Which of the following correctly describes the relationship between the average resultant force acting on an object, the change in momentum of the object, and the time interval during which the force acts?
force=change in momentumtime\text{force} = \frac{\text{change in momentum}}{\text{time}}force=timechange in momentum
force=change in momentum×time\text{force} = \text{change in momentum} \times \text{time}force=change in momentum×time
force=timechange in momentum\text{force} = \frac{\text{time}}{\text{change in momentum}}force=change in momentumtime
force=change in momentum×mass\text{force} = \text{change in momentum} \times \text{mass}force=change in momentum×mass
