Speed and velocity always have the same magnitude, because

speed is the magnitude of velocity.

The difference is that velocity has a direction but speed doesn't

How is velocity same from instantaneous speed?

Instantaneous speed is the magnitude of the velocity. Velocity also states the [direction] of the speed.


Can average velocity and average speed be same?

The magnitude of both can be the same.


Is it possible for the speed to increase at the same time the velocity decreases?

Velocity being a vector, it is tricky to say that "velocity increases or decreases". Its magnitude might decrease - but its magnitude is, precisely, the speed.


Is the magnitude of speed always the same as the magnitude of velocity... yes or no can you please also explain your answer using relevant principles of physics?

Yes, the magnitude of speed is the same as the magnitude of velocity. Velocity V= s(R/r)= sR' where s is the speed and R'=(R/r) is the unit vector in the direction R, where R is a position vector and r is the magnitude of R. So "s' is the magnitude (scalar) of the velocity. In Physics, a rotating object can have constant speed and changing direction. A car can have the same speed on the speedometer and experience a force as it turns at the this constant speed. The turning creates a force as there is acceleration caused by the change in velocity, in this case the change in direction, not the change in speed..


How can an object stay at same speed and still be accelerating?

acceleration is change in velocity over time. It is important to know that speed is not a vector quantity; it is scalar (meaning it does not have direction), -- velocity does. Therefore, speed is only the MAGNITUDE of velocity. Also, acceleration is a vector quantity meaning it has both magnitude and direction. If you change EITHER magnitude or DIRECTION, acceleration changes. Okay anyway to answer your question, You can have the same magnitude of velocity (aka same speed) and still be accelerating if YOU CHANGE DIRECTION. --- gh

Are speed and acceleration the same?

No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.


Can average velocity and average speed be same?

The magnitude of both can be the same.


Is overall velocity the same as average speed?

No, velocity is a vector quantity (i.e. magnitude & direction) while speed is a scalar quantity (i.e. magnitude only).

Is the velocity of one car traveling 40 km per hour east the same as a car traveling 40 km per hour south?

No. The speed is the same, the velocity is not. The term "velocity" includes the indication of the direction. Two velocities are the same if they have the same magnitude (e.g., both are 40 km/hour), AND the same direction.No. The speed is the same, the velocity is not.

Can an object have a constant spped and velocity at the same time?

Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.


What is an angular speed of a rotating body?

Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).


What is used for finding the velocity of a moving vehicle?

A "radar gun" is used by police to know the speed of fast moving vehicles. Velocity is a vector. That means it has magnitude and direction. Its magnitude is same as speed.
