-- Change its mass and weight.
Fill any holes inside the object, or carve out new holes inside it.
-- Change its volume.
Form it into a new shape, like a cup, that displaces much more water
than the compact lump does.

What is the effect of density on the buoyancy of an object?
greater density tends to less buoyancy
What causes the buoyancy to increase or decrease?
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
What is buoyancy and how is it affected by density?
Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.
In order for an object to have neutral buoyancy what would the relationship between the density of the object and the density of the fluid have to be?
They have to be the same.
How does the liquid density affects the buoyancy of objects placed in the liquid?
Yea
How does object volume affect buoyancy?
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
What is the effect of density on the buoyancy of an object?
greater density tends to less buoyancy
How does density affect buoyancy of an object?
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.

When does an object have positive buoyancy?
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.

How does the liquid density affects the buoyancy of objects placed in the liquid?
Yea
Is buoyancy and density the same?
An object with greater density than the liquid it is placed will tend to sink
What is another word to describe an object with neutral buoyancy?
It is average density.
In terms of buoyancy how does a life jacket save your life?
A life jacket is also known as a floatation or buoyancy aid - it acts to increase your buoyancy. So what do we mean by this? Well, buoyancy can be described simply as how easily an object will float in a fluid (or gas), where the more buoyant the object the better it will float. Buoyancy is related to the density of an object which is in turn related to the amount of mass a given object has relative to it's volume. As the density of an object gets larger compared to the density of the fluid it is floating in, its buoyancy will decrease and it will become less able to float. As the density of the object becomes larger than the density of the fluid it is floating in, it will sink. Now that we understand buoyancy, we can explain how a life jacket works. A life jacket is mainly filled with gas which has a very low mass. As such when worn by a person, it acts to significantly increase their volume for only a very small increase in their mass. This means that they have a lower density than normal which increases their buoyancy and helps them to float.
The buoyancy of an object can be changed by changing the object's average density true or false?
The upthrust depends on the volume of object if volume is more the liquid displaced will be more and the force per unit area will increase and density is equal to mass per unit volume so by density the buoyancy.
