## My Teaching Philosophy.

Teaching is therefore while creative, satisfying and attractive in many respects and suitably rewarding one must be devoted in as many angles as it requires to be successful and responsible keeping the motto of teaching in glaring memory: teaching produces tomorrow’s citizens, the spearheads and pioneers of tomorrow’s world is the just product of today’s education and a teacher is the most relevant architect for that purpose.

I also look at teaching and learning process from another angle of paramount importance. Research. Teaching devoid of the latest knowledge of a body of epistemology, a creative dint of heuristics never discovered before or a suave deviation from a canonical pedagogy cannot be effective or attractive. One therefore in almost all academic branches be inclined to persevere to invent or share such gained insights by others towards the student-body. An ideally inspired student with an appetite to grow and cultivate the action of learning is not only the need of academia but also a cornerstone of a progressive society.

## A Question a Day (series) Q3

The equation v = a*del_t is sometimes used
to find velocity when acceleration and
time are known. Another form of this
equation is v = v_0 + a*del_t. In this second
form of the equation, the function of the
term v_0 is to:

A. indicate that the equation is valid
only for an object that starts at rest.

B. determine the time at which
velocity is equal to zero.

## A Question a Day (series) Q2

1. A ball is thrown with an initial velocity of 20 m/s at an angle of 30°
above the horizontal. What is the instantaneous vertical velocity of
the ball when it is 5.1 m above the release point? (g = 9.8 m/s^2)

A. 0.2 m/s
B. 6.6 m/s
C. 10 m/s
D. 17 m/s
