[01] Classical Mechanics

Question 1

What does Classical Mechanics study?

Answer 1

Motion of bodies under the influence of forces

Question 2

Does Classical Mechanics require quantum or relativistic considerations?

Answer 2

No

Question 3

List the main topics of study in Classical Mechanics

Answer 3

• Newton’s laws of motion
• Work and energy
• Rotational motion
• Principles of conservation

Question 4

What are Newton’s laws of motion?

Answer 4

• An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force (First Law)
• Force is equal to the change in momentum per change in time (Second Law)
• For every action, there is an equal and opposite reaction (Third Law)

Question 5

What does the concept of work and energy in Classical Mechanics refer to?

Answer 5

• Work → force done on an object to move it a certain distance
• Energy → the ability to do work or cause change

Question 6

Describe the concept of rotational motion in Classical Mechanics

Answer 6

The movement of an object in a circular path around a central point

Question 7

What are the principles of conservation in Classical Mechanics?

Answer 7

• Conservation of energy → energy cannot be created or destroyed, only transferred or transformed
• Conservation of momentum → total momentum of a system remains constant unless acted upon by an external force
