Why the ships can float on the sea but a small stone sinks in water?
If you dropped a small stone into the water, it would sink immediately. But because of its body design, which contains a lot of air, it displaces (pushes aside) enough water so that the buoyancy force is equal to its gravity force. That is why a ship floats.
Does balsa wood float in water?
If you take pieces of different types of wood (all the same size), you’ll notice that some of the wood is heavier than other. This is called density. The heavier wood (like oak) is more dense than the lighter wood (like balsa). If you put the pieces of wood in a tub of water, they’ll float.
What force works in the opposite direction of buoyancy floating )?
Pressure variations in a fluid are typically caused by gravity (sinceP = P0 + ρgh), but in general buoyant forces act opposite the direction of the frame of reference acceleration.

Can you ride on a cargo ship?
Freighter Travel is Popular You can travel from one port to another or around the world by freighter. It’s relatively inexpensive (compared to other cruise ships) and easy to do as more and more freighter companies come on board to offer passenger service.
Is traveling by cargo ship cheaper than flying?
It’s cheaper (and cooler) than flying. Cargo cruises cost between $65 and $125 per day, which includes lodging and three meals a day. Voyages usually last between 40 and 50 days, but some people opt for segmented trips that last a few weeks, leaving on a boat, disembarking at a port, and returning home by plane.
