action-reaction pair and equal and opposite?

Question

when asked these 2 separate questions, what are you supposed to be thinking? I'm confused what's the difference between
a) are these forces equal and opposite?
b) are these forces an action-reaction pair?
examples would be great and use simplistic words to explain.

Answer 1

A) these forces are equal but definitely opposite.
B) Yes they do form an action-reaction pair. As you push against the wall (action )the wall returns the favor by pushing back with an equal but apposing force ( reaction). If it fails to do so you will either move the wall or fall trough. for more see the ref provided.

have fun!

Answer 2

as newton`s third law say...'every force has an equal and opposite reaction..' so to cause a reaction a force must first act.... that means reaction will take place only after action.... they dont exist together, so they wont cancel each other... just consider a rocket taking off...the thrust from its burner(action force)..the reaction force by the ground on the rocket(reaction)...which is after the thrust....
