Academic Quotes

The first problem for all of us, men and women, is not to learn, but to unlearn - Gloria Steinem

The act of unlearning is an excellent form of learning. Infact, you will need the skills of unlearning if you intend to become an expert in your desired field.

Do yourself a favor by unlearning, learning and re-learning on a daily basis

If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much - Jim Rohn

There's something special about you. It doesn't matter whether you work for a company or someone; what matters is the amount of investment you've made on yourself.

Investing in yourself is the best life plan you can design for your future

Never underestimate the power of your smile. It can lift up the depressed, improve the mood of the downtrodden and even discourage a suicidal attack. Also remember that your smile makes you more beautiful

Smile always for your own good and the good of others

The only person who is educated is the one who has learned how to learn …and change - Carl Rogers

To perfect your learning process, you must learn, unlearn and re-learn. Infact, we all need to learn how to unlearn those vices we know about ourselves.

Do you know that seeing the devastating consequences of vices (perhaps in movies or real-life) can initiate the unlearning processes in one who does such?

Start where you are. Use what you have. Do what you can - Arthur Ashe

Start now. You've got all it takes to achieve greatness, so no environment can limit you. Just begin something, give in your best and don't stop.

Remember, don't stop giving your best if you truly desire greatness. Nothing can stop you except yourself

Consider this expression below:

A body X exerts a force FX on another body Y. In return, body Y exert a force FY back on body X. The forces FX and FY are equal in magnitude but opposite in direction.

Putting the above expression into equation:

FX = -FY

Where FX is the action force

FY is the reaction Force

The above expression relates to _____.

  • A. Theory of Force
  • B. Force Postulate
  • C. Einstein's proposal on Relativity
  • D. Newton's 1st law of motion
  • E. Newton's 2nd law of motion
  • F. Newton's 3rd law of motion

ANSWER: Newton's 3rd Law of Motion

Newton's 3rd law of motion states that:

To every action, there is an equal and opposite reaction

This law explains what you feel on your hands after hitting a wall with your fist (you applied force to do this). The wall returns an equal and opposite force on your hands; thus the harder you hit, the more pain you feel.

The tendency of a body to remain in a state of rest or in uniform motion is referred to as _____.

  • A. Tension
  • B. Uniform acceleration
  • C. Constant acceleration
  • D. Deceleration
  • E. Inertia
  • F. Velocity

ANSWER: Inertia

Inertia is a property of matter. It was Newton's 1st law of motion the showed the presence of inertia in a body at rest; or in another body moving in a straight line.

The Law of Inertia states that a body at rest will continue in the state of rest while a body in uniform motion will continue in a straight line; unless an external force acts upon it.

Newton's 1st Law of Motion is also referred to as the Law of Inertia

A change in the position of an object with reference to time is best described as _____.

  • A. Momentum
  • B. Displacement
  • C. Velocity
  • D. Acceleration
  • E. Direction
  • F. Motion

ANSWER: Motion

Motion is simply defined as a change in the position of an object with reference to time.

For a body to be in motion, Force must act on it. It was Sir Isaac Newton that explained the relationship between the force(s) acting on a body and the motion of the body.

The saying 'what goes up on earth must come down' can be best attributed to _____.

  • A. Force
  • B. Motion
  • C. Mass
  • D. Acceleration
  • E. Average velocity
  • F. Constant velocity


Force is a push or pull. The force acting on earth (gravitational force) is best attributed for pulling things/object down to earth. It was this that gave rise to the saying: 'What goes up must come down'.

We have _____ laws of Thermodynamics.

  • A. 1
  • B. 2
  • C. 3
  • D. 4
  • E. 5
  • D. 6


There are 4 laws of Thermodynamics numbered from 0 through 3; that is

  • Zeroth Law
  • First Law
  • Second Law
  • Third Law

Which Scientist successfully discovered the theory of special relativity?

  • A. Albert Einstein
  • B. Isaac Newton
  • C. Galileo Galilei
  • D. Neils Bohr
  • E. Ernest Rutherford
  • F. Marie Curie

ANSWER: Albert Einstein

Albert Einstein successfully discovered the theory of special relativity in 1905. In his theory, Einstein determined that:

The laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum does not depend on the motion of all observers.

Generally, the relativity theory is often described with the analogy of a moving car

The scientific study of matter and the movement of matter through space and time is a concept of _____.

  • A. Biology
  • B. Chemistry
  • C. Physics
  • D. Basic Science
  • E. Geography
  • F. Physiology

ANSWER: Physics

By Definition, Physic is the scientific study of matter and the movement of matter through space and time. It further explains how matter interact with each other.
