Overview When a set of forces act on an object in such a way that the lines of action of the forces pass through a common point‚ the forces are described as concurrent forces. When these forces lie in the same geometric plane‚ the forces are also described as coplanar forces. A single G G equivalent force known as the resultant force FR may replace a set of concurrent forces F1 and G F2 ‚ as shown. This resultant force is obtained by a process of vector addition of the original force vectors and produces

people are forced to undertake a difficult change in their lives. This is evident in the feature article Paul de Gelder composed by Caitlin Chang where various language and visual techniques have been combined to portray how events can effect and force upon change in an individual’s life. Throughout the article‚ first person point of view “I” has been used and repeated to assist readers in understanding de Gelder’s life and issues he has had to face along the way. It also provides readers with

Friction Introduction The amount of friction force between two surfaces in contact depends on the type of the surfaces in contact and the amount of compression between the surfaces. Static friction is the force that is acting against your force before the object begins to move. If you exert a small push on the box‚ the box will not move because static friction is directly opposite to the push. If you apply a greater force than the static friction force‚ the friction increases to match the magnitude

brutal tendencies‚ often towards traitors within their own ranks. So this kind of brutality was true of both the Bolsheviks and their opposition‚ which means that it was not really an advantage for the Bolsheviks‚ just another tactic employed by all forces; hence it was not a significant reason for the Bolsheviks remaining in power. A temporary policy of the Bolsheviks that incorporated many

A projectile is an object upon which the only force acting is gravity. Many projectiles not only undergo a vertical motion‚ but also undergo a horizontal motion. That is‚ as they move upward or downward they are also moving horizontally. There are the two components of the projectile’s motion - horizontal and vertical motion. And since perpendicular components of motion are independent of each other‚ these two components of motion can be discussed separately. The goal of this part of the lesson is

increase in a normal force‚ there will be a corresponding increase in friction. Introduction: Force is usually connected with a push or pull exerted on an object. In this experiment‚ I am using a contact force‚ a force that exists from physical contact between two things. I am pulling the spring scale‚ which measure force in Newtons (kg x m/s2)‚ and then the block is moving. Different masses (kg)‚ or the measure of the resistance of an object to changes in its motion due to a force‚ of an object
