efferent arteriolar constriction.
Increased sympathetic activity causes the afferent arterioles of the renal glomerulus to constrict, thereby reducing blood flow into the glomerulus. Because a decrease in blood flow reduces blood pressure in the glomerulus, which is the driving force for filtration, GFR decreases.
Is increase in blood pressure in the capillaries

When the afferent arteriole is constricted it causes blood to be unable to flow into the glomerulus, overall decreasing hydrostatic pressure and causing the bowman's capsule to decrease filtration.
Hydrostatic pressure. The vessel draining the glomerulus has a smaller internal diameter than the vessel feeding it. This means that blood doesn't exit the glomerulus as quickly as it enters. This creates a pressure, called hydrostatic pressure, within the glomerular capillaries and that pressure forces the fluids and many solutes into the glomerular capsule surrounding the glomerulus.
In glomerulonephritis, the glomerulus in the nephrons of the kidneys become clogged and are unable to filter the plasma to turn it into urine. Your vessels become overloaded with fluid. This causes an increase in H20 because it is not being filtered out and a decrease in the concentration of Na+.

Division.
Friction causes heat. Fraction causes heat only with people who are not comfortable with maths.
One thing that causes the greatest increase of motion of molecules is an increase in temperature.
An increase in volume or velocity of the water will increase erosion
