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

Linear Motion with changing speed over time[edit]

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
