Newton's first law states that objects maintain their state of motion unless acted upon by an external force, highlighting the concept of inertia.
Newton's first law, also known as the law of inertia, states that an object at rest will remain at rest or in motion at a constant velocity unless acted upon by an external force.
For example, if a hockey puck is sliding on ice with no friction, it would continue moving forever due to this law unless an external force, like friction, stops it.
In summary, Newton's first law emphasizes that objects maintain their state of motion unless an unbalanced force intervenes.
