A car accelerates uniformly from 18 km h–1 to 36 km h–1 in 5 s. Calculate (i) the acceleration and (ii) the distance covered by the car in that time.
Initial velocity (u) = 18 km/h Final velocity (v) = 36 km/h
A train starting from rest attains a velocity of 72 km h–1 in 5 minutes. Assuming that the acceleration is uniform, find (i) the acceleration and (ii) the distance travelled by the train for attaining this velocity.
Initial velocity (u) = 0 m/s Final velocity (V) = 72 km/h
WHAT IS LIBRARY SCIENCE
Information studies is another name for the academic field of library science. This field emphasises the value of preserving knowledge and increasing literacy and focuses on how to identify and use data or things.
Library Catalogues: Objectives
Introduction Library catalogue is a complete, organized record of a library’s contents which refers to: a. maps b. periodical archives c. artwork d. computer files e. microfilm f. books. Library catalogues are limited to a particular library or a single group of libraries, but nearly all library catalogues today share the same basic search features …
EQUATION FOR POSITION–VELOCITY RELATION
From the velocity-time graph shown in figure , the distance s travelled by the object in time t, moving under uniform accelerationa is given by the area enclosed within the trapezium OABC under the graph.
EQUATION FOR POSITION-TIME RELATION
Let us consider that the object has travelled a distance s in time t under uniform acceleration a. In Following figure , the distance travelled by the object is obtained by the area enclosed within OABC under the velocity-time graph AB. Thus, the distance s travelled by the object is given bys = area OABC …
EQUATION FOR VELOCITY-TIME RELATION or , First equation of Motion by Graphical method.
EQUATION FOR VELOCITY-TIME RELATION Consider the velocity-time graph of an object that moves under uniform acceleration as shown in the following Fig., but now with u ≠ 0). From this graph, you can see that initial velocity of the object is u (at point A) and then it increases to v (at point B) in …

VELOCITY-TIME GRAPHS
The three equations of motion will be used to create velocity-time graphs. Case 1: Velocity-time graphs with constant velocity (zero acceleration)When the velocity is constant, the velocity-time graph, with Y-axis denoting velocity and the X-axis denoting time, will be like: As the graph shows, the velocity is constant (c) throughout the interval.No matter how much …
