A vector can be represented by a line segment ... Vectors are equal if they have the same magnitude and direction regardless of where they are. Triangle ABC is isosceles. X is the midpoint of ...

Speed is a scalar quantity. That means it only has a value, not a direction. Velocity is the rate of movement in a specific ...

A streamline is a line that is tangential to the instantaneous velocity direction (velocity is a vector, and it has a magnitude and a direction). To visualize this in a flow, we could imagine the ...

G-fields are vector fields—which means they have both magnitude and direction—that explain how space is influenced by an object. Bianconi uses the G-field as what is known as a Lagrangian ...

The result is a single number—a scalar (not a vector). It has magnitude, but not direction. That’s key. This scalar doesn’t tell us where to go next, it tells us how strongly this particular ...
