Study Notes
Inertia
- Inertia is the resistance of an object to changing its motion.
- All objects possess inertia, regardless of whether they are still or moving.
- Inertia explains Newton's First Law of Motion.
- Newton's First Law states that a stationary object stays still, and a moving object keeps moving at a constant velocity unless acted upon by an unbalanced force.
- Newton's First Law is also known as the law of inertia.
