Kinematics

1. Definition An object is said to have variable speed (or non-uniform speed) if it covers unequal distances in equal…

1. Introduction Average speed is defined as the total distance travelled divided by the total time taken. It provides a

1. Introduction Velocity is defined as the rate of change of displacement of a body with respect to time. It

Let us considered a train moving with a constant velocity of say 15m/s along a straight track so as to

To study the position-time graph of the uniform motion, let us again consider the example of a train moving along

1. Introduction When a body moves with variable acceleration, the acceleration can change at every moment of time. The Instantaneous

1. Introduction The first equation of motion describes the relationship between an object’s initial velocity, final velocity, acceleration, and time

1. Introduction The second equation of motion relates the displacement of an object to its initial velocity, time, and uniform

1. Introduction The third equation of motion relates the square of the final velocity ([v]) of a uniformly accelerated object

When a baseball is hit by a bat, what determine where the baseball land? How do you describe the motion
