Variables
What you change
- Moving distance
What you measure
- Speed
What you keep constant
- Initial position
- Air Resistance
- Surface flatness
Equations
d = Distance
t = Time (1 s)
S = Speed (\frac{m}{s})
S = (\frac{d}{t})

Mind-Blowing Fact
Rock solid.
Sound travels 35x faster when travelling through diamond when compared to the speed of sound in the air. This is due to how stiff diamond is.
