IDEAL FLUIDS- is said to be ideal when it cannot be compressed JOULES- is a derived unit of energy in the International System
and the viscosity doesn’t fall in the category of an ideal fluid. of Units . It is equal to the energy transferred to (or work done
on) an object when a force of one newton acts on that object in
IDEAL GAS LAW- the law that the product of the pressure and
the volume of one gram molecule of an ideal gas is equal to the the direction of the force's motion through a distance of one
product of the absolute temperature of the gas and the universal metre (1 newton metre or N⋅m).

gas constant. JOULES PER SECOND- is a unit of action or of angular
momentum. The joule-second also appears in quantum
IMPULSE- equals the force applied multiplied by the time it was
applied. mechanics within the definition of Planck's constant. Angular
momentum is the product of an object’s moment of inertia, in
INELASTIC COLLISION- a collision in which the total kinetic units of kg⋅m 2 and its angular velocity in units of rad⋅s −1.
energy of the colliding bodies or particles is not the same after
the collision as it was before (opposed to elastic collision).

INERTIA- is a quality of all objects made of matter that possess
mass. They keep doing what they are doing until a force changes
their speed or direction.
INTETNSITY- is the power transferred per unit area, where the
area is measured on the plane perpendicular to the direction of
propagation of the energy.

INTERFERENCE- the net effect of the combination of two or

more wave trains moving on intersecting or coincident paths.
INTERNAL FORCE- is the energy contained within it. It is the
energy necessary to create or prepare the system in any given
internal state. It is the energy necessary to create or prepare
the system in any given internal state.
