Captain Granit shook his head. "Water fights back. That's and drag ."

"That's how much energy we need to give the chest to lift it," she said. "Can't we just pull it straight up?" Milo asked. np fysik åk 9

Alva’s eyes lit up. "Wait, this is real physics. Let me think." Captain Granit shook his head

Captain Granit smiled. "Good. Let’s start with , young navigator." 1. Energy – The invisible currency "The chest at the bottom has potential energy because it’s deep," the captain explained. "But we need to give it kinetic energy to move it up." "Can't we just pull it straight up

Slowly, the chest rose. When it broke the surface, Milo gasped. "It worked!"

"I know exactly where a sunken treasure chest is," he said, pointing to a rusty anchor. "But the winch is broken. We need to lift the chest from the seabed. It's 50 meters down and weighs 200 kg."

Milo groaned. "That sounds like a physics problem. I'm out."
