Study Notes
Classical Mechanics - Lecture 1
- Classical mechanics describes the motion of macroscopic objects.
- Abstract methods were developed leading to the reformulations of classical mechanics, like Lagrangian Mechanics and Hamiltonian Mechanics.
- The quantitative measure of inertia of a body is mass.
- Gravity is a branch of physics describing conditions of rest or motion of material bodies under the action of forces.
- The mass that determines the acceleration of a body under the action of a given force is inertial mass.
- A particle is an object which has mass, but no size.
- Newton's 1st law of motion is applicable for free particles.
- There are 3 degrees of freedom for a thing moving in space.
- Work done by external force in an N-particle system is known as virtual work.
- Total virtual work done on an N-particle system.
Classical Mechanics - Lecture 2
- The conditions which restrict the motion of a system are called constraints.
- The number of independent ways in which a mechanical system can move without violating any constraint is the degrees of freedom.
- A thing moving in space has 3 degrees of freedom.
- Work done by external force in an N-particle system is known as work.
- Total virtual work done on an N-particle system.
