Final answer:
Newton's first law, the law of inertia, might seem contradicted in everyday life when objects in motion don't stay in motion, but this is a result of unbalanced forces such as friction acting on the object. When these forces are considered, everyday experiences are in fact consistent with Newton's law.
Step-by-step explanation:
Newton's first law, also known as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. However, in everyday life, it seems like this law is contradicted.
For example, if you slide a book on a table, it eventually stops rather than continuing to move indefinitely. This apparent contradiction doesn't mean Newton's law is incorrect.
What's happening is that frictional forces, such as air resistance and the friction between the book and the table, are acting on the book to slow it down. These are the 'unbalanced forces' that Newton's first law mentions. Therefore, the observed behaviors in our daily life are perfectly consistent with Newton's first law when you take into account all the forces at play.
