Motion Theory[edit]
Motion refers to the movement of an object from one position to another position
If there is a Force F that makes an object of Mass m to move a Distance s within Time t Then the motion can be characterized by
Speed[edit]
 The ratio of Distance over Time gives Speed of Motion
Acceleration[edit]
 The ratio of Speed over time gives Acceleration of the motion
Distance[edit]
 Distance travels of the motion is defined as the product of Mass times Acceleration
 S = v t = a t^{2}
Force[edit]
 Force causing the Motion
 F = m a = m v / t = p / t
Work Done[edit]
 Work done by the force is the product of the Force and the Distance travel
 W = F s F v t = p v
Energy[edit]
 Work done by the force is the product of the Force and the Distance travel
Linear Motion[edit]
Linear Motion is any motion moving in a straight line without changing it's direction . For instance, Linear Motion with constant speed over time , linear Motion with changing speed over time
Linear Motion with constant speed over time[edit]
For any Linear Motion that has constant speed at all time can be expressed as
 v(t) = V
Linear Motion with changing speed over time[edit]
For any Linear Motion travels with different speed at different time v_{1} at t_{1} and v at t
 The Change in Speed . ∆v =
 The Change in Time . ∆t =
 The ratio of Change in Speed over Change in Time gives the Accelerarion of the motion
 a = ∆v / ∆t =
 ∆v = a ∆t
 v(t) = a t if ∆v = v , ∆t = t

 a =

 a = 0 . Linear motion with constant velocity
 a > 0 . Linear motion with increasing velocity
 a < 0 . Linear motion with decreasing velocity
Non  Linear Motion[edit]
For any Non linear motion v(t) that does not travel in a straight line with changing direction
