< Physics Course | Motion

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

## Linear Motion with constant speed over time

editAny 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 Distance m Speed Accelleration Force kg Work kg Energy kg

## Linear Motion with changing speed over time

editAny 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
