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.

Is a car's speedometer show instantaneous speed average speed or velocity?
It shows instantaneous speed.
How can you show the difference between speed and velocity?
Velocity is speed with direction. To show the difference, show the direction of an object compared with speed alone. For example, a speedometer shows speed alone, a car on a road can show speed and direction.
Does the reading of a speedo meter of a car show the speed or velocity of a car?
Just the speed of the car.
Does the speedometer on a vehicle show the average speed or instantaneous speed?
instantaneous speed.
Does speedometer of a car measures its velocity?
No. The speedometer only displays speed. If it could show your direction at the same time ... like with a gyro-compass or a GPS dial ... then you'd have velocity. Picture four different cars, all moving at 30 miles per hour ... one to the east, one to the west, one north, and one south. All four of their speedometers will display the exact same reading, even though they have four different velocities.

It shows instantaneous speed.

Does the reading of a speedo meter of a car show the speed or velocity of a car?
Just the speed of the car.
Does the speedometer of a car read average speed or instaneous speed?
In a car, the speedometer measured Instantaneous speed. This comes from the assumption that the car does not slow down and speed up fast enough for the speedometer to be able to give an average of the changing speed.
Does the speedometer on a vehicle show the average speed or instantaneous speed?
instantaneous speed.

Can the speedometer of car show the speed in reverse gear?
yes it can
What is different between speed and velocity?
speed is scalar while velocity is a vector. In other words, velocity is to do with direction also. Speed does not show direction.
What does the speedometer in a moving car show you?
It shows the speed and the distance the car travels.
Why does an object moving at a constant speed of 35 mi hr Does not show a change in velocity?
constant speed means no acceleration and thus no change in velocity
What must a displacement always show?
Direction and speed which is also velocity.
Will smaller tires show speed is less the actual?
Yes, it is obvious that if the radius of tire is small than it effect on the speed of the car. Smaller tires will show the speed on the speedometer more than actual.
