作用・反作用の表現例

REACTION FORCES
FORCES ON A LEVEL SURFACE
A table provides a force called a reaction, which exactly balances the weight of an object placed upon it. The resultant force is zero, so the object does not fall through the table.
FORCES ON A SHALLOW SLOPE
Gravity acts downward on the 1 kg mass shown. The slope provides a reaction force that acts upward, perpendicular to the slope and counteracts some of the weight. All that remains of the weight is a force acting down the slope.
FORCES ON A STEEP SLOPE
As the slope is made steeper, the reaction force of the slope decreases, and the force pulling the mass down the slope - which is measured by the newton meter - increases. This force can pull objects downhill.

The law that at any given instant the sum of instantaneous values of all the currents flowing toward a point is equal to the sum of instantaneous values of all the currents flowing away from the point.
