Galileo defined speed as the distance covered per unit of time. Speed DistanceTime 1000 km0001 seconds 1000000 kmseconds. Distance-time and velocity-time graphs can be a useful way of analysing motion.
All of the calculations in this section will be worked out using the distance speed and time formulae.
1 To compute the Speed. Time frac DistanceSpeed. Simple formulas are as given below. The most common equation for speed is.
