Dimensional motion for ** Master in Physics Solution** is movement of an object in certain planes. Motion in physics can be in one, two or three dimensions.

One dimensional motion for Master in Physics Solution, Engineering in Kenya has more articles.

One dimension in motion means that the body is moving in only one plane and that therefore implies that the body moves in a straight line. If one rolls a marble on a flat surface and in a straight line (not easily done), the marble would be undergoing one dimensional motion as defined in theMaster in Physics Solution program.

There are four acute variables which when put together in an equation describe one dimensional motion. These are;

ü Velocity (V);

- Initial velocity (u)
- Final Velocity (
**v**)

ü Acceleration (**a**)

ü Displacement (**s**) and

ü Time elapsed (**t**).

The equations below show the relationship between these variables in one dimensional motion;

- V
^{2}= u^{2}+ 2as - V = u + at
- S = ut + 1/2 at
^{2} - Average velocity = (v + u)/ 2

With these equations found in the **Master in Physics Solution program**, one can calculate on any form of motion in a straight e.g. the acceleration of a car.

# Two and three dimensional motion for **Master in Physics Solution**

The two forms of dimensional motion in the** Master in Physics Solution program **are better defined when divided into scalar and vector quantities. The difference between scalar and vector quantities as put in the** Master in Physics Solution program is** in the terms ‘magnitude’ and ‘direction’. Magnitude defines how much of the quantity is there. Direction is the way in which a certain magnitude moves. Scalars are physical quantities which are defined by their magnitude only. Scalars include mass, speed, volume, distance etc. Vectors are physical quantities defined by their magnitude and direction. Vectors include velocity, acceleration, force, momentum etc.
