Motion in a Straight Line

Frame of reference, Motion in a straight line: Position-time graph, speed and velocity. Elementary concepts of differentiation and integration for describing motion, uniform and nonuniform motion, average speed and instantaneous velocity, uniformly accelerated motion, velocity - time and position-time graphs. Relations for uniformly accelerated motion (graphical treatment).

Kinematic Equations of Motion

For objects in uniformly accelerated rectilinear motion, the five quantities, displacement x, the time took t, initial velocity v0, final velocity v and acceleration...

Acceleration

The time rate of change of velocity is called acceleration. Its unit is m/s2. Its dimensional formula is . It is a vector quantity. Acceleration can...

Velocity

The rate of change of displacement of an object in a particular direction is called its velocity. Its unit is m/s. Its dimensional formula is...

Speed

The time rate of change of position of the object in any direction is called the speed of the object. Its unit is m/s. It...

Motion

"An object is said to be in motion if its position changes with time". The concept of motion is a re’ live one and a...
