Question

Ben helped his parents load boxes and furniture onto the moving truck. He easily carried several boxes out of the house and up a ramp into the truck. Then loaded small pieces of furniture by pushing them up the ramp. Finally, Ben tried to move the refrigerator. He pushed and pushed, but it did not move. Why?

Answer 1

because the refrigerator was too heavy for Ben.

Answer 2

Answer:

Force required to move the refrigerator was much higher than the force applied by Ben

Explanation:

Refrigerator being a heavy equipment than the small boxes, require higher force in order to move up on a moving truck.

Ben might have used his entire energy to refrigerator but being a heavy object it requires additional force from another person or by some lifting equipment.

Thus, tough Ben pushed and pushed again but the refrigerator did not moved.
