You are watching: Does the speedometer of a car measure speed or velocity
yes. Velocity is two components (speed and direction). If direction varies while rate is continuous or evil versa, velocity will likewise vary. Ex: car going at consistent speed about a curve, or a carousel
no. Velocity is speed and direction. Due to the fact that speed is a component of velocity, if its speed changes, velocity must also change. Ex: m/s
if one object has a better speed than a 2nd object, go the first necessarily have actually a better acceleration?
no; acceleration is the price of increase/decrease in the velocity of one object. An object as high velocity will have no acceleration if that velocity is no changing. Ex: baseball thrown right into the air
Compare the acceleration the a motorcycle that increases from 80 km/h to 90 km/h v the acceleration that a bicycle that accelerates from rest to 10 km/h in the very same time
both the motorcycle and also the bicycle have the same acceleration (10 km/h). The motorcycle"s higher speed is irrevelant
explain in information the differences between distance and also displacement and also how these terms are related to speed and velocity
-distance is the km or m traveled without regard come direction-displacement is the change in position of a body-speed: street (total time, no direction)-velocity: change in position (delta x) in a given direction/total time
Explain exactly how the same trip, such together a 3 mi operation from her front door to your front door might have an average speed but a zero typical velocity
speed may be continuous but have a zero average velocity due to the fact that there was no adjust in position, the end allude of the 3 mi run was the same position as the start point of the run
acceleration is the rate of adjust of velocityex: a automobile going 15 m/s speeds up for 4 s and also is currently at a brand-new velocity of 20 m/s
change in position of a body. How much a body is from a starting point in a directly line in a offered direction. Supplied when calculating the velocity the a body
