power factor improvement methods for the energy conservation in drives

Power Factor is defined as the ratio of working or useful power to the apparent power.

More the Power Factor, more the device is energy efficient.

hence, these are the power factor improvement methods for the energy conservation in drives.

What are the methods of energy conservation in electrical
drives

Discuss the disadvantages of having low power factor and discuss
the various methods of power factor improvement.

Just before striking the ground, a 2.0kg mass has 400J of kinetic energy. If friction can be ignored, from what height was it dropped?(g = 9.8m/s2)

A
brief summary about:
Newton’s laws
Friction and circular movement
Work-energy(kinetic and potential)-power-and conservation of
energy
Fluid( pascal’s law,buyoant force,Archimedes principle, fluid
flow and viscosity and bernoulli’s equation)

2.
Describe Kinetic Energy and Potential Energy. Describe the Law on
Conservation of Mechanical Energy. If an object that is thrown
perpendicular to the ground by neglecting the friction is required
to go up to 125 m height, what should be the initial velocity of
the object? Take the acceleration of gravity 10 m / s and assume
that the mass of the object does not change.

- In your own words, explain potential energy, kinetic energy,
conservation of energy and examples in daily life.
- In your own words, explain the definition of work in
Physics.
- In your own words, explain Hooke's Law and elastic potential
energy.

Power Factor Code Arduino
Develop a Power factor Program in C and upload it into
your Arduino
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

3. a)What is kinetic energy? b) What is potential energy? c) What is the law of conservation of energy 4. a)What is momentum? b) What is the law of conservation of momentum?

Could some give a deep descripition about the power
factor.
1. How the power factor will be less?
2.What should we do inorder to increase the power factor?
3.How do we maintain a good power factor in a 3 phase motor without
using the capacitor?

Explain conservation of mechanical energy (including formula) in
terms of potential and kinetic energy using an example in your
sport
