Velocity is a vector, speed is a scalar

[CC007]

Describe the bug The name of the Velocity class is incorrect. Since it is implemented like a scalar, the name should be Speed. Velocity should refer to a vector, eg a speed in a certain direction.

To Reproduce Steps to reproduce the behavior:

• Write the expression 100 mph or 100 km/h
• Assign the expression to a variable

Expected behavior The variable should be of type Speed, however it is of type Velocity

Hi @CC007. Good point! However, the SI unit for velocity is m/s, the directional part is considered “understood.” This is standard nomenclature in physics, which is the context for this library.

If the directional attribute is significant in the calculations, manifold-science provides vector support. For instance, check out VelocityVector.
