Buoyancy Force, Viscous Force, Surface Tension and Pascal's Law.
In this session, we will learn about different forces exerted by liquid:
We will also learn about reaction of liquid when force is applied by understanding Pascal's Law.
Weight of water at A is because by water above point.
Weight of water at B is because of water above B.
We know that pressure exerted by liquids are because of their weight.
So pressure is more at point B than A.
If you make holes at A and B points, water will come out with stronger jet.
Buoyancy force acts only when low density object is dipped in a liquid.
True or False?
For an object which has higher density than liquid do not have any buoyancy force acting on it.
A boat floats on water because of ___________________
Boats are made from material which are less denser compared to water.
Generally wood is used in base part of boat which is less denser than water.
Can we say that using pascal's law, we can transfer force without loosing it's effectiveness.
Effectiveness of force is nothing but pressure.
According to pascal's law, pressure exerted at any point of liquid is experienced at all other locations of liquid.
Which of the following a contact force?
Tip: Think before answering.
Which force is responsible for mosquito to sit on water surface?
Surface of water or a liquid has more molecule compare to deep regions.
True or False?
Which one will consume less energy?
Driving boat on water will consume less energy as it has less viscosity compared to oil.
Water form drops because of __________________
