The shopper lifts each bag at the same speed. Which bag is lifted with a larger force?

 - a bag holding 6 pounds of food
 - a bag holding 3 pounds of food
Look for the shopping bag that is heavier.
A shopping bag holding 6 pounds of food is heavier than a shopping bag holding 3 pounds of food. So, the bag holding 6 pounds needs a larger force to start moving upward at the same speed as the other bag.
