What you need to know
- Define and calculate average speed using speed = distance / time
- Sketch and interpret distance-time graphs: gradient = speed
- Define velocity as speed in a given direction
- Define acceleration as change in velocity divided by time; calculate using a = (v – u) / t
- Sketch and interpret speed-time graphs: gradient = acceleration, area under graph = distance
- Apply the equations of uniformly accelerated motion to solve problems (Supplement)
- State that the acceleration of free fall near the Earth's surface is approximately 10 m/s²
- Describe terminal velocity and explain the forces acting on a falling object
