2. Kinematics
2.1 Equations of motion
- Define and use distance, displacement, speed, velocity and acceleration
- Use graphical methods to represent distance, displacement, speed, velocity and acceleration
- Determine displacement from the area under a velocity–time graph
- Determine velocity using the gradient of a displacement–time graph
- Determine acceleration using the gradient of a velocity–time graph
- Derive, from the definitions of velocity and acceleration, equations that represent uniformly accelerated motion in a straight line
- 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
- Describe an experiment to determine the acceleration of free fall using a falling object
- Describe and explain motion due to a uniform velocity in one direction and a uniform acceleration in a perpendicular direction
