An object starts at position 12 on a horizontal line with a reference point of 0. What is the position of the object if it moves 14 units to the left?

A spacetime diagram is a graphical illustration of the properties of space and time in the special theory of relativity.Spacetime diagrams allow a qualitative understanding of the corresponding phenomena like time dilation and length contraction without mathematical equations.. The history of an object s location throughout all time traces out a line referred to as the object s world line in ...

A clock position or clock bearing is the direction of an object observed from a vehicle typically a vessel or an aircraft relative to the orientation of the vehicle to the observer. The vehicle must be considered to have a front a back a left side and a right side. These quarters may have specialized names such as bow and stern for a vessel or nose and tail for an aircraft.

Rotation around a fixed axis is a special case of rotational motion. The fixed-axis hypothesis excludes the possibility of an axis changing its orientation and cannot describe such phenomena as wobbling or precession.According to Euler's rotation theorem simultaneous rotation along a number of stationary axes at the same time is impossible; if two rotations are forced at the same time a new ...

An incremental encoder will immediately report changes in position which is an essential capability in some applications. However it does not report or keep track of absolute position . As a result the mechanical system monitored by an incremental encoder may have to be homed (moved to a fixed reference point ) to initialize absolute position measurements.

In navigation dead reckoning is the process of c...
