Motion - or rather acceleration - occurs as a result of a net force, meaning that the vector sum of forces on an object is non-zero. This is unrelated to "action and reaction"; please note that "action" and "reaction" occur on DIFFERENT OBJECTS.
Action and reaction forces produce motion because for every action force there is an equal and opposite reaction force, as stated by Newton's third law of motion. These forces act on different objects, causing them to accelerate in opposite directions, thus producing motion. When the forces are unbalanced, motion occurs due to the resulting acceleration.
A reaction force is a type of contact force that occurs in response to an action force. It acts in the opposite direction to the action force, according to Newton's third law of motion.
According to Newton's third law of motion, when an action force is applied on an object, the object will simultaneously apply a reaction force of equal magnitude but in the opposite direction on the object that exerted the action force. This means the reaction force occurs instantaneously when the action force is applied.
In accordance with Newton's third law of motion, the reaction force occurs simultaneously with the action force. When one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object in the same instant.

An action is the initial force or movement that occurs, while a reaction is the response or consequence that follows the action. Actions are typically intentional and within our control, whereas reactions are often instinctive or automatic.
according to Newton's third law, every action has an opposite reaction. However, this does not always result in acceleration. As a counterexample, consider pushing on a sturdy wall. You are pushing (that's the "action"). The "reaction" is the wall pushing back on you (if it didn't push back, you would fall through the wall). But since the forces are balanced, nothing accelerates.
When a cannon fires a cannonball, it recoils due to the principle of conservation of momentum. As the cannonball is propelled forward with a certain momentum, the cannon itself must move backward to conserve the total momentum of the system. This reaction occurs in equal and opposite directions, as described by Newton's third law of motion: for every action, there is an equal and opposite reaction. Thus, the forward motion of the cannonball results in the backward motion of the cannon.
No, a reaction force is not a contact force. It is a force that occurs when an object interacts with its environment or another object, and it is equal in magnitude and opposite in direction to the action force.
The "reaction" force.
Acceleration is opposite to the direction of motion when the velocity of an object is decreasing. This occurs when the net force acting on the object is in the opposite direction of its motion, causing it to slow down.
The action and reaction forces occur at the same time.
