Methane. The importance of methane in the greenhouse effect is its warming effect. Even though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.Methane accounts for 20% of the 'enhanced greenhouse effect'.ven though it occurs in lower concentrations than carbon dioxide, it produces 21 times as much warming as CO2.

On a horizontal surface, the gravitational force is equal to the object's weight, as is the normal force. But now the parallel force is the mass of the object * g * sin (theta), where g is the acceleration due to gravity (9.8 m/s^2), and theta is the angle of the inclined plane. For the perpendicular vector, the magnitude is the mass of the object * g * cos (theta).
Work (physics) - Constraint forces. 1  Constraint forces determine the movement of components in a system, constraining the object within a boundary (in the case of a slope plus gravity, the object is stuck to the slope, when attached to a taut string it cannot move in an outwards direction to make the string any 'tauter').
