Students learn how to draw and interpret distance – and velocity-time graphs throughout this topic. Later, as learning progresses, they derive the constant acceleration formulae and use them to model vertical motion under gravity.
Students learn how to interpret displacement–time graphs to describe and calculate motion. They start by finding displacement, velocity, and gradients for different time intervals.
As learning progresses, they apply these skills to real-life contexts, calculating average speed, resultant displacement, and interpreting changes in motion direction from the graph’s shape.
Students learn how to interpret velocity–time graphs to analyse motion. They begin by calculating acceleration, displacement, and interpreting when a particle changes direction.
As learning progresses, they apply these skills to determine when the particle is furthest from the start, total distance travelled, and net displacement.
Students learn how to apply the constant acceleration formulae in real-world motion problems. They begin by interpreting motion graphs and using them to derive equations like v = u + at and s = 1/2(u + v)t.
As learning progresses, they model various scenarios involving braking, accelerating, and decelerating motion—calculating displacement, velocity, and acceleration to solve multistep problems.
Students learn how to apply all five constant acceleration formulae to problems involving motion in a straight line. They begin by identifying known values and selecting appropriate equations to find unknowns.
As learning progresses, they derive formulas from first principles and solve multistep problems involving time, displacement, and final velocity.
Students learn how to model vertical motion under gravity using constant acceleration equations. They begin by solving problems involving particles projected upwards or downwards, using a = 9.8 ms^2.
As learning progresses, they interpret motion from different starting heights and calculate times of flight, impact speeds, and displacement intervals.
Students learn how to solve constant acceleration problems involving two objects moving towards each other. They begin by applying the kinematic equations separately for each object to determine when and where the objects meet.
As learning progresses, they compare displacements using a common time variable and solve simultaneous equations.
