a auto speedometer measures speed, no velocity. You need to recognize the direction the automobile is traveling in stimulate to measure the velocity, and also a speedometer does not measure the direction of travel

You are watching: Does a car speedometer measure velocity

yes. Velocity is two parts (speed and also direction). If direction varies while rate is continuous or vice versa, velocity will also vary. Ex: auto going at continuous speed approximately a curve, or a carousel
no. Velocity is speed and direction. Due to the fact that speed is a component of velocity, if its rate changes, velocity must also change. Ex: m/s
if one object has a better speed 보다 a second object, walk the 1st necessarily have a higher acceleration?
no; acceleration is the price of increase/decrease in the velocity of an object. An item as high velocity will have actually no acceleration if that velocity is not changing. Ex: baseball thrown right into the air
Compare the acceleration of a motorcycle that speeds up from 80 km/h to 90 km/h with the acceleration the a bike that increases from remainder to 10 km/h in the exact same time
both the motorcycle and the bicycle have actually the very same acceleration (10 km/h). The motorcycle"s higher speed is irrevelant
explain in detail the differences in between distance and displacement and how this terms are related to speed and also velocity
-distance is the km or m traveled there is no regard to direction-displacement is the readjust in position of a body-speed: street (total time, no direction)-velocity: change in place (delta x) in a given direction/total time
Explain exactly how the very same trip, such as a 3 mi run from her front door to your front door might have an median speed however a zero average velocity
speed might be continuous but have actually a zero mean velocity because there was no adjust in position, the end suggest of the 3 mi run was the same position as the start allude of the run
acceleration is the price of adjust of velocityex: a auto going 15 m/s increases for 4 s and also is now at a new velocity that 20 m/s
change in position of a body. How much a body is from a starting point in a directly line in a given direction. Provided when calculating the velocity that a body
