The mom and dad push the strollers at the same speed. Which stroller is pushed with a larger force?
a stroller with kid that weighs 22 pounds a stroller with kid that weighs 28 pounds
A mom, a dad, and two kids are going for a walk. The mom and the dad each push one of the kids in a stroller. The strollers are the same. But the kids are different sizes.
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 stroller that is heavier.
A stroller holding a kid that weighs 28 pounds is heavier than a stroller holding a kid that weighs 22 pounds. So, the stroller holding the kid that weighs 28 pounds needs to be pushed with a larger force to start moving forward at the same speed as the other other stroller.
