Example of using unit m/s

A student run 100 metre in 10 seconds

Example of using unit km/h

F1 car race with a speed of 360 kilometres in 1 hour

Relationship between speed, time and distance

Speed of an object increases if the object travels farther within a set time

Formula of speed

Factors that affected speed

Distance, time

Factor of distance

Travels farther within the same period of time

Factor of time

Takes a shorter time to travel along the same distance
