To increase the angle of a joint is extension. To decrease the angle of a joint is flexion. (plato users the answer is A.)
extension
Yes, if the incline angle becomes great enough. > As the angle increases, the force on the object down the incline increases but the effective weight on the slope surface decreases. > When the object breaks away the angle of incline can be used to calculate the coefficient of friction between the two surfaces. > coefficient of friction = sine ( incline angle ) / cosine ( incline angle )
no
it is the roughness or smoothness between two surfaces
Flexion decreases the angle between two bones in a joint. Extension increases that angle.
acute angle.
Angle is a space between two lines or surfaces that meet at one point, which you measure in degrees.
flexion decreases in angle between articulating bones extension increases in angle between articulation bones
If the angle decreases, the magnitude of the resultant vector increases.
Rotation and supination do not increase or decrease the angle between bones.
It is the angle between the a tangent to the liquid surface at the interface and the solid surface inside the liquid. For concave surfaces, it is acute .
