This achievement standard involves knowledge and understanding of phenomena, concepts, principles and/or relationships related to translational; circular and rotational; and simple harmonic motion; and the use of appropriate methods to solve related problems.

**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, eg 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 (SHM)**

- Displacement; velocity; acceleration
- time and frequency of a particle undergoing SHM
- forced SHM
- resonance
- the reference circle
- phasors
- conservation of energy.
