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 8 pounds of food
A shopper is buying food at the store. He fills two shopping bags. The shopping bags are the same size and shape.
A force is a push or a pull.
A force can make an object start moving or stop an object that is moving. A force can also make an object speed up, slow down, or change direction.
Forces can be different sizes.
Think about trying to move a heavy object and a light object. Imagine you want to move them at the same speed. You will need to use a larger force to move the heavy object.
Look for the shopping bag that is heavier.
A shopping bag holding 8 pounds of food is heavier than a shopping bag holding 6 pounds of food. So, the bag holding 8 pounds needs a larger force to start moving upward at the same speed as the other bag.
