Centripetal and centrifugal force.

Hello guys,
This post is for the school students in their secondary school or high school.You must have come across these terms in your physics books.Both of them are often confusing to understand.Well I will clear confusion once and for all.Centripetal force is the force acting towards the centre for an object in circular motion.It always acts towards the centre.Centrifugal force is the force acting away from centre for an object in circular motion.Examples-
1.A stone tied to a thread when rotated has a force towards the centre which helps it to rotate.
2.Inside a washing machine clothes are whirled away from centre.This is centrifugal force.
Actualy whenever centripetal force will be there there will be centrifugal force.Now the question is if both of them occur then why centripetal force is considered real and centrifugal pseudo.This is because the motion is accelerating leading to non Newtonian frame of reference or non inertial frame of reference.Therefore centrifugal has been wrongly discriminated as pseudo or fictitious.In reality both of them occur.
Thanks...

Sci-fi WH

Hey all,  Consider two points A and B separated at a distance of say 5 cm in a piece of paper. If you were to reach point B from A you need to cover 5cm distance. But what if you wrap the paper in such a way that point A and B intersect. Then it becomes a shortcut right. This is exactly the concept behind worm holes. Due to the fabric nature of space-time this can be assumed that we can enter from past to future and vice versa through these holes known as worm holes created due to rupture in space time fabric due to movement of celestial bodies including planets. Time is a man made straight dimension but in our universe time is not moving forward rather everything is happening at the moment. It is like a 3hrs Bollywood movie being watched in a DVD where the time period for movie or event is fixed and we can go backwards and forward. Similarly events occuring in universe are fixed and we can rewind or move ahead using worm holes.  This concept is hypothetical based on journals ...

Twin Paradox

Hey there,  It's been long I haven't written anything but today I chose to pen-down something very close to my heart, the twin paradox. It was taught to us in 1st semester in physics under the topic special theory of relativity. The story is as under..  There were two twins A and B. They celebrated their birthday on same date every year. But on their 18th birthday A went for a space trip to rotate around a celestial object with a speed nearly 80% of light. He told his brother B that he would come back next year on their birthday when they would be celebrating their 19th birthday. He went for the trip with speed of 0.8c to space and took exactly 1year to return on earth. As he returned he found his brother B was 80 years old. Why this paradox took place? It's because earth revolved 62 years during this time as compared to A's spaceship which took only one year as it was travelling at very high speed. This is a time travel which can occur according to special theory of re...

Importance of units

Hello all, Welcome back... In today's blog I am going to discuss about the importance of units.We are taught right from childhood that a physical quantity consists of two parts,one being magnitude and other being unit.To specify a physical unit we need both.For eg if someone asks you how much distance did you cover in today's morning walk?You might say 2km.Imagine if you would have said only 2,was it explainable.Answer is no.Similarly only saying km will also not be explainable.That is why both magnitude and units are important.Now this information you will get in primary textbooks also.But can you imagine its practical implications and its repercussions.Let me tell you a story. But before that I would like to emphasize on the importance of SI units.SI units are international standard units designed to maintain uniformity.Imagine what will happen if we neglect its importance.Now here comes a real life story. An aeroplane flew from its source towards it's destination,b...
