How is velocity different than speed and what are the key distinctions between the two?
Velocity is a vector quantity that includes both speed and direction, while speed is a scalar quantity that only measures how fast an object is moving. The key distinction between velocity and speed is that velocity includes direction, while speed does not.
How matter waves are greater than the velocity of light?
There are some situations in which waves move faster than the speed of light; but in no case can this be used to transmit matter, energy, or information, at a speed faster than the speed of light in a vacuum.
If air resistance is negligible then terminal velocity is the velocity of shock waves?
No, terminal velocity is the constant speed that a freely falling object eventually reaches when the upward force of air resistance equals the downward force of gravity. Shock waves are rapid changes in air pressure and temperature produced by an object moving faster than the speed of sound in a particular medium.
If the final velocity will be less than initial velocity the object is increasing speed or decreasing speed?
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
Are wave speeds dependent on material?
Yes. The velocity of mechanical (a.k.a. acoustic) waves is determined by the mass density, elasticity (stiffness), and intrinsic stress of the material. The velocity of electromagnet waves (e.g. light or radio waves) is determined by the electrical permittivity and magnetic permeability of the material.
What does velocity include that makes it different than speed?
direction
Why the velocity x rays is less than the speed of light?
It isn't - at least, not in a vacuum. All electromagnetic waves have the same speed in the vacuum. Both visible light and x-rays are electromagnetic waves.

Is the velocity of light more than velocity of radio waves?
No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
Is the formula for velocity different than the formula for speed?
The size of the velocity is the speed, and you calculate it the same way. But whenyou find the size of the velocity, you're not done yet, because you also need itsdirection.

Can a particle in one dimensional motion have less speed than velocity?
Speed and velocity cannot be compared because they are different things. It is like saying "apples > oranges". Velocity is a vector and, as such, it has a direction and a size. The size of the vector velocity is it's speed.To answer your question: no because they can't be compared. And if you wanted to ask if the size of the velocity vector being smaller than the speed... no... that is the definition of speed... so it cannot be different, regardless of the number of dimensions you are using.

What is the rate of change in position or rate of motion?
Velocity, which is different than speed in that it has a directional component to it.
What is the rate of motion or the rate of change in position?
Velocity, which is different than speed in that it has a directional component to it.

Velocity, which is different than speed in that it has a directional component to it.
What is the rate of change position or rate of motion?
