Chapter 5 Flashcards
What is chemical energy?
Energy contained within the chemical bonds within atoms.
What is efficiency?
The ratio of useful output energy to total input energy.
What is elastic potential energy?
The energy store in an object due to its deformation.
What is electrical potential energy?
Energy of electrical charges due to their position in an electric field.
What is energy?
The capacity for doing work.
What is gravitational potential energy?
Energy of an object due to its position in gravitational field
What is internal energy?
The sum of the random potential and kinetic energies of atoms in a system.
What is kinetic energy?
Energy to the motion of an object with mass.
What is nuclear energy?
Energy within the nuclei of atoms.
What is the principle of conservation of energy?
The total energy of a closed system remains contant,energy cannot be created or detroyed.
What is radiant energy?
Energy associoated with all electromagnetic waves stored within oscillating electric and magnetic fields.
What is sound energy?
Energy of mechanical waves due to the movement of atoms.
What is uniform gravitational field?
A gravitational field in which the field lines are parallel and the value for g remains constant.
