Module 9 Flashcards
is a word that tends to be used in everyday life.
Energy
can be defined as the ability to do
work (work being the exertion of a force through a distance).
Energy
2 types of energy?
Kinetic and potential energy
2 Types of potential energy?
gravitational potential energy
elastic potential energy
is a potential energy stored
in an object due to its location from the reference level.
Gravitational potential energy (GPE)
What is the formula for the gravitational potential energy?
W=mgh= GPE
is an energy that is stored due to deformation by an elastic object; for example,
stretching a spring.
Elastic potential energy (EPE)
is energy in motion.
Kinetic energy (KE)
What is the formula for kinetic energy?
KE= 1/2 mv^2
What is the formula for elastic potential energy?
EPE= 1/2 kx^2
where:
k- spring constant
x- extension or compression of spring

In physics, work and energy are two quantities which are associated. In the absence of energy, there will be no
work done also. Energy is defined as __________ . . In fact, the amount of work done by the
force is equal to the change in energy. Mathematically, we can write the equation ___________ .
the ability to do work
W=ΔPE=ΔKE=ΔEPE
