Mechanics content

Subject content Revise work on vectors and analysing motion using graphs and equations.The topics of mechanical systems that you may be assessed on will include: Translational motion: centre of mass (1 and 2 dimensions) conservation of momentum and impulse (2 dimensions only). Circular and rotational motion: velocity and acceleration of, and resultant force on, objects moving in a circle under the influence of 2 or more forces, for example, banked corners, vertical circles Newton’s law of gravitation, satellite motion rotational motion with constant angular speed and with constant angular acceleration torque rotational inertia angular momentum rotational kinetic energy conservation of angular momentum conservation of energy. Simple harmonic motion: displacement velocity acceleration time and frequency of a particle undergoing SHM forced SHM resonance the reference circle phasors conservation of energy.
