- Subtract the weight in air by weight in liquid
4
Q
Gravity?
A
The force that attracts an object toward the center of the earth
5
Q
3 Types of Buoyancy (Positive)
A
The object is floating
Buoyant force > gravity
6
Q
3 Types of Buoyancy (Negative)
A
The object is sinking
Gravity < buoyant force
7
Q
3 Types of Buoyancy (Neutral)
A
