3.1. Momentum and Newton’s laws of...

recall F = ma and solve problems using it, understanding that acceleration and resultant force are always in the same direction

15. Ideal gases

15.3. Kinetic theory of gases

explain how molecular movement causes the pressure exerted by a gas and derive and use the relationship pV = ⅓Nm < c² >, where < c² > is the mean-square speed (a simple model considering one-dimensional collisions and then extending to three dimensions using ⅓ < c² > = < cx² > is sufficient)

3. Dynamics

3.3. Linear momentum and its conser...

apply the principle of conservation of momentum to solve simple problems, including elastic and inelastic interactions between objects in both one and two dimensions (knowledge of the concept of coefficient of restitution is not required)
