Describe the term ‘inertia’ with respect to motion.
Inertia can easily be described as the reluctance or resistance of a body to change its state of motion i.e. if a body is at rest, it will continue to remain at rest if an external force is not applied to change its state of rest whereas if a body is in motion, it will continue to remain in motion if an external force is not applied to change its state of motion.
