SPEED In this section you will review how to calculate the speed of an object interpret distance time graphs be introduced to the idea of average speed
. __ Speed = Copy these notes and equation into your books:- To work out the speed something is travelling with we need to measure 2 things:- the the object has travelled the it takes for the journey Speed = __ . (in metres) (in seconds) (in metres per second or m/s)
. __ Speed = distance time Copy these notes and equation into your books:- To work out the speed something is travelling with we need to measure 2 things:- the distance the object has travelled the time it takes for the journey answers Speed = distance time __ . (in metres) (in seconds) (in metres per second or m/s)
speed - = m Speed = m/s - = s
answer Constant speed 12-4=8m Speed = 8/3 Speed = 2.67m/s 6-3=3s
Constant speed of Average speed of 1.2m/s Fill in the missing speeds Average speed of 2.4m/s (changes direction) Average speed of 1.2m/s
Constant speed of 1.5m/s 0m/s 1m/s 6m/s 0m/s 4m/s 4m/s 2m/s Average speed of 2.4m/s (changes direction) Average speed of 1.2m/s
