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

to Newton’s first law of motion‚ an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. It is the natural way for objects to keep on doing what they’re doing or keep going the same direction. All objects resist changes in their state of motion. In the absence of an unbalanced force‚ an object in motion will maintain its state of motion. This is often called the law of inertia. The law of inertia is most commonly experienced when

endurance is also reffered to as stamina or aerobic fitness. 2. Muscular Strength Muscular strength is the ability of a muscle or group of muscles to exert a force against a resistance in a single contraction. Strength is fundamental for all sports 3. Muscular Endurance Muscular endurance is the ability of a muscle to exert a force repeatedly over an extended period of time. 4. Flexibility Flexibility is the capacity of a joint or joints to move through a full range of motions‚ or the

When tubing is bent to a specific shape or geometry‚ force must be applied so as to exceed the materials ’yield point’‚ which is the material’s capability to resist permanent deformation‚ while staying below the material’s ’ultimate tensile strength’‚ which is the limit of the material’s ability to resist tearing. As the tube is bent over a specific radius the outside wall will stretch in tension while the inside wall bends under compressive forces. The boundary line through the centre of the tube

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the

as oscillatory motion in which the resultant force on the oscillating body at any instant is directly proportional to its displacement from the rest position and opposite in direction to its motion. For a spring system‚ this can be written as F = -kx where F is the resultant force on the object attached to the spring‚ x is the displacement of the object from equilibrium and k is a constant called the spring constant. The force is a restoring force because it tends to restore the object back to
