Modelling motion

11 hours

• Understand and use momentum, constant force, non-constant force, resultant force, action and reaction.
• Understand and use motion of a body in non-equilibrium situations under concurrent forces.
• Understand and use the expressions dv/dt, d²x/dt², v dv/dx and d(½v²)/dx to represent the acceleration of an object moving in a straight line. 1 interactive
• Model and solve problems that involve motion in a straight line with both constant and non-constant acceleration, including simple harmonic motion, vertical motion under gravity with and without air resistance, and motion of a body in non-equilibrium situations on a smooth inclined plane (excluding situations with pulleys and connected bodies). 1 interactive
