Question

a) Is the Monte Carlo require force calculation to do the calculations?

b) In the conventional Monte Carlo calculations, is it required to compute forces?

c) What is the differences between Monte Carlo simulation and molecular dynamics simulation?

d) Is the values differences of mechanical and non-mechanical properties by using Monte Carlo or Molecular dynamics?

Answer #1

a) No, the Monte Carlo calculations are used for broad algorithms, and it does not required to calculate each forces, what is requires is general force computational, or the force function.

b) Yes, in the conventional Monte Carlo calculations, the computation of forces is required to run the monte Carlo algorithm/calculations.

c) Monte Carlo simulations are the numerical results of the randomness, while the molecular dynamics posses direct result of calculations with given parameters.

d) If the iteration or system has less variable than only value can be different, but if the system is complex and have large variable than both calculation results similar, and only difference is Monte Carlo computes much faster than molecular dynamics methods.

Upvote, if the answer was helpful. Thanks and have a nice & safe day.

A Monte Carlo simulation is a method for finding a value that is
difficult to compute by performing many random experiments. For
example, suppose we wanted to estimate π to within a certain
accuracy. We could do so by randomly (and independently) sampling n
points from the unit square and counting how many of them are
inside the unit circle (assuming that the probability of selecting
a point in a given region is proportional to the area of the
region)....

You are using a rope to pull a box across a hardwood floor at
constant speed.
a) Is the box in mechanical equilibrium? Explain.
b) Is the box accelerating? How do you know?
c) The mass of the box is 14 kg. The normal force exerted on the
box by the ground is 120 N, and the friction force between the box
and the floor is 20 N. What is the tension in the rope?
d) Sketch a force diagram...

Why do credit card companies typically require small minimum
payment amounts on their customers’ monthly credit card statements.
a. Credit card companies are concerned that their customers
will be put in financial distress if required to make higher
payments.
b. Credit card companies want to promote faster repayment, and
customers will be encouraged to pay more each month if they’re able
to pay well beyond the minimum.
c. Credit card companies want to increase profits by promoting
slower repayment,...

Lab 1 Part 2 One dimensional Motion Two groups of scientists are
testing the force of a spring. Your job is to determine if this
data is equivalent, and what are the statistical differences
between the two groups. Calculate the initial velocity as the
object leaves the spring. WHAT IS THE TITLE OF THIS LAB, understand
what that means. Use on the data from each group, do not grab
information from the other groups experiment, none, not a single
parameter....
