The condition in which the amount of force pulling down on an object immersed in a fluid (i.e., gravity) equals the amount of force pushing up.
What is neutral buoyancy?
100
A fish has this which increases or decreases the fish's average density. When this is full of air, the overall density of the fish decreases which causes the fish to swim just under the surface of the water.
What is a swim or air bladder?
100
Gravity is measured in this.
What is Newtons?
200
An instrument that measures density.
What is a hydrometer?
200
This is the natural force that causes an object to move toward the center of the Earth.
What is gravity?
200
To move something out of the way (Example: a solid object can cause water to spill out of a full container).
What is to displace?
200
If the weight of the object (object's mass x 9.8 N) is less than the weight of the displaced water, the object will do this.
What is float?
200
Mass is measured in this unit.
What is g or kg?
300
The tendency to rise or float in fluid.
What is buoyancy?
300
Although your ___________ would be the same on Earth as on the Moon, your ____________ would be different.
What is mass and then weight?
300
A push or pull, or anything that causes a change in the motion of an object.
What is a force?
300
The total mass of an object divided by the total volume.
What is average density?
300
If the weight of the object is more than the weight of the displaced water, the object will do this.
What is sink?
400
An upward force exerted on objects submerged in fluid.
What is buoyant force?
400
The buoyant force acting on an object submerged in fluid equals the weight of the fluid displaced by the object.
What is Archimedes Principle?
400
The amount of mass in a certain unit of volume of a substance.
What is density?
400
The largest amount that can be held by a container.
What is capacity?
400
The formula for volume of a rectangular prism.
What is length x width x height.
500
The value equal to the density of a substance.
What is mass to volume ratio?
500
Remaining suspended in a fluid; for example, not falling in air or sinking in water.
What is floating?
500
The area of a surface of an object.
What is surface area?
500
An activity or procedure designed to test a hypothesis.
