The force of gravity acting on an object

Weight

The amount of matter that makes up an object on substance

Mass

The amount of space an object or substance takes up

Volume

Earth

Where is the gravity more storage moon or earth

Fill a can untill it over flows wait till the flowing stops

Place the object into the can slowly

Collect and measure the volume of the displaced water

Whats the volume of an irregular shaped solid

Density is a measure of the mass per unit volume of a substance

Whats is density

The mass of the particles

How tightly the particles are packed

What is 2 things the density depends on

are often denser the liquids

Since particles of solids are usually closer toghter then the particles of a liquid, solids …

The space between gas particles are larger than those in solids and liquids, which means that there are considerably fewer particles in a given volume of gas

Why are gases not as dense as liquids and solids

False

Ture of False. Density is not affected by the type of particles of a substance

A property that makes a particular substance distinct from others

What is the characteristic property

Air, carbon monoxide, gasoline, distilled water, and sea water

What fluidsn are less dense than water

Pure gold

What is 2 samples of ____________ will always have the same density

Pure water is most dense at 4 deggers

What temperature is pure water the most dense at

Air, carbon monoxide, gasoline,distilled water and sea water

what are all the fluids that are more dense the water

Buoyancy is an upward force created by fluid that opposes the weight of an object

What is Bouyancy

An object is positively Bouyant if it density is less than the fluid it is in

What is positively Bouyant

An oject is negatively buoyant if it density is more than the fluid it is in

What is Negatively Buoyant

An object that dosen’'t sink or float it remains balanced at the same level of fluid

What is Neutrally Bouyant

More density = sinking

Less density = floating

How dose density affect the buoyancy of an object

Is that the bouyang force ( upword force) is equal to the weight of the displaced water

What is the Archimedes principle

Sink

if less water is displaced than the object will…

float

if more water is displaced than the object will…
