PRESSURE Pressure is defined as the perpendicular force per unit area acting on a surface. It is a scalar quantity & measured in N/m2 or Pascal (pa).It can also be… Read More »PRESSURE, ARCHIMEDES’ PRINCIPLES, UPTHRUST & LAWS OF FLOATATION
Pressure is defined as the force acting normally (perpendicularly) per unit area . The SI units for pressure is newton per metre squared (N/m2). One Nm-2 is known as one Pascal… Read More »PRESSURE
PRESSURE SYSTEMS IN THE WORLD Cyclone It’s a low pressure system characterised by low pressure at the centre and increases outwards. Starts in areas where air ascends from the ground… Read More »PRESSURE SYSTEMS IN THE WORLD
ATMOSPHERIC PRESSURE Factors Influencing Atmospheric Pressure Altitude Pressure decreases with increase in altitude because the column of air becomes shorter hence it exerts less weight. Temperature When air is heated… Read More »ATMOSPHERIC PRESSURE
