- Describe the kinematic quantities that describe the circular motion of an object.
- Be able to explain the meaning of analytic expressions for those kinematic quantities. using various physical quantities.
- Be able to explain the direction and magnitude of the acceleration of an object moving in a circle.
- Explain the direction and magnitude of acceleration of an object moving in a circle by vector subtraction of velocities.
- Be able to describe the motion of an object moving in a circular path using appropriate models: constant speed model or non-constant speed model.
- Constant speed model: Be able to describe the direction and magnitude of acceleration of an object moving at constant speed (v) in a circle.
- Non-constant speed model: Be able to describe the tangential component of the acceleration of an object moving in a circle with changing speed.
