(i) the equations of motion for constant acceleration in a straight line, including motion of bodies falling in a uniform gravitational field without air resistance

$v = u + at$

$s = \Big(\dfrac{u+v}{2}\Big)t$

$s= ut + \dfrac{1}{2}at^2$

$v^2 = u^2 + 2as$

(ii) techniques and procedures used to investigate the motion and collisions of objects

PAG1 - Apparatus may include trolleys, air-track gliders, ticker timers, light gates, data-loggers and video techniques.

(i) acceleration g of free fall

(ii) techniques and procedures used to determine the acceleration of free fall using trapdoor and electromagnet arrangement or light gates and timer

PAG1

reaction time and thinking distance; braking distance and stopping distance for a vehicle.
