Cricket Writer Weekend Quiz – June 3rd 2017
The 5-part Answer to the questions set by Quiz Master Rohit Beri are as follows:
1. Angular Momentum (This question was specifically asking about how ball moves in the air. While
“Energy” makes the ball move, Angular Momentum defines how it moves in the air after leaving the
2. Spin bowling makes use of angular momentum
3. Magnus Effect. It is the force exerted on a rapidly spinning cylinder or sphere moving through air or
another fluid in a direction at an angle to the axis of spin. This force is responsible for the swerving of
balls when hit or thrown with spin. Note: Bernoulli’s principle works on the pressure differential and
plays a role in swing balls.
4. Heinrich Gustav Magnus, a German Physicist, studied this effect in detail and thus the effect is
named after him.
5. Pressure Difference causes ball to swing.
This was a tough quiz! But as cricket fanatics (thats pretty much all of us here at Cricket Writer!) its very
interesting indeed to learn the science behind the sport that we all love. Atul Kumar put in
another brilliant effort to 3 of the answers correct and the Quiz Master Rohit Beri has decided he
indeed deserves the prize.
Congrats again Atul – you get to be Quiz Master (again!) on www.cricketwriter.com anyweek you choose

We put up a quiz every Saturday which will
stay up for 48-hours or when the right answer
The is posted in the comments section. Either
way,the question stays up at least for 24-
The Winner will be invited to send in their
own Weekly Quiz question to the Cricket

Quiz Question for Weekend of 3rd June 2017
This weekend we have a completely unique
quiz that combines Cricket and Physics –
one which will tax your brains and your
knowledge. To win the Quiz, you have to
answer it correctly and in full. All 5 parts need
to be correct to win the prize. Needless to say,
the decision of the Quizmaster is final!
The question this week is contributed by a very
keen supporter of Cricket Writer, Rohit Beri,
who is as passionate about Physics as he is
about Cricket. Today, he asks some questions
about the physics of the art of Bowling!
Answer all 5 questions below correctly to win the prize:
1. What is the conserved quantity (physics)
that play a critical role in how the ball moves
in the air after leaving the bowler’s arm but
before reaching the batsman?
2. Which kind of bowling makes use of the
same (conserved quantity) more often, Swing
3. What is the technical name of the above
4. Name of the scientist after whom the effect
is named and his country?
5. What is the name for Physical force what
causes the other type of the effect i.e. Spin or
Swing as the case maybe?
Go for it folks! Clear the cobwebs in your mind
and shake up your school physics memories to
answer Rohit’s challenge! And have a lot of fun
while you do that!
