Learning outcomes: 1 define and use distance, displacement, speed, velocity and acceleration 2 use graphical methods to represent distance, displacement, speed, velocity and acceleration 3 determine displacement from the area under a velocity–time graph 4 determine velocity using the gradient of a displacement–time graph 5 determine acceleration using the gradient of a velocity–time graph 6 derive, from the definitions of velocity and acceleration, equations that represent uniformly accelerated motion in a straight line 7 solve problems using equations that represent uniformly accelerated motion in a straight line, including the motion of bodies falling in a uniform gravitational field without air resistance 8 describe an experiment to determine the acceleration of free fall using a falling object 9 describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction
