**Harmonic Motion:****Specific Expectations**

**The Ontario Curriculum for Grades 11 and 12 Science:**

**C2.1:** use appropriate terminology related to energy and momentum, including, but not limited to: work, work–energy theorem, kinetic energy, gravitational potential energy, elastic potential energy, thermal energy, impulse, change in momentum impulse theorem, elastic collision, and inelastic collision [C].

**C2.3**

**using an inquiry process to analyse, in qualitative and quantitative terms, situations involving work, gravitational potential energy, kinetic energy, thermal energy, and elastic potential energy, in one and two dimensions (e.g., a block sliding along an inclined plane with friction; a cart rising and falling on a roller coaster track; an object, such as a mass attached to a spring pendulum, that undergoes simple harmonic motion), and use the law of conservation of energy to solve related problems [PR, AI]**

**(The ontario curriculum,p.201)**

**C2.4:**

**conduct a laboratory inquiry or computer imulation to test the law of conservation of energy during energy transformations that involve gravitational potential energy, kinetic energy, thermal energy, and elastic potential energy (e.g., using a bouncing ball, a simple pendulum, a computer simulation of a bungee jump) [PR, AI]**

**(The ontario curriculum,p.201)**

**C2.5**

**analyse, in qualitative and quantitative terms, the relationships between mass, velocity, kinetic energy, momentum, and impulse for a system of objects moving in one and two dimensions (e.g., an off-centre collision of two masses on an air table, two carts recoiling from opposite ends of a released spring), and solve problems involving these concepts [PR, AI]**

**(The ontario curriculum,p.201)**

**C3.1**

**describe and explain Hooke’s law, and explain the relationships between that law, work, and elastic potential energy in a system of objects.**
