- 1
Newton's first law states that objects at rest stay at rest and objects in motion stay in motion with the same velocity unless acted upon by an unbalanced force.
- 2
The tendency of objects to resist changes in their state of motion is called inertia, which is why Newton's first law is also known as the law of inertia.
- 3
When a bus starts moving, passengers fall backward because their inertia causes them to resist the change in motion, and when a bus stops, they fall forward because their inertia causes them to continue moving.
