Linear Motion[edit]
Linear Motion refers to any motion moving in a straight line without changing it's direction
Linear Motion with constant speed over time[edit]
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 t^{2} m Force F m a kg Work W F s kg Pressure P kg Impulse F_{m} F t kg Momentum m_{v} m v kg Energy E = = F v kg
Linear Motion with changing speed over time[edit]
Any Linear Motion travels with different speed at different time v_{1} at t_{1} 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
