1
Q

A
Liquid pressure is when you might swim underwater and you feel the pressure on you the water molecules are pushing on each other and on the surface and this liquid pressure acts in all directions.
2
Q

3
Q
What is upthrust?
A
Thrust acts on any object that is floating or submerged in a liquid.
4
Q
How would you figure out the pressure in this equation?
A boat has an area of 10 m² and a weight of 1000 N it sinks to a lower depth figure out the pressure.
A
1000 N
———- = 100 N/m2
10 m2
5
Q
What is the unit for pressure
A
Pa or pascals
