Moving water, like that of a river, carries sediment as it moves along its bed. the faster the water flows, the more sediment that is carried and the larger the sediment particles. as the river slows down, the heavier particles of the load will settle out. how can you explain the particle movement based on newton's laws of motion? a) an object remains at rest until a force acts on it. b) for every action there is an equal and opposite reaction. c) the greater the force of the water, the faster the particle accelerates. d) the water and the particle exert a gravitational attractive force on each other.
