Nat Sci 1 Prelim Exam Coverage

What will be included in Prelim Exam are the following

  • Brief History of Physics

[The arrangement of the following is based on Conceptual physical science by Paul G. Hewitt, John Suchocki, Leslie A. Hewitt. -- 5th ed. Chapters 1, 2, 3 and 4.
For other earlier edition (like the one I'm using in class), the same topics runs from Chapters 1, 2, 3, 4, and 5]
  •  Aristotle on Motion 
  •  Galileo’s Concept of Inertia 
  •  Mass—A Measure of Inertia 
  •  Net Force 
  •  The Equilibrium Rule 
  •  Support Force 
  •  Dynamic Equilibrium 
  •  The Force of Friction 
  •  Speed and Velocity 
  •  Acceleration 

  •  Newton’s First Law of Motion 
  •  Newton’s Second Law of Motion 
  • When Acceleration Is g—Free Fall 
  •  Forces and Interactions 
  •  Newton’s Third Law of Motion 


  • Momentum and Impulse 
  • Impulse Changes Momentum 
  • Conservation of Momentum 
  • Collisions 
  • Energy and Work 
  • Potential Energy 
  • Kinetic Energy 
  • Work–Energy Theorem 
  • Conservation of Energy 
  • Power 


  • The Universal Law of Gravity 
  • The Universal Gravitational Constant, G
  • The Inverse-Square Law 
  • Wei ght a nd Wei ght lessness 
  • Universal Gravitation 
  • Projectile Motion 
  • Fast-Moving Projectiles—Satellites 
  • Circular Satellite Orbits 
  •  Elliptical Orbits 
  •  Escape Speed 

It is my regret to inform you that the report of Group 1 (Sources of Energy) will not be included in Prelim Exam. If you have already studied it, please do not be disheartened for it will be incorporated in the Midterm Exam. My apology for this abrupt change.

Type of Exam: Multiple Choices
Although it is Multiple choices, conceptual and problem-solving questions are merged in it as well.
34 % of all the questions are objective
Ex: This quantity refers to the product of mass of an object and its velocity.
A. force
B. acceleration
C. impulse
D. momentum
33 % will be composed of conceptual questions.
Ex: Can an object possess work?
A. Yes
B. No

And the remaining 33 % will be problem solving questions
Ex: A 0.1-kg stone is dropped from the roof of a building. It strikes the ground after 6 s. How high is the building? Air friction can be neglected. (Note: For simple calculations, use g≅10 m/s2) 
A. 20 m
B. 400 m
C. 2 m
D. 10 m
E. none of the above.

Please study well and...
Good luck, guys!
