Answer:

Knowledge points:

3.1.1 define and use distance, displacement, speed, velocity and acceleration

3.1.2 use graphical methods to represent distance, displacement, speed, velocity and acceleration

3.1.3 determine displacement from the area under a velocity-time graph

3.1.4 determine velocity using the gradient of a displacement-time graph

3.1.5 determine acceleration using the gradient of a velocity-time graph

3.1.6 derive, from the definitions of velocity and acceleration, equations that represent uniformly accelerated motion in a straight line

3.1.7 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

3.1.8 describe an experiment to determine the acceleration of free fall using a falling body

3.1.9 describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction
