Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.

The definition of velocity is the speed of something in a given direction. Therefore it's related to speed.

velocity means speed of an object and in a definite direction.That shows velocity changes with speed

By the speed

The greater the mass of the planet, the greater will be the escape velocity.

No. If the speed varies, the body accelerates, and velocity cannot be constant.

Velocity is the combination of speed and its direction.Any change of speed, or direction, or both, is acceleration.

In common speech, velocity means speed, they are the same thing.

If an object is in motion it has a Velocity, which is speed and direction.

YES!!!!!!!!!!!! A body can have equal velocity and speed at the same time. for suppose a body is travelling at 20m/s in north direction then the speed of the body is also equal to 20m/s. hence speed and velocity are equal in this case.

Momentum is calculated by Mass * Velocity (Speed is the magnitude of Velocity). If velocity increases and mass remains constant, Momentum (measured in kg m/s) increases and if velocity decreases, momentum decreases.

A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.

mass x velocity = momentum. (velocity = speed with a direction)

No. Velocity is speed and direction. If you change either variable, the velocity will no longer be constant.

No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.

No, not at all possible. But constant speed with changing velocity is possible.

No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.

Speed is a scalar, motion (or velocity) is a vector.

Acceleration is the change in velocity ("speed") over time.

The velocity changes. called acceleration.

Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.

they are related by the equation velocity=frequency*wavelength

No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.

Both are velocity functions. Instantaneous velocity is the derivative of the average velocity * * * * * They are both speed functions. Velocity is a vector related to speed but quite irrelevant in this context. An object rotating at a constant [angular] speed has a velocity that is continuously changing but that has no relevance.

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object
