Newtonian Mechanics and relativistic mechanics




#1. According to Newton's First Law of Motion, an object will remain at rest unless:

#2. Newton's Second Law relates force, mass, and acceleration. The formula representing this law is:

#3. In Newton's Third Law, when you sit in a chair, your weight is the action force. What is the reaction force?

#4. If you double the force applied to an object of constant mass, what happens to its acceleration?

#5. Which of Newton's laws explains why a rocket moves forward as exhaust gases are expelled backward?

#6. In circular motion, the force directed toward the center of the circle is called:

#7. The gravitational force between two objects depends on:

#8. If an object is in equilibrium, the net force acting on it is:

#9. According to Newton's Law of Universal Gravitation, the force between two masses is directly proportional to the:

#10. When a net external force is applied to an object, what happens to its momentum?

#11. Which of Newton's laws is often summarized as "For every action, there is an equal and opposite reaction"?

#12. Special Relativity was introduced by:

#13. Accrding to Special Relativity, as an object with mass approaches the speed of light, its relativistic mass:

#14. The equation E=mc2 relates:

#15. In Special Relativity, time dilation occurs when:

#16. The Lorentz contraction refers to the:

#17. The speed of light-c is approximately:

#18. According to Special Relativity, mass and energy are interchangeable, as expressed by:

#19. As an object with mass approaches the speed of light, its momentum:

#20. In relativistic mechanics, what happens to an object's length as its velocity approaches the speed of light?
