As you sit in your chair, your body acts on the chair with one force, and the chair reacts on your body with yet another force. This is an example of Newton's third law in action. Newton's third law states that for every action, there is an equal and opposite reaction.

First law example, I must apply force to move a heavy object, such as my chair or a set of dumbbells. In fact, I have to apply a force, albeit not as much, to move even a lighter object, such as my pencil.

Water coming of from a water plastic pipe with high velocity and that is hold in our hand ...So we realize the reaction force which is exerted by water plastic pipe on our that hand by which we hold the water plastic pipe...

The best example of Newton's law is propelling of rocket where al three laws acts together.

An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called. "the law of inertia". If pulled quickly, a tablecloth can be removed... read more
An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is often called. "the law of inertia". If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass. Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. Rocket propulsion is also a good example of Newton’s Third Law. The exhaust from the rocket pushes the ground and the ground pushes the rocket with equal and opposite force to cause the latter to move forward. If the third law of motion never existed, we would never have made it into the space! Source : Net hope this helps. read less

3rd law example-The recoil that occurs after shooting a gun is due to the third law of motion.

newton first law: any object on your table can be an example for this. the object will remain stationary as long as it is not moved from its place or pushed. 2nd law: this can be considered as an object falling from a height. The gravitational force acting on it will be equal to the mass of the object... read more
newton first law: any object on your table can be an example for this. the object will remain stationary as long as it is not moved from its place or pushed. 2nd law: this can be considered as an object falling from a height. The gravitational force acting on it will be equal to the mass of the object and the gravitational acceleration. 3rd law. for this the rocket launching is the best example. unless a equal amount of push is not applied the rocket cannot be launched or even when we jump we have to put in effort to push the ground to be lifted up read less

Try punching a wall with your fist and what follows is Newton's third law :)

Here are some examples: One's body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it. If pulled quickly, a tablecloth can be removed from underneath... read more
Here are some examples: One's body movement to the side when a car makes a sharp turn. Tightening of seat belts in a car when it stops quickly. A ball rolling down a hill will continue to roll unless friction or another force stops it. If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. Shaking a bottle of ketchup. When bringing the bottom down, the suddenly stopping it, inertia is what causes the ketchup to come out of the bottle. If one drove a car directly into a brick wall, the car would stop because of the force exerted upon it by the wall. However, the driver requires a force to stop his body from moving, such as a seatbelt, otherwise inertia will cause his body to continue moving at the original speed until his body is acted upon by some force. Hovercraft are vehicles that can be a challenge to manipulate because, unlike cars, they do not have the same level of friction, so inertia causes the Hovercraft to want to continue in its same direction without stopping or turning. Abruptly stopping a cart with an object on top causes the object on top to fall off. Inertia causes this by making the object want to continue moving in the direction that it was. If a stopped car is hit by a moving car from behind, the passengers inside may experience whiplash as a result of the body moving forward but the head lagging behind. The head is experiencing inertia. When a car is abruptly accelerated, drivers and passengers may feel as though their bodies are moving backward. In reality, inertia is making the body want to stay in place as the car moves forward. If an index card is placed on top of a glass with a penny on top of it, the index card can be quickly removed while the penny falls straight into the glass, as the penny is demonstrating inertia. If you jump from a car of bus that is moving, your body is still moving in the direction of the vehicle. When your feet hit the ground, the grounds act on your feet and they stop moving. You will fall because the upper part of your body didn’t stop and you will fall in the direction you were moving. When you stir coffee or tea and stop, the swirling motion continues due to inertia. read less
