Explain Newton’s First Law of Motion.

1 answer

Newton's First Law of Motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line with a constant velocity, unless acted upon by an external force.

In simpler terms, this law suggests that objects have a natural tendency to resist changes in their state of motion. If an object is not moving, it will stay still unless a force is applied to it. Likewise, if an object is already in motion, it will continue moving in the same direction at the same speed unless acted upon by an external force.

The concept of inertia is crucial to understand Newton's First Law. Inertia refers to an object's resistance to change in its motion. The more massive an object is, the greater its inertia, making it more difficult to change its speed or direction.

To summarize, Newton's First Law of Motion essentially tells us that objects will maintain their existing state of motion unless an external force is applied. This principle applies to objects at rest as well as objects in motion.
