force acting on a moving body is constant in magnitude and direction, the amount of work done is defined as the product of just two factors: the component of the force in the direction of motion, and the distance moved by the point of application of the force. Thus the defining equation...
Both gravity and an elastic spring are conservative forces. As shown here, the work done by conservative forces can be easily calculated, without having to evaluate the integral in the above equation. Work Done On A Rigid Body To determine the work done by a force on a rigid body we must...
I look on that man as happy who, when there is a question of success, looks into his work for a reply. Ralph Waldo Emerson Tweet More quotes about: purpose work happiness success The heights by great men reached and kept were not attained by sudden flight, but they while their ...
Theoretical determinations are mostly based on the hypothesis that the initial perturbation of the orbital of interaction species, determines the process of a reaction or an interaction. In the equation of this state, the development of perturbation theory was studied by Hudson and Klopman [29]. ...

Although in the real world we would have to account for the force of friction between the block and the surface on which it is resting, we ignore friction here and assume the block is resting on a frictionless surface. When the spring is at its natural length (at rest), the system is...
Equation (1) is estimated first on the pooled sample including both females and males, and then separately for females and males.Footnote 12 4.2 Pooled results Table 4 shows estimates of Eq. (1) for the pooled sample of females and males. Column (1) shows results for paid work time, ...
Whenever a force acts on a body and the body undergoes a displacement in the direction of the force, then work is said to be done. Workdone=Force×displacementWorkdone=Torque×angulardisplacement The unit of work depends upon the unit of force and displacement In the SI system of units, th...

So the relationship between kinetic energy can be summed up as Work done by forces acting on a body = change of kinetic energy in the body Equation 3.5 This is sometimes known as the work-energy theorem. Worked examp .4 A car of mass 1000 kg travelling at 30m/s has its speed reduced...
