## Classical Mechanics MCQs | MSc Physics

**Classical Mechanics MCQs** | MSc Physics: Here you will learn the MCQs of classical physics. Different chapters kinematics, Newtonian Mechanics, Newton equations of motion. Lagrangian formulation of mechanics. Hamiltonian formulation of mechanics. The motion under central forces. Harmoni oscillator, Coupled oscillations, and normal coordinates. Non-linear oscillations. Collision and scatterings. Motion in non-inertial systems. The motion of Rigid bodies. The special theory of relativity. Newtonian Gravity and Newton cosmology. Hamiltonian Jacobi theory of dynamics. In MSc Classical Mechanics MCQs you will also cover the following topics vectors, linear motion, two-dimensional motion, Newtons’ laws of motion. Momentum, Energy and work, Harmonic motion, collisions, etc.

# If the length of a simple pendulum is reduced to half and mass is doubled then the time period of simple is

- Remains unchanged
- Halved
- Doubled
- Decreased by a factor of

# The center of mass of velocity is defined by

# A bob of mass m is moving in XY-plane as a simple pendulum. Its Lagrangian function is:

# The moment of inertia of a uniform rigid rod of length L and mass M about an axis perpendicular to the rod and passing through its center of mass is

# A body traveling initially at 5 ms^{-1} is accelerated in the direction of motion at 2 ms^{-2} for 10 seconds. The distance it travels in this period of time in meters is

- 150 meters
- 100 meters
- 75 meters
- 50 meters
- 25 meters

# A planet has a period of revolution about the sun equal to T and a mean distance from the sun equal to R, T varies directly as

- R
- 1/R
- R
^{2} - R

# The product of generalized coordinate and its conjugate momentum has the dimension of

- force
- energy
- linear momentum
**angular momentum**

# The dimensions of generalized momentum

- are always those of linear momentum
- are always those of angular momentum
- may be those of linear momentum
- may be those of angular momentum
**both C and D**

# If the Lagrangian does not depend on time explicitly

**the Hamiltonian is constant**- the Hamiltonian can not be constant
- the kinetic energy is constant
- the potential energy is constant
- none of the above
