conservation of dissipation of energy Flashcards
how can energy be transferred?
By radiation, by heating, also by an electrical current.
What are the stores of energy?
magnetic. internal (thermal) chemical. kinetic. electrostatic. elastic potential. gravitational potential. nuclear.
what energy gets transfers occur when something in dropped?
It will start with gravitational potential energy and then get converted to kinetic energy.
What is the principle of energy conservation?
The principle of energy of conservation is that energy is neither created or destroyed. It will transform from one type to another.
What is a closed system?
A closed system is a physical system that does not allow transfer of matter in or out of the system, though, in different contexts, such as physics, chemistry or engineering, the transfer of energy is or is not allowed.

What energy transfers occur when a pendulum moves?
As a pendulum swings, its potential energy converts to kinetic and back to potential.
What is work done equal to?
work done is equal to energy transferred.
How do you calculate work done?
work done = force x distance
How is the work done to overcome friction transferred?
What happens to the gravitational potential energy stores of an object as it
moves up and down?
The object’s energy is slowly transferred from the kinetic store to the gravitational potential store as it slows down and climbs higher. Once the object reaches its highest point, all of its energy is in the gravitational potential store.
