when you know both speed and direction of an objects motion you know the velocity of an object.
v = d/t
its changed the world in speed and volocity
the speed the wave travels threw space
Speed only tells how fast something is going, while velocity tells speed and direction.
speed = distance/time = 100mi/2h = 50mi/h
If you observe a clock moving past you at the speed of light, it will appear to you to have stopped.
The name fastpitch was first brought up by how their arm circulated in speed. The movement from distance to the given object is determined by calculating the volocity of movement from one given object to the next. And in baseball the given objects would be the pitchers hand and the baseball bat at specific heights and speeds.
No, the mass of an object does not affect the speed at which it falls to Earth. All objects fall at the same rate of acceleration due to gravity, regardless of their mass. This principle is known as the equivalence principle.
Speed is a scalar quantity that describes how fast an object is moving regardless of its direction, while velocity is a vector quantity that describes both the speed and direction of an object's motion. Speed is expressed as a magnitude only, whereas velocity includes both magnitude and direction.
The speed varies according to the refractive index of the objects.

Different objects can have different speeds; also, the same object can have one speed now, and a different speed later.
