Summary
take care when calculating: remember the BIDMAS rule
Numbers and Operations
Basic numeracy skills

So you think you can add, subtract, multiply & divide?
working with Formulae
use a formula to calculate a result
derive a formula from data
BIDMAS
working with DATA

Maths for SporT
1 - working with numbers;

2 - working with data, drawing graphs and dealing with formulae;

3 - formulae and equations

4 - working with kinematics
The order of operations:

RULES for calculating...

Maths, numeracy & statistics
THINK about data before plotting a graph of it
THINK about a formula before using it
look for patterns
represent the data graphically

Plotting graphs of data:

- is the data CONTINUOUS or DISCRETE ?
(eg: you can't plot discrete data as a line or scatter
graph)

- the horizontal axis is the INDEPENDENT variable -
this is the variable that you
set
or
choose

- the vertical axis is the DEPENDENT variable - this is
the variable that you
record
or
measure

if F = 42, C = ?
v = v + a.t

calculate v
f
v = 7 m/s , a = 0.25 m/s, t = 12 s

5 - exam practice
v = v + a.t
f
calculate v

v = 7 m/s , a = 0.25 m/s, t = 12 s

v = 10.5 m/s v = 7 m/s a = 0.25 m/s

calculate t
calculate v
f
v = 8.2 m/s , a = 0.3 m/s, t = 11.4 s

Re-arrange the formula

v = v + a.t

to make 't' the subject

Two cyclists in a competition cover the same stage almost together;

Both take the same time to cover the stage, and both cross the start line of the stage at the same velocity.

Cyclist A crosses the stage finish line with a velocity of v = 13 m/s and his acceleration through the stage was measured at a = 0.05 m/s

Cyclist B crosses the stage finish line with a velocity of v = 11 m/s and his acceleration was measured at a = 0.03 m/s

Was was their initial velocity, v , and how long did the stage take?
