CBSE Class 11-science Physics Motion in a Straight Line
Displacement and VelocityDistance: Total path length covered during a given time interval.
Displacement:: Shortest straight line distance between the initial and final position.
Average speed: Total distance travelled divided by the total time taken.
Average velocity: Total displacement divided by total time taken.
Graphical RepresentationAverage velocity = Slope of the line connecting the initial and final positions corresponding to that interval on x-t graph.
The area under the velocity-time curve = Displacement of the object during that interval of time.
Instantaneous velocity is the slope of the distance time graph taken at that instant.
Kinematics of Linear MotionIdentify and derive the equations of kinematics for body along straight line motion with constant acceleration.
