Final answer:
The force due to gravity acting parallel to the inclined plane is given by the formula wx = mg sin(θ) and increases with the angle of the incline.
Step-by-step explanation:
The force due to gravity acting parallel to an inclined plane is a component of the total gravitational force exerted on an object. This component can be calculated using the formula wx = mg sin(θ), where wx is the parallel component of the weight, m is the mass of the object, g is the acceleration due to gravity, and θ is the angle of the incline with respect to the horizontal. As the angle of the incline increases, the magnitude of the parallel component of gravitational force also increases, as it is directly proportional to the sine of the angle of the incline.
