Work, Energy, and Power 3.3 Flashcards
The formula for work done
W=Fx
Energy is the…
Capacity to do work
Kinetic energy is energy due to…
motion of an object with mass
Gravitational potential energy is the energy…
of an object due to its position in a gravitational field
Chemical energy is the energy…
contained within the chemical bonds between atoms, released when atoms are rearranged.
Elastic potential energy is the energy…
stored in an object as a result of reversible change in its shape
Nuclear energy is the energy…
within the nuclei of atoms, released when subatomic particles are rearranged
Radiant (or electromagnetic) energy is the energy…
associated with all electromagnetic waves, stored within the oscillating elctric and magnetic fields
Sound energy is the energy…
of mechanical waves due to the movement of atoms
Internal (heat or thermal) energy is..
the sum of the randomly distributed potential and kinetic energies of the molecules or particles in a substance/system
The principle of conservation of energy.
states that the total energy of a closed system remains constant: energy can never be created or destroyed, but he can be transferred from one form to another.
Define power.
The rate of work done
All equations for Power
E=Pt
W=Pt
P=Fv
Define the work done by a force
The work done by a force is defined as the product of the magnitude of the force and the distance moved by the object in the direction of the force.
Electric potential is the energy of…
charges due to their position in an electric field
