EXPERIMENT #5
WORK AND ENERGY
Abstract
In this experiment, the defender intends to fathom and gain data on work and energy. The advocate will discuss the central
concentrations and mathematical definition that are needed to know to ceaselessly get the data on the thoughts and association of
work and energy. Besides, the advocate means to coordinate those ideas and demonstrate genuine circumstances and exercises
that portrays the idea of work and energy just as protection of energy. Besides, the advocate will execute the strategies and
methodology that are should have been done to accomplish the goal of this test with the use of the exercises that are on the given
connections, furthermore, the defender will utilize work and energy test system. Likewise, those methodology will be executed as
appropriately as workable for the defender to acquire possible outcomes. Hence, the defender will talk about every one of the
outcomes procured in each system of the examination. Finally, the advocate will make an inference on the ideas of work and energy
saw in the test.

,I. Introduction
Naturally, work alludes to how hard a movement is. Therefore, characterizing how people assign their energy in doing such
works. Be that as it may, in Physics, it is work is characterized as the scalar result of the power applied by a framework to another
framework and the uprooting of the item which the power was applied to. Work can be written mathematically as:
𝑊 = 𝐹𝑜𝑟𝑐𝑒 ∙ 𝑑𝑖𝑠𝑝𝑙𝑎𝑐𝑒𝑚𝑒𝑛𝑡
People consistently display the Physics meaning of work through day by day exercises. These exercises incorporate
however not restricted to pushing a container on a level, non-frictionless plane; pushing a case on a calculated plane; pulling a
weight up and lifting a hefty carton. Work having a couple of vector amounts doesn't make it a vector amount itself, since work is
the speck result of the power and the uprooting of the framework, thus, it is a scalar amount. The justification this is that the work
done can be positive, negative, or zero, in any case, the signs doesn't characterize the bearing of the work yet rather changes on
the edge of reference of the spectator..
Another idea that is basic in Physics is the idea of energy. Energy in Physics is characterized as the ability to manage job.
One can relate it in financial terms, on the off chance that cash can purchase stuff and one doesn't have cash, one can't accepting
stuff. Also, perhaps the most crucial laws in Physics in regards to energy is the second law of thermodynamics, which expresses
that energy can nor be made nor annihilated yet it must be changed starting with one structure then onto the next. This marvel is
handily found in day by day exercises, for example, an apple tumbling from a tree (potential to dynamic); vehicle running with the
assistance of its engine and gas (substance to mechanical to active energy), and so forth Energy is characterized numerically as:
1
𝐾𝐸 = 𝑚𝑣 2
2
Where m = mass of the object
v = velocity of the object
2|Page
, These two concepts were introduced in this experiment such that these concepts exhibit a relation, in which work is also
defined as the change in kinetic energy. This relation is defined mathematically as:
1 1
𝑊 = ∆𝐾𝐸 = 𝐾𝐸𝑓 − 𝐾𝐸𝑖 = 𝑚𝑣𝑓 2 − 𝑚𝑣𝑖 2
2 2
Henceforth, this test is finished by the advocate with the sole motivation behind getting the authority on the idea of work
and energy just as their connection to one another. In addition, the motivation behind this analysis is to acquire information about
the marvel that happens in each framework that goes through work and encounters motor energies just as the changes.
Objectives of this Activity:
1. To describe the conditions under which positive and negative work are done and to use the work equation to calculate
the amount of work done.
2. To define potential energy, to identify the two forms and the variables that affect the amount of each form, and to calculate
the potential energy possessed by an object.
3. To define the kinetic energy, to identify the variables that affect the amount, and to calculate the kinetic energy possessed
by an object.
4. To identify the two forms of mechanical energy, to distinguish between mechanical and non-mechanical energy, to
describe the relationship between mechanical energy and work, and to relate the total mechanical energy to the amounts of kinetic
energy and potential energy.
5. To distinguish between power and work and to use two power equations to calculate power.
6. To determine the effect of the angle of an inclined plane upon the amount of force and the amount of work done when
pulling a cart up an inclined plane at a constant speed and to the same height.
7. To observe the effect of original car speed upon the skid distance.
8. To investigate energy relationships for a roller coaster car.
