Newton's First Law of Motion

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 remain in motion with a constant velocity, unless acted upon by an external force. This means that an object will not change its state of motion unless a force is applied to it.

In equation form, it can be represented as:

[ \Sigma F = 0 ]

This law is fundamental in understanding the concept of inertia and how objects behave under the influence of forces.
