Motion Speed (we call this velocity)

How fast is team NZ going? Team NZ has hit speeds of 40 knots which is 74.1 km h -1 (kilometres per hour) In an hour it would cover a distance of 74.1 km This is 20.6 m s -1 (metres per second) In one second the yacht covers a distance of 20.6 metres.

Usain Bolt was declared as the fastest man in the world in He set a world record of 9.58 seconds in the 100 meters sprint which adds up to m s -1 or 37.5 km h -1.

How fast can a cheetah run? Cheetahs can reach speeds of 120 km h -1 This is 33.3 m s -1

How to work out SPEED Find out how FAR (the distance) the object travelled Divide it by how LONG (time) it took v = d/t Velocity = distance time

Work this out If Team NZ sails 44.7 m in 3 s work out how FAST it is sailing? How to show your working List the information d= 44.7 m t= 3 s Write the equation v=d/t Put the numbers instead of letters v=44.7/3 Use your calculator to divide v= 14.9 m s -1 Make sure your units are correct
