Q&A

Is speed an absolute or relative concept?

Speed is a relative concept that is measured with respect to a reference point.

Can speed be additive or subtractive?

Yes, speed can be additive or subtractive depending on the relative motion of objects.

What is constant velocity motion?

Constant velocity motion is when an object maintains a fixed speed and direction.

Is constant velocity motion detectable?

No, constant velocity motion is completely subjective and undetectable.

Who first described the concept of being at rest in motion?

The concept of being at rest in motion was first described by Galileo.
