Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means that if one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object.
For example, when you push against a wall, the wall pushes back with an equal force. Even though the wall doesn’t move, it still exerts a reaction force equal to the force you apply. This law explains interactions between objects and how forces work in pairs.
Examples
Here are 20 examples of Newton's Third Law of Motion along with explanations:
1. Walking
When you walk, you push the ground backward with your feet. In return, the ground pushes you forward with an equal and opposite force, propelling you ahead.
2. Jumping off a diving board
As you push down on the diving board, the board pushes you up with an equal and opposite force, allowing you to jump into the air.
3. Bird flying
A bird pushes air downward with its wings. The air pushes the bird upward with an equal force, helping it stay in the air.
4. Rowing a boat
When you row, you push the water backward with the oars. In response, the water pushes the boat forward with an equal and opposite force.
5. Rocket propulsion
A rocket expels gas out of its engines in one direction (action), and in response, the rocket is pushed in the opposite direction (reaction), enabling it to launch into space.
6. Swimming
When a swimmer pushes water backward with their hands and feet, the water pushes them forward, helping them move through the water.
7. Recoil of a gun
When a bullet is fired from a gun, the force exerted to propel the bullet forward (action) causes the gun to move backward (reaction) with an equal force, which is felt as recoil.
8. Tug of war
In a tug of war, when you pull the rope, the rope pulls you back with an equal force. If the other team pulls harder, they overcome the reaction force and win.
9. Car tires on the road
As the car tires push the road backward (action), the road pushes the car forward (reaction), enabling the car to move.
10. Kicking a football
When you kick a football, your foot applies a force to the ball (action), and the ball exerts an equal force back on your foot (reaction), although you may not feel it as strongly.
11. Paddling a kayak
When you push water backward with your paddle, the water pushes the kayak forward, allowing you to move through the water.
12. Jumping off a trampoline
You push down on the trampoline, and the trampoline pushes you upward with equal force, propelling you into the air.
13. Inflating a balloon
When air is released from an inflated balloon, the air pushes out in one direction, and the balloon moves in the opposite direction.
14. Punching a wall
When you punch a wall, your fist applies a force on the wall, and the wall exerts an equal and opposite force on your fist, which is why it hurts.
15. Jet engine thrust
A jet engine pushes air backward at high speeds, and the air pushes the jet forward with an equal force, enabling it to fly.
16. Pushing a skateboard
When you push against the ground while standing on a skateboard, the ground pushes you and the skateboard forward in the opposite direction.
17. Opening a door
When you push a door, the door pushes back on your hand with an equal and opposite force. However, since the door is on hinges, it moves open.
18. Hammer hitting a nail
When you strike a nail with a hammer, the hammer exerts a force on the nail, and the nail exerts an equal force back on the hammer.
19. Standing on the ground
Your weight pushes down on the ground (action), and the ground pushes back up with an equal force (reaction), allowing you to remain standing.
20. Bouncing a ball
When you throw a ball to the ground, it exerts a force on the ground (action). The ground then exerts an equal and opposite force back on the ball (reaction), causing it to bounce.
These examples illustrate how every action is met with an equal and opposite reaction, which is the essence of Newton’s Third Law of Motion.
