Floating
100
The amount of mass per unit volume of material.
What is density?
100
It is an upward force on an object exerted by a fluid.
What is buoyant force?
100
Force per unit of area applied on the surface of an object.
What is pressure?
100
Being more dense then the substance it is submersed in
What makes an object sink?
100
Being less dense then the substance it is submerged in.
What makes an object float?
200
Density Equation.
What is d=m/v
200
The weight of the displaced fluid is equal to the buoyant force.
What is Archimedes Principle?
200
Force exerted per unit area by air particles
What is atmospheric pressure?
200
It would sink
What would happen if you put a stick with the density of 1.3 in water?
200
It would sink.
What would happen if you put a stick with a density of 1.3 in water?
300
Mass of particles and distance between particles.
What does density depend on?
300
Pressure exerted by a fluid increases with ____________.
What is depth?
300
When the depth of a fluid invrease
What is the time that pressure exerted by a fluid increases?
300
The downward force of gravity.
What is the force that makes an object sink?
300
If the buoyant force is greater than the downward force, it will float.
What does buoyant force have to do with floating?
400
The method used to determine the volume of an irregularly shaped object.
What is the displacement method?
400
The buoyant force and gravity are balanced.
What keeps a floaty from sinking?
400
The downward force
What is the strongest force on a rock that is sitting on the bottom a pong?
400
Pressure exerted by a fluid increases with depth.
What is the effect depth has on sinking
400
The hot air
What makes a hot air balloon rise?
500
It doesn't depend on size
How does density depend on size
500
All forces acting on an object.
What is the net force?
500
A Barometer
What is the tool used by meteorologists to keep track of pressure?
500
1
What is the density of water?
500
The hot air inside rises, making it float in the air.
