physics notes on motion

MOTION 

DEFINITION: Motion is the change in position of an object due to applied force with time.
 CLASSES OF MOTION
* Kinematics
* Dynamics
KINEMATICS : Is the study of motion without the force that causes it.
DYNAMICS : Is the study of motion and the force that causes it.
TYPES OF MOTION 
* Rotational motion
* Random motion
* Rectilinear / Translational motion
* Oscillatory / Vibrational motion
ROTATIONAL MOTION 
   Is the motion of a body round a circular path from a fixed point.
Examples :
* motion of fan blades
* motion of car tyres
* motion of Earth round its axis.
* motion of  electrons of atom round the orbit.
* motion of car wheel.
