∟Introduction of Speed

This chapter provides an introduction of speed. Topics include definition of speed; dependency of speed on frame of reference; measuring speed of light.

What Is Speed

List of Various Speeds

Different Speeds Observed in Different Frames

Measuring Speed of Light - Roemer's Method

Measuring Speed of Light - Fizeau's Method

Measuring Speed of Light - Foucault's Method

Takeaways:

• The speed of a moving object is the distance it has moved within a single unit of time.
• The speed of light is 299,792,458 m/s, which is the fastest speed of an object can move known today.
• In 1857, Léon Foucault made a measurement of the speed of light as 299,796,000 m/s using a rotating mirror and a fixed mirror.
