Speed is a scalar quantity that represents the magnitude of velocity, which is a vector quantity. Velocity includes both the speed and direction of an object's motion. Consequently, when discussing the speed of a car, we are only concerned with the magnitude of its velocity, not its direction.
What else can I help you with?
How is the velocity of a car different from its speed?
The velocity of a car includes both its speed and its direction of motion, while speed is simply the magnitude of the velocity without considering direction. Velocity is a vector quantity, meaning it has both magnitude and direction, whereas speed is a scalar quantity, only representing the magnitude of motion.
Does the reading of the speedometer of a car show the speed or velocity of the car?
The speed of the car. The speed-o-meter only shows a magnitude ( or a number ) and to tell the velocity of a car it would have to give that speed some direction. Since the speedometer assigns no direction to the car, the number assigned as the speed of the car cannot be the velocity of the car.
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed 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..
The car rounds the turn at a constant velocity of 90 mph?
If the car rounds the turn, then its velocity is not constant.Velocity is a thing that has magnitude and direction. The magnitude is what we call "speed".If the direction is changing, then the velocity is changing, even if the speed is constant.

Velocity is a vector quantity, meaning it has both magnitude and direction, whereas speed is a scalar quantity, only representing the magnitude of motion.
How is speed difrent from velocity?
Velocity has magnitude and direction and speed only has magnitude.
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.

The speed of the car. The speed-o-meter only shows a magnitude ( or a number ) and to tell the velocity of a car it would have to give that speed some direction. Since the speedometer assigns no direction to the car, the number assigned as the speed of the car cannot be the velocity of the car.
How is velocity diffrent from speed?
Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.

What acceleration of a car accelerate even thought your speed don't change?
If the car is moving at a constant speed but is changing direction, it is accelerating. Acceleration is change in velocity, and velocity includes magnitude (speed) and direction.
The car rounds the turn at a constant velocity of 90 mph?
If the car rounds the turn, then its velocity is not constant.Velocity is a thing that has magnitude and direction. The magnitude is what we call "speed".If the direction is changing, then the velocity is changing, even if the speed is constant.
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.
How is velocity and speed different?
Velocity has a direction.
Explain how velocity differs from speed?
Velocity includes not only the speed of an object but also its direction of motion. Speed is scalar quantity, meaning it only considers magnitude, while velocity is a vector quantity that requires both magnitude and direction.
