Mechanics: State, explain and interpret principles of horizontal motion

• Analyse and calculate more complex problems, using linear equations of motion:
  • [latex]\scriptsize {{v}_{f}}={{v}_{i}}+a\Delta t[/latex]
  • [latex]\scriptsize s={{v}_{i}}\Delta t+\displaystyle \frac{1}{2}a\Delta {{t}^{2}}[/latex]
  • [latex]\scriptsize v_{f}^{2}=v_{i}^{2}+2as[/latex].
• Analyse and interpret graphs of motion: types of motion, direction of motion and turning point:
  • displacement–time graph
  • velocity–time graph
  • acceleration–time graph.
• Calculate and interpret the gradient of:
  • s–t graphs to determine v
  • v–t graphs to determine acceleration.
• Calculate area of v–t graphs to find displacement and distance.
