Motion with i\mathbf{i}i and j\mathbf{j}j components
Motion with i\mathbf{i}i and j\mathbf{j}j components
Further kinematics describes motion in a plane using unit vectors i\mathbf{i}i and j\mathbf{j}j. In many questions i\mathbf{i}i is east and j\mathbf{j}j is north, so 3i−4j3\mathbf{i}-4\mathbf{j}3i−4j means 3 units east and 4 units south.
Step-by-step lessons covering Edexcel A Level Maths Further Kinematics for A Level Maths. Each lesson breaks down 8.1 Vectors in Kinematics, 8.2 Vector Methods with Projectiles, 8.3 Variable Acceleration in One Dimension, 8.4 Differentiating Vectors, and 8.5 Integrating Vectors, then works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
