An instance of one moving object or person striking violently against another.Elastic collision: An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies after the encounter is equal to their total kinetic energy before the encounter. Elastic collisions occur only if there is no net conversion of kinetic energy into Read more about Collisions[…]


Graphs of simple functions

CONSTANT FUNCTION: Let k be a fixed real number. Then a function f (x) given by f (x) = k for all x ϵ R is called a constant function. Sometimes we also call it the constant function k.IDENTITY FUNCTION: The function defined by I (x) = x for all x ϵ R is called the identity function on R.RECIPROCAL FUNCTION: The function that associates each non-zero real number x to its reciprocal 1/x Read more about Graphs of simple functions[…]
