Some examples of Newton’s third law are When a car accelerates forward, the tires push backward against the road, When you swim, you push the water backward with your arms and legs, When you release air from a balloon, the air rushes out in one direction When you row a boat, the oars push against the water, etc.

Newton’s third law of motion, often referred to as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This principle describes the relationship between forces acting on two interacting objects. Newton’s third law of motion highlights the fundamental principle that forces exist in pairs and are interdependent on the interactions between objects.

## Newton’s Third Law Of Motion

Newton’s third law of motion, often referred to as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This principle describes the relationship between forces acting on two interacting objects.

According to Newton’s third law:

• Action: When one object exerts a force on a second object, it is referred to as the action force. This force is exerted by one object onto another.
• Reaction: Simultaneously, the second object exerts an equal but opposite force on the first object, which is referred to as the reaction force. The reaction force acts on the object that initiated the action force.

Solution:

Newton’s third law of motion states that for every action, there is an equal and opposite reaction. Here are some examples of Newton’s third law in action:

• Jumping off a Boat: When a person jumps off a boat and pushes against it (action), the boat moves backward slightly (reaction) due to the equal and opposite force exerted by the person.
• Balloon Rocket: When you blow up a balloon and let it go, the air rushes out of the balloon in one direction (action), and the balloon moves in the opposite direction (reaction) due to the equal and opposite force exerted by the air.
• Walking: When you walk, your foot pushes against the ground (action), and the ground pushes back with an equal and opposite force (reaction), propelling you forward.
• Swimming: When you swim, you push against the water with your arms and legs (action), and the water pushes back on you with an equal and opposite force (reaction), propelling you through the water.
• Pushing a Wall: When you push against a wall with your hand (action), the wall exerts an equal and opposite force back on your hand (reaction), causing you to feel the resistance or pressure.
• Firing a Gun: When a gun is fired, the expanding gases push the bullet forward (action), and the bullet pushes back on the gases with an equal and opposite force (reaction).
• Bouncing a Ball: When you throw a ball on the ground, the ball exerts a downward force on the ground (action), and the ground exerts an equal and opposite upward force on the ball (reaction), causing it to bounce back up.

These examples demonstrate the concept that any force exerted on an object results in an equal and opposite force exerted by the object in the opposite direction.

Summary:

## Write some examples of Newton’s third law.

Newton’s third law demonstrates the fundamental principle that forces exist in pairs and are interdependent on the interactions between objects. For Example- When you push against a wall, the wall exerts an equal and opposite force back on you. You can feel this as the resistance or pressure pushing against your hand, When a rocket engine expels high-speed gases downward, it experiences an upward reaction force, known as thrust, that propels the rocket forward, etc.
