Linear MotionEdit

Linear Motion refers to any motion moving in a straight line without changing it's direction

Linear Motion with constant speed over timeEdit

Any Linear Motion that has constant speed at all time can be expressed as

v(t) = V

For any motion travels a Distance in Time caused by a Force has the following characters

Characteristics Symbol Mathematic Formula Unit
Speed v   = a t  
Accelleration a   =    
Distance s v t = a t2 m
Force F m a kg  
Work W F s kg  
Pressure P   kg  
Impulse Fm F t kg  
Momentum mv m v kg  
Energy E   =   = F v kg  

Linear Motion with changing speed over timeEdit

Any Linear Motion travels with different speed at different time v1 at t1 and v at t

The Change in Speed


The Change in Time


The ratio of Change in Speed over Change in Time gives the Accelerarion of the motion
