## 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
