How Does Your Boat Float?

Front

What can increase the density of a ship?

Back

Filling it with cargo or people.

Front

When will an object float in water?

Back

When its weight is less than the weight of the water it displaces.

Front

What is buoyancy?

Back

The force exerted by surrounding fluids.

Front

What are Plimsoll lines on cargo ships used for?

Back

To show when the ship is full enough.

Front

What happens when an object sinks too far in water?

Back

It will fill with water and sink.

Front

What is density?

Back

The mass of an object per unit of volume.

Front

What is the principle of displacement?

Back

An object will displace a volume of water equal to its submerged volume.

Front

How does shape affect buoyancy?

Back

The shape of an object can affect how much water it displaces, influencing its ability to float.

Front

What is the relationship between weight and buoyancy?

Back

An object will float if its weight is less than the buoyant force acting on it.

Front

What is the role of air in a ship's buoyancy?

Back

Air inside a ship reduces its overall density, helping it to float.
