What should you be able to calculate by the end of this video?
Pressure
due to a
column
of liquid
View source
What happens when holes are made in the side of a water container?
Water
squirts
out, further from the
bottom
hole
View source
Why does water from the bottom hole squirt out further than from the top hole?
Because the bottom water is at higher
pressure
View source
What is the formula to calculate the pressure of a column of liquid?
Pressure
= height ×
density
× gravitational strength
View source
What values are provided in the exam for calculating pressure?
Density
and
gravitational field strength
View source
If a freshwater lake has a depth of 8 meters, what is the pressure at the bottom?
78,400
Pascals
View source
How does pressure change with depth in a liquid?
Pressure increases
with
depth
View source
How does pressure change with the density of a liquid?
Pressure increases
with
density
View source
What is upthrust in relation to floating and sinking objects?
It is the
resultant
upward force on an object
View source
What must upthrust equal for an object to float?
It must equal the object's
weight
View source
What happens if upthrust is less than the object's weight?
The object
sinks
View source
What occurs when an object is lowered into water?
The water level lowers due to
displacement
View source
What is the size of the upthrust acting on an object?
It equals the
weight
of
water displaced
View source
What must an object do to float in water?
Displace
its own
weight
of water
View source
What happens when an object is less dense than water?
It floats after
displacing
small volume
View source
What happens when an object has the same density as water?
It
floats
at the
water's
surface
View source
What occurs when an object is more dense than water?
It sinks because it can't
displace
enough water
View source
Where can you find more questions on pressure in liquids?
In the
vision workbook
View source
What factors influence whether an object floats or sinks?
Density
of the object and
water displaced
View source
What is buoyancy in relation to floating objects?
It is the
upward force
acting on
submerged
objects
View source
How does gravitational field strength affect pressure in liquids?
Higher
gravitational
strength
increases
pressure
