# 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...
