Question

1. sep construct explanations rather than push a heavy box from one room to another, a worker chooses to place the box on a wheeled cart. in terms of friction, explain why moving the box on the wheeled cart is easier than pushing.

Explanation:

When pushing a heavy box directly, there is sliding friction between the box and the floor. Sliding friction is relatively large as the surfaces slide over each other. When the box is placed on a wheeled cart, the friction changes to rolling friction. Rolling friction is much smaller because the wheels roll rather than slide. With less friction to overcome, it is easier to move the box on the wheeled cart.

Answer:

Moving the box on the wheeled cart is easier because rolling friction is less than sliding friction.
