The document discusses Newton's Third Law of Motion, which states that for every action there is an equal and opposite reaction. It provides several examples to illustrate this law, including rockets propelling upwards as hot gases push down, cars moving forward as wheels push backwards on the road, a baseball hitting a bat causing the bat to push the ball in the opposite direction, and birds staying aloft as their wings push down on the air causing the air to push up with an equal force. Fish are also able to propel forward as their fins push water backwards with an opposing force. In each case, the size and direction of the action and reaction forces are equal and opposite.

The forces exerted by two objects on each other are often called an action-reaction force pair. Either force can be considered the action force or the reaction force. Action and reaction force pairs dont cancel because they act on different objects.
Newtons Third Law of Motion states: For every action, there is an equal and opposite reaction.
The reaction of a rocket is an application of the third law of motion. Various fuels are burned in the engine, producing hot gases. The hot gases push against the inside tube of the rocket and escape out the bottom of the tube. As the gases move downward, the rocket moves in the opposite direction.
Consider the motion of a car on the way to school. A car is equipped with wheels which spin backwards. As the wheels spin backwards, they grip the road and push the road backwards.
The baseball forces the bat to the left (an action); the bat forces the ball to the right (the reaction).
Flying gracefully through the air, birds depend on Newtons third law of motion. As the birds push down on the air with their wings, the air pushes their wings up and gives them lift.
Consider the flying motion of birds. A bird flies by use of its wings. The wings of a bird push air downwards. In turn, the air reacts by pushing the bird upwards. The size of the force on the air equals the size of the force on the bird; the direction of the force on the air (downwards) is opposite the direction of the force on the bird (upwards). Action-reaction force pairs make it possible for birds to fly.
Consider the propulsion of a fish through the water. A fish uses its fins to push water backwards. In turn, the water reacts by pushing the fish forwards, propelling the fish through the water. The size of the force on the water equals the size of the force on the fish; the direction of the force on the water (backwards) is opposite the direction of the force on the fish (forwards).
