equal but opposite
Forces always occur in equal and opposite directions, under Equilibrium Conditions.
In pairs. Newton's third law.
Pairs!
It states that if an object "A" exerts a force on object "B", then there will be a force of equal magnitude, and in the opposite direction, from object "B" against object "A". Thus, the forces always come in pairs.
Forces always occur in pairs. They even have reaction force pairs occur when there is no motion
Interpreting the question as follows... "When is an object in equilibrium according to its component forces?"When all component forces cancel leaving no resultant force.For example - If Joe pulls on a crate with a force of 10 Newtons North, and Sally pulls on the same crate at the same time with a force of 10 Newtons South then all of the component forces combine to give a resultant force of zero. Thus the crate is in equilibrium. Math: 10 + (-10) = 0
Yes, but not nesicarially equally. "In every interaction, forces always occur in pairs. For example, in walking across the floor you push against the floor, and floor pushes against you. Likewise, the tires of a car push against the road, and the road in turn pushes back in the tires. In swimming you push the water backward, and the water pushes you forward. There is a pair of forces acting in each instance. The forces in these examples depend on friction; a person or a car on ice, by contrast, may not be able to exert the action force against the ice to produce the needed reaction force." -Conceptual Physics by Paul G. Hewitt
The two forces occur at the same time. Sometimes it is a bit arbitrary which force you call "action", and which "reaction". Just remember that forces always occur in pairs.

Sort of; it's true as stated, but remember that any measured force may be the resultant of two or more initial forces. But the end result is identical to two equal & opposing forces.
1. Contact forces: Push, pull, tension. 2. Long range forces: Gravity, electromagnetism. That's all I have. I did some research on the Internet on this question, because it will be on my Physics final in high school.
Newton's third law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object (action), the second object exerts an equal force in the opposite direction on the first object (reaction). These action and reaction forces always occur in pairs and act on different objects.
