**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]. (The ontario curriculum,p.200)

**C2.4:**conduct a laboratory inquiry or computer simulation 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)

**C2.6:**analyse, in qualitative and quantitative terms, elastic and inelastic collisions in one and two dimensions, using the laws of conservation of momentum and conservation of energy, and solve related problems [PR, AI]. (The ontario curriculum,p.201)

**C2.7:**conduct laboratory inquiries or computer simulations involving collisions and explosions in one and two dimensions (e.g., interactions between masses on an air track, the collision of two pucks on an air table, collisions between spheres of similar and different masses) to test the laws of conservation of momentum and conservation of energy [PR, AI]. (The ontario curriculum,p.201)

**C3.3:**distinguish between elastic and inelastic collisions. (The ontario curriculum,p.201)

**C3.4:**explain the implications of the laws of conservation of energy and conservation of momentum with reference to mechanical systems (e.g., damped harmonic motion in shock absorbers, the impossibility of developing a perpetual motion machine). (The ontario curriculum,p.201)

C3.5: explain how the laws of conservation of energy and conservation of momentum were used to predict the existence and properties of the neutrino
