Key Points about Density/Buoyancy
100
1.0g/mL
What is the density of water?
100
DENSITY = MASS divided by VOLUME
What is the formula for density?
100
The measurement of how much mass of a substance is contained in a given volume.
What is the definition of Density?
100
Buoyant force is greater that the gravitational force.
The object floates because-----
100
Anything that causes a change in the motion of an object.
Define Force?
200
Greater than 1.0g/mL
What is the density of an object that sinks in water?
200
Mass / Density
What is the formula for volume?
200
The amount of space an object takes up.
What is the definition of Volume?
200
Mr. Humpty (egg) floated because density of salt water was greater than Mr. Humpty.
Why did Mr. Humpty float in salt water?
200

The buoyant force acting on an object equals the weight of the fluid displaced.

What is Archimedes' Principle?

300
Less than 1.0g/mL
What is the density of an object the floats in water?
300
Density X Volume
What is the formula for mass?
300
The tendency of the material to rise or float in a liquid.
Define Buoyancy?
300

Mr. Nemo (fish) will have neutral Buoyancy.

What type of buoyancy would a Mr. Nemo ( fish) have that is’nt at the bottom of the lake and is’nt at the top of the surface?

300
Gravitational Force and Buoyant force.
What are the two forces acting on an object submerged in a liquid?
400
Units for Density are g/mL or g/cm3
What are the units for Density?
400
volumn= Length x Width x Height
How will you calculate volumn of rectangle or square?
400
Total mass of an object divided by total volumn.
What is average density?
400
The density of a substance will Decrease. Molecules spread out And takes up more volume. The Mass stays the same.
Explain what happens to the density of a substance that is heated?
400
To figure out if an object sinks or floats in water, & density is an important physical property of an element.
Why is density important to understand?
500
Newtons.
Buoyant force is measured in------.
500
By submerging the object in water and measuring how much the volume of the water increases. This amount of displaced water represents the volume of the submerged object.
How will you find the volumn of an irregular object?
500
The upward force excerted on an object submerged in the fluids.
What is Buoyant force?
500
The Diet Cola floated because of lower density that Regular Cola.
What would happen if you drop Regular and Diet cola in water?
500
When temperatures rise, the gas expands and becomes less dense than surrounding air and hot air balloon floats.
How does Hot air balloon float in air?
