...because velocity is a vector quantity, which means that it includes both the magnitude and the direction of motion.
The speedometer only measures the speed of the car and not its velocity. Speed is a scalar quantity, which means that it only indicates magnitude and not direction of the motion. Thus, the speedometer only shows the distance covered by the car with time (speed), but it does not indicate if the car is moving forward, backward, left or right.
Here is the difference between contact forces and non-contact forces:
Contact forces are forces that result from two objects coming into physical contact with each other. Non-contact forces are forces that result from the interaction of objects that are not in contact with each other.
Of the gravitational pull and other things like mass. Planet earth it,s self as you said sir.
