What is derivational and inflectional affixes?

Derivational affixes create new words. Inflectional affixes create new forms of the same word. Derivational is an adjective that refers to the formation of a new word from another word through derivational affixes.

Which morphemes are derivational?

In grammar, a derivational morpheme is an affix—a group of letters added before the beginning (prefix) or after the end (suffix)—of a root or base word to create a new word or a new form of an existing word.

How to do a one dimensional elastic collision?

One Dimensional Elastic Collisions | Academo.org – Free, interactive, education. A demonstration of one dimensional elastic collisions highlighting the conservation of both momentum and energy Imagine two billiard balls of mass m 1 and m 2, travelling at velocities v 1 i → and v 2 i → respectively (the i stands for initial).

How is the elastic collision equation derived in Socratic Form?

Collisions are called elastic collisions if, in addition to momentum conservation, kinetic energy remain conserved too. To derive the elastic collision equations we make use of the Momentum Conservation condition and Kinetic Energy Conservation condition. m1(v1i − v1f) = m2(v2f − v2i) …………… ( 1 )

How to calculate elastic velocities in one dimension?

Thus, 1 2m1v12 + 1 2m2v22 = 1 2m1v’12 + 1 2m2v’22(two-object elastic collision) 1 2 m 1 v 1 2 + 1 2 m 2 v 2 2 = 1 2 m 1 v ′ 1 2 + 1 2 m 2 v ′ 2 2 ( two-object elastic collision) expresses the equation for conservation of internal kinetic energy in a one-dimensional collision. Example 1. Calculating Velocities Following an Elastic Collision

What happens when velocity v and M 1 collide?

A particle of mass m 1 and velocity v collides elastically (in one dimension) with a stationary particle of mass m 2. What are the velocities of m 1 and m 2 after the collision?
