Ionic Compounds

What are they?

To answer this, we must go back and ask, why to atoms form molecules? The answer is, they all wish they were noble gases! Noble gases have their outer, or valence, electron shells completely full, which makes them so perfect, they don't need to interact with anything.

Grade 11 Physics

Kinematics

Kinematics is all about motion. Motion is a change in position relative to a frame of reference

Vocabulary

scalar vs vector distance vs displacement speed vs velocity frame of reference acceleration

Vectors

Vectors can be manipulated in two ways, by trigonometry or on a Cartesian coordinate system

The four kinemetic equations

$$d = v_it + \frac{1}{2}at^2$$ $$v_f^2 = v_i^2 + 2ad$$ $$v_f = v_i + at$$ $$d = \frac{v_i + v_f}{2}t$$
