laws of motion.

Newton’s first law states that “a body at rest will stay at rest, and a body in motion will stay in motion, unless it is acted upon by an external force” to explain this is because bob is lugging a lot of trash it is acting upon his body which is in motion and causing his body to slow down, thus the lagging of bob behind bill
