Does a cars speedometer measure the speed or the velocity of an object?
Shiraem1
A car's speedometer measures the vehicle's speed.
Speed is a scalar unit that only accounts for rate of movement (Example: 50 meters/second).
Velocity is a vector unit that accounts for rate anddirection of movement (Example: 50 meters/second to the south).

The car's speedometer reads the same number whether you're driving north, east,
south, or west. But all of those are different 'velocities', since the direction of motion
is an essential component of velocity.
The speedometer doesn't display any information regarding the direction you're going.
It displays only the 'magnitude' of the velocity, which is the speed.

Does a speedometer both measure speed and velocity?
No. A speedometer only measures speed. You also need a position sensor or direction vector coupled with the speedometer in order to know velocity, because velocity includes direction.
What is the difference velocity and speed?
speed is the measure of an object
What type of velocity does the speedometer on a car measure?
It reads instantaneous speed, and tells you nothing about average speed.
What describes an object and speed and direction?
As regards a moving object, we call the measure of the speed and direction it is moving its velocity.
How can you measure when an object has reached terminal velocity?
the terminal velocity is the total speed that its take an object to reach the point it required from the initial velocity

Why do you measure bowler's throwing ball as speed but not velocity?
Speed and Velocity are the same thing, it is a measure of rate of change of position of an object.

Does the speedometerof a car read average speed or instantaneous speed?
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
Does a cars speedometer measure speed or velocity or both?
Yes it does, it measures miles per hour (mph) and kilometers per hour (kph), which is basically your speed. Some cars have speedometers that go up to a higher or lower speed, but don't worry about that. Also there tends to be more kilometers per hour than miles per hour on any given speedometer.
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.
What is the difference between an object's speed and a object's velocity?
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
