Define Weight
Weight is the amount of force pulling down on an object
What is the formula for finding volume?
Volume=Length x Width x Height
Define Density
Density is the measure of the amount of matter in a given volume of substance
Define Buoyancy
Buoyancy is the upward force that fluids exert upwards on an object
What are the 3 types of Buoyancy forces?
1. Positive Buoyancy
2. Negative Buoyancy
3. Neutral Buoyancy
Define Mass
Mass is the amount of matter in an object
How do you use an overflow can?
You put the object in the can and the amount of water that is poured out is the volume of the object
What is the formula for calculating Density?
Density= Mass/Volume
True or False: Buoyancy determines whether an object will sink or float?
True
How do swim bladders in a fish work?
The swim bladder takes in oxygen to float upwards and releases the oxygen to sink downward
Define Volume
Volume is the amount an object can hold
How does Finding Volume Using Displacement work?
You put an object in a graduated cylinder with water. The difference between the new water level and the old water level is the volume of the object.
Why is Density considered as a "characteristic property?"
Density is a characteristic property because it is used to distinguish one material from another
Fill in the blanks: Objects that displace a _______ volume of fluid are more buoyant than those that displace ______ fluid
1. Greater
2. Less
How do ballast tanks in submarines operate?
The ballast tank fills up with water to sink downwards and compressed air displaces the water to float upwards
