If an object is less dense than water, or if it floats on water, it displaces the same weight of water equal to the weight of the object. If the object sinks in water, it displaces a volume of water equal to the volume of the object. This is known as the Archimedes principle

An object is lighter in water compared to in air because water exerts an upward buoyant force on the object that partially counteracts the downward force of gravity. This buoyant force makes the object feel lighter when submerged in water.

Is there any material that becomes heavier when submerged in water and lighter when it is taken out?

A porous object absorb water and is heavier. In air the water is evaporated and the object become lighter.


When an object is in water is it heavier or lighter?

When an object is in water, it may appear lighter because of the buoyant force acting on it. The buoyant force counteracts the weight of the object, making it feel lighter in water compared to in air.


Does a heavier object or a lighter object experience a greater gravitatoinal force?

the heavier object


What heavier object sinks but the lighter object floats but the heavier object can be a thousand times larger than the lighter object?

Not a clue. Please Tell Me The Answer ?? :)


Would an object be heavier or lighter on the Sun?

The object is actually lighter on the Sun


Does a heavier object or a lighter object experience a greater gravitational force?

A heavier object experiences a greater gravitational force than a lighter object, as the force of gravity is directly proportional to the mass of an object.


Does an object become heavier when placed in water?

No. It becomes lighter as the water exerts an upthrust on the object according to the archmides' principle. Thus the reaction force ( or the weight ) of an object becomes less.


Is there more gravitational potential energy in heavier object or lighter object?

There is more gravitational potential energy in a heavier object compared to a lighter object. This is because gravitational potential energy is directly proportional to an object's mass and height. Therefore, the heavier object with more mass would have a greater gravitational potential energy when raised to the same height as the lighter object.


What is Compares is an objects density to the density of water?

Specific gravity is a measurement that compares the density of an object to the density of water. It tells you how much heavier or lighter an object is compared to an equal volume of water.


Why is the heavier object harder to accelerate than the lighter one?

Inertia


Does a heavier object or a lighter object experience a greater gravational force?

A heavier object experiences a greater gravitational force than a lighter object due to its larger mass. Gravity is directly proportional to mass; the greater the mass, the greater the gravitational force.


How does weight factor in when determining buoyancy?

The lighter a certain object is, the more likely it is to float, if the object is heavier, the object will sink.
