The donkeys move the carts at the same speed. Which cart is pulled with a larger force?
a cart holding 45 pounds a cart holding 87 pounds
Two donkeys pull carts from the farmhouse to the yard. The carts are the same. Each cart is holding different tools.
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 cart that is heavier.
A cart holding 87 pounds is heavier than a cart holding 45 pounds. So, the cart holding 87 pounds needs a larger force to start moving at the same speed as the other cart.
