The property of inertia was first described by Sir Isaac Newton in his first law of motion, established in the 17th century.
Heavier objects have more inertia, meaning they are harder to start moving or stop moving than lighter ones.

Historical Origins

The term 'inertia' originates from the Latin word 'iners,' meaning 'idle' or 'lazy,' highlighting how still objects tend to stay still.
Aristotle, an ancient Greek philosopher, had previously claimed that force is required to keep an object moving, which was later corrected by Newton’s insights on inertia.
The concept of inertia was a turning point in the scientific revolution, changing how movement was understood and laying the groundwork for classical mechanics.
