Linear Motion

Select the correct definition of displacement

• 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

What symbol is used to represent final velocity

• u

• v

• s

• t

Rearrange v = u + at for u

• $u\ =\ at\ +v$

• $u\ =\ at\ -\ v$

• $u\ =\ v\ -\ at$

• $u\ =\ \frac{v}{at}$
  

Select the correct unit of measure for time

• minutes (min)

• seconds (min)

• seconds (s)

• hours (hr)

What is acceleration measured in

• $ms^{-1}$

• $km\ per\ hr$

• $ms$

• $ms^{-2}$

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

• Parameter units and symbols

• Equations for linear motion

• Definitions of linear motion parameters

What is the correct symbol and UoM for displacement

• Displacement (s) measured in metres (m)

• Displacement (d) measured in centimetres (cm)

• Displacement (s) measured in inches (in)

• Displacement (x) measured in meters (m)

Why is it important to check the UoM of each parameter?

• 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
