Ans. Action-reaction force pairings can be observed in flying birds.
A bird uses its wings to fly. A bird’s wings push air downwards. As force is produced by interaction, the air must be pulling the bird higher as well.
The force on the air is equal to the force on the bird, and the force on the air is opposite the force on the bird.
The direction of forces in this example is upwards(force on the bird’s wings) and downwards( force on the air).
Birds can fly because of action-reaction force pairings.
