Speed and Velocity Quiz

shape Introduction

Speed and Velocityis an important topic in General Science. Speed and Velocity Quiz article is exceedingly important for candidates preparing for RRB ALP/Technical Exams/Junior Engineer Recruitment Exams. In this article, candidates can find different types of questions with solution related to the Mass Weight Density topic. The article Speed and Velocity Quiz will assist the students in an understanding of the type of questions expected from the topic Speed Velocity.
Speed is a scalar quantity that refers to "how fast an object is moving. A fast-moving object has a high speed and covers a relatively large distance in a short amount of time.
Velocity is a vector quantity that refers to "the rate at which an object changes its position. When evaluating the velocity of an object, one must keep track of direction. It would not be enough to say that an object has a velocity of 55 mi/hr. One must include direction information in order to fully describe the velocity of the object. For instance, you must describe an object's velocity as being 55 mi/hr, east.
