• Upthrust

Why do heavy objects like ships float on water?

• They have a small surface area

• They are made of light materials

• They displace a lot of water

• They contain a lot of water

What happens to an object if its weight is greater than the upthrust?

• It floats

• It sinks

• It remains suspended

• It evaporates

Which type of water is denser, making it easier for objects to float in it?

What force pushes you upwards when floating on water?

• Upthrust

• Magnetism

• Friction

• Gravity

What happens to a ship if it is overloaded with cargo?

• It floats higher

• It sinks

• It becomes more buoyant

• It displaces less water

What is the relationship between an object's weight and the upthrust for it to float?

• Weight is less than or equal to upthrust

• Weight is greater than upthrust

• Weight is equal to gravity

• Weight is less than gravity

What is the main reason objects float on water?

• They are heavier than water

• They are less dense than water

• They are more dense than water

• They are the same density as water

What is the effect of salt in water on buoyancy?
