Factors that can be controlled
Volume
The amount of space an object takes up in a 3 dimensional figure
Density of an object ___ will FLOAT in H2O
Less than 1.0 g/cm^3
Density of an object ___ will SINK in H20
Greater than 1.0 g/cm^3
Mass
The amount of matter in an object
Calculate density using water displacement
- Find mass
- Find final volume (vF-vI=V)
- Density= mass/volume
Calculating density of regular shaped object
- Find mass
- Volume=LWH
- Density = mass/volume
Equation for volume
LWH
VF-VÍ=V
Equation to find volume=
M/D
Equation to find density
D=M/V
Equation to find mass=
Mass= Density* Volume
