Buoyancy

Front

What is buoyancy?

Back

Buoyancy is the upward force exerted by a fluid that opposes the weight of an object immersed in it.

Front

What is displacement in the context of buoyancy?

Back

Displacement is when an object moves water to the side, creating space for itself in the fluid.

Front

What is the density of water?

Back

1 g/ml

Front

Why do boats float?

Back

Boats float because their hollow shape leads to a low density compared to the water.

Front

What is the relationship between weight and mass?

Back

Weight and mass are not the same; mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What happens to an object with a density less than water?

Back

An object with a density less than water will float.

Front

What happens to an object with a density greater than water?

Back

An object with a density greater than water will sink.

Front

How does the shape of an object affect its buoyancy?

Back

The shape of an object can affect its buoyancy by influencing its volume and the amount of water it displaces.

Front

What is Archimedes' principle?

Back

Archimedes' principle states that the upward buoyant force on an object is equal to the weight of the fluid displaced by the object.

Front

What is the formula for density?

Back

Density = Mass / Volume
