Tutorial – Work, ** Energy**
(Assume the acceleration due to gravity, g = 9.81 m/s2 )
1. Calculate the work done when a force of 40 N pushes an object a distance of
500 m in the same direction as the force.
2. Calculate the work done when a mass is lifted vertically by a crane to a height of 5 m, the force required to lift the mass being 98 N.
3. A spring, initially in a relaxed state, is extended by 100 mm. Determine the work done by using a work diagram if the spring requires...

Expriment 4: Work, Power and ** Energy**
Department of Math and Physics
College of Science, University of Santo Tomas
Espana, Manila Philippines
Abstract
Two activities were performed in this experiment. For the first activity, the weights of the different members of the group were each computed and were used in order to determine how much work and power each member exerted in climbing up and down the stairs while being timed. From the data obtained, it is apparent that as one is faster...

Light of wavelength 330 nm falling on a piece of metal ejects electrons with sufficient
** energy** which requires voltage V0 to prevent a electron from reading collector. In the same
setup, light of wavelength 220 nm, ejects electrons which require twice the voltage V0 to
stop them in reaching a collector. Find the numerical value of voltage V0...

Holt Physics—Chapter 5: Work and ** Energy** Price
I. Section 5.1—Work
A. Definition of work
1. Work does not mean the same thing in Physics as it does in the everyday sense of the word.
2. Work is defined as a force causing a displacement.
Work = force x displacement
W = Fd
3. Work is NOT done on an object unless the displacement is greater than zero
4. The only forces that are considered to do work are those that...
