a car speedometer actions speed, not velocity. you should recognize the direction the auto is traveling in order 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 2 parts (speed and direction). if direction varies while rate is consistent or vice versa, velocity will certainly likewise differ. ex: automobile going at continuous speed roughly a curve, or a carousel
no. velocity is rate and direction. considering that speed is a component of velocity, if its rate transforms, velocity must additionally adjust. ex: m/s
if one object has a greater rate than a second object, does the 1st necessarily have actually a higher acceleration?
no; acceleration is the rate of increase/decrease in the velocity of a things. An object as high velocity will certainly have no acceleration if its velocity is not altering. ex: baseball thrown right into the air
Compare the acceleration of a motorcycle that accelerates from 80 km/h to 90 km/h with the acceleration of a bicycle that increases from remainder to 10 km/h in the same time
both the motorcycle and also the bicycle have the exact same acceleration (10 km/h). the motorcycle"s higher speed is irrevelant
define in information the differences between distance and displacement and exactly how these terms are related to speed and also velocity
-distance is the km or m traveled without regard to direction-displacement is the adjust in place of a body-speed: distance (full time, no direction)-velocity: change in position (delta x) in a offered direction/total time
Explain how the exact same expedition, such as a 3 mi run from your front door to your front door might have an average rate yet a zero average velocity
speed may be consistent yet have a zero average velocity because tbelow was no adjust in position, the finish suggest of the 3 mi run was the exact same place as the start allude of that run
acceleration is the rate of adjust of velocityex: a automobile going 15 m/s increases for 4 s and also is currently at a brand-new velocity of 20 m/s
readjust in position of a body. just how far a body is from a starting suggest in a straight line in a offered direction. used once calculating the velocity of a body
