If two objects collide with each other, then The sum of their momentums after the collision is equal to the sum of their momentums before the collision O They both lose momentum at the moment of impact The object with greater mass always has greater momentum The momentum before the collision is always greater than the total momentum after the collision How does wearing a seatbelt reduce your chance of getting hurt during an accident? Seatbelts increase momentum before collision Seatbelts reduce momentum during a collision Seatbelts decrease the time it takes a person to stop moving Seatbelts cause friction
