What Are The Kinematic Formulas?

What Are The Kinematic Formulas? Kinematic Equations: The goal of this first unit of The Physics Classroom has been to investigate the variety of means by which the motion of objects can be described. The variety of representations that we have investigated includes verbal representations, pictorial representations, numerical representations, and graphical representations (position-time graphs and velocity-time graphs). In Lesson […]

What Is An Oral Fixation?

What Is An Oral Fixation? Oral Fixation: The oral stage, spanning from birth to 21 months, is when the infant’s pleasure centers are situated around the lips and the mouth. The first ‘love-object’ of this stage is the mother’s breast, where libidinal gratification is first granted in the pleasures of feeding. Enjoyment is further sought in […]

What is a Nucleolus Function?

What is a Nucleolus Function? Nucleolus Function: The nucleolus is a round body located inside the nucleus of a eukaryotic cell. It is not surrounded by a membrane but sits in the nucleus. The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of […]

Oir Past Tense Conjugation

Oir Past Tense Conjugation Oír Conjugation: You’re probably hearing lots of different sounds right now, but if you’re paying attention to what you’re reading, you might not be aware of them. You might be hearing the traffic, a car horn or someone talking on the radio or TV, or if you’re lucky enough to be […]

What Are Alphanumeric Characters?

What Are Alphanumeric Characters? Alphanumeric Characters: Since computers (or central processing units, to be specific) use machine language in the form of numbers to communicate, computer programmers need to write their instructions using numbers rather than alphabet characters. To do this, programmers use numeric representations of what humans see as alphabet characters. You’ve probably seen […]

Perfect Square Trinomial Formula

Perfect Square Trinomial Formula Perfect Square Trinomial: There is one “special” factoring type that can actually be done using the usual methods for factoring, but, for whatever reason, many texts and instructors make a big deal of treating this case separately. “Perfect square trinomials” are quadratics which are the results of squaring binomials. (Remember that “trinomial” means […]

Dormir Preterite Conjugation

Dormir Preterite Conjugation Dormir Conjugation: In general, in order to use a Spanish verb in a sentence you must change the ending of the verb to correspond with the subject. We call this conjugation. If you think of a verb as a power tool like a drill, that has different bits at the end that you […]

How To Calculate The Angular Velocity Formula

How To Calculate The Angular Velocity Formula Angular Velocity Formula: n physics, angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time. There are two types of angular velocity: orbital angular velocity and spin angular velocity. Spin angular velocity […]

Primary Somatosensory Cortex

Primary Somatosensory Cortex Somatosensory Cortex: The primary somatosensory cortex is located in the postcentral gyrus, and is part of the somatosensory system. It was initially defined from surface stimulation studies of Wilder Penfield, and parallel surface potential studies of Bard, Woolsey, and Marshall. Although initially defined to be roughly the same as Brodmann areas 3, 1 and 2, more recent work […]

Average and Instantaneous Rate of Change

Average and Instantaneous Rate of Change Instantaneous Rate Of Change: We see changes around us everywhere. When we project a ball upwards, its position changes with respect to time and its velocity changes as its position changes. The height of a person changes with time. The prices of stocks and options change with time. The […]
