Physics Formulas: Mechanics Mechanics is the oldest branch of physics. Mechanics deals with all kinds and complexities of motion. It includes various techniques‚ which can simplify the solution of a mechanical problem. Here are some of the often required physics formulas falling in mechanics domain. Motion in One Dimension The physics formulas for motion in one dimension (Also called Kinematical equations of motion) are as follows. (Here ’u’ is initial velocity‚ ’v’ is final velocity‚ ’a’ is

Title: Forces Table Introduction: The purpose of this week’s lab‚ titled “Forces Table”‚ was to look at vectors in two dimensions. The lab was also used to help up understand how to sum up forces and the decomposition. In our experiment‚ we had to estimate a third force that would balance out our other two. This would then make the sum of the forces zero. To calculate our forces we used Newton’s Second Law below: (1) In the above equation‚ the ƩF represents the sum of all of the forces in Newton’s

The Physics 500 Introduction: The purpose of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the

Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field (p. 576). Just from this definition‚ it is clear that numerous physics concepts can be used to help explain why electrophoresis works. First‚ I will discuss charge and electric fields and how these principles are utilized in gel electrophoresis. This will be followed by a

because their velocities will the larger and will need a larger force to go downwards. Air resistance of an object is affected by its mass‚ the total surface area that is exposed by the air resistance‚ and how fast an object is falling. When an object is falling‚ the force diagram will be represented by the force of air of an object pointing upwards and the force of gravity pointing downwards. But the value of the force of air and the force of gravity will not be the same in the beginning of the fall

Force is required to produce motion in a body. Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real
