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

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..


Is speed similar to velocity?

Speed and velocity are related concepts but not the same. Speed is the rate at which an object moves, while velocity includes both the speed and direction of motion. Velocity is a vector quantity, which means it has both magnitude and direction, while speed is a scalar quantity with only magnitude.


When do the velocity and speed of a moving body become equal?

The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.


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


How is velocity same from instantaneous speed?

Velocity is a vector quantity that includes both speed and direction, while instantaneous speed is the magnitude of velocity at a specific moment in time without considering direction. In other words, velocity accounts for the object's motion in a specific direction, whereas instantaneous speed is the rate at which an object is moving at a given instant, regardless of direction.

Does average velocity and average speed have the same number?

velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.


Are speed and acceleration the same?

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

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).


When is speed equal to the magnitude of velocity?

Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.

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.

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.


Explain the difference between velocity and speed?

Velocity includes both speed (magnitude of the velocity) and direction, while speed is just the magnitude of the velocity without any indication of direction. So velocity is a vector quantity, whereas speed is a scalar quantity.
