Classical Mechanics Quiz Explanations
1. Law of inertia was proposed by Galileo Galilei which states that the body which is at rest will remain at rest and the body in constant motion wil remain in constant motion unless an external force is applied on the body.
2. According to Newton’s second law of motion, time rate of change of momentum is equal to force applied on the body.
F = dp/dt
3. 1 newton = 1 kg. m/s2
= 103g . 102cm/s2
= 105 dyne
So, 1 dyne = 10-5 newton
4. Momentum is a vector quantity as it contains in itself the term “velocity”, which is also a vector quantity.
5. Fermi-Dirac statistics are for fermions which behave in the realm of quantum mechanics. Check it here
Bose Einstein statistics is applicable for bosons (also in the quantum mechanics realm)
So, Maxwell-Boltzmann statistics is the one that is applicable for classical particles.
