Mixing of the scalar gt (assuming it is mean zero) can be quantified using a negative Sobolev norm. Commonly chosen is the H − 1 norm ‖gt‖H − 1: = ‖( − Δ) − 1 / 2gt‖L2, which essentially measures the average filamentation width, though ... WebTranscript. Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity. Created by Sal Khan.
