Not the opposite, but the complementary form, is grabbing.
The opposite of pinching would be spreading, as can be seen when working with torn materials, or such forms as buttonholes : pinching it closes a hole, spreading it opens the hole.
The opposite of a pinching motion (e.g. fingers coming together) would be a "spreading" motion (e.g. fingers moving apart).
A motion close to this anatomically is a flicking motion (fingers together are moved outward.
The friction will be on the opposite side of the motion.
If force is applied in the line of motion, then motion will increase, but when it is applied opposite to the line of motion, then motion will decrease.
Motion
A force applied to a moving object in the opposite direction of its motion causes its velocity to decrease.
Centrifugal motion is an outward force on a body rotating about an axis. It is the opposite of centripetal force.
Median nerve
Static means at rest, so the opposite would be motion.
the motion is in opposite direction
An example of such a force is friction, but a term for forces that act against motion are decelerative forces.Newton's Third Law states that for every action, there is an equal and opposite reaction. However, these can be in any direction and may or may not influence an object in motion.
it acts in the opposite direction of motion or force
Friction.
The friction will be on the opposite side of the motion.
Motion
If force is applied in the line of motion, then motion will increase, but when it is applied opposite to the line of motion, then motion will decrease.
A force applied to a moving object in the opposite direction of its motion causes its velocity to decrease.
The opposite reaction of to sink (in liquid) is to float.However the opposite motion sink (move lower) would have the opposite rise.
By definition, friction is opposite of the direction of motion.
