Φόρμουλες
Ταχύτητα: v = d / t
Απόσταση: d = v × t
Φορά: t = d / v
v = speed, d = distance, t = time
Speed Units
km/h: Kilometers per hour
mph: Miles per hour
m/s: Meters per second
knots: Nautical miles per hour
ft/s: Feet per second
Common Conversions
1 km/h = 0.621371 mph
1 mph = 1.60934 km/h
1 m/s = 3.6 km/h
1 knot = 1.852 km/h
Example Calculations
Ταχύτητα: 100 km in 2 hours = 50 km/h
Απόσταση: 60 km/h × 3 hours = 180 km
Φορά: 300 km ÷ 100 km/h = 3 hours
Σημαντικές Σημειώσεις
- Speed is a scalar quantity (magnitude only)
- Velocity includes direction (vector)
- Average speed = total distance / total time
- Instantaneous speed is speed at a moment
- Units must be consistent for accurate results
