#3.1.2a
(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.
#3.1.2b
(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
#3.1.2c
reaction time and thinking distance; braking distance and stopping distance for a vehicle.
