Linear Motion

the straight-line distance between the start and finish positions of a moving object

the diagonal distance between the start and finish positions of a moving object

the straight-line distance between the middle and finish positions of a moving object

the straight-line distance of a moving object

Rearranging formula

No, I am confident with the LOs covered in todays session

Parameter units and symbols

Equations for linear motion

Definitions of linear motion parameters

Displacement (s) measured in metres (m)

Displacement (d) measured in centimetres (cm)

Displacement (s) measured in inches (in)

Displacement (x) measured in meters (m)

Because the formulas only work if all values are in the correct units

Because each parameter has a base unit

Because it looks good

It doesn't matter
