Newton's third law states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object will exert an equal and opposite force back on the first object.
One of the main problems with Newton's third law is that it does not take into account friction and air resistance. In real-life scenarios, these forces can affect the equal and opposite reaction, making it not completely equal. Another problem is that the forces may not always act on the same objects, making it difficult to determine which object is exerting the action and which is exerting the reaction.
No, Newton's third law is a fundamental law of physics and has been proven to hold true in countless experiments. However, there are certain situations, such as electromagnetic forces, where it may seem like the law is being violated, but in reality, it is still being followed.
Newton's third law can be seen in many everyday situations, such as when walking, pushing a shopping cart, or riding a skateboard. When we walk, we push against the ground, and the ground pushes back with an equal and opposite force, propelling us forward. Similarly, when we push a shopping cart, our force on the cart is matched by the cart's force back on us, causing us to move in the opposite direction.
Newton's third law affects motion by ensuring that forces are always balanced. This means that if one object exerts a force on another object, the second object will exert an equal and opposite force back. This allows for objects to move and interact with each other in a predictable manner, following the laws of physics.
