Examples
- The Earth is approximately an inertial frame, which is why we don't feel like we're moving when we're standing on its surface.
- In an inertial frame, an object at rest will remain at rest, and an object in motion will continue to move with a constant velocity.
- The concept of an inertial frame is crucial in understanding the laws of motion, as it provides a reference point for measuring the motion of objects.
- A car moving at a constant speed on a straight road can be considered an inertial frame, as long as it's not accelerating or decelerating.
- An astronaut in a spaceship that is not accelerating can consider the ship to be an inertial frame, allowing them to move around freely inside the ship.
