Physical Education plays a significant role in imparting knowledge about body motion and methods to enhance flexibility, subsequently benefiting an individual’s mental and physical capabilities.

Here you will find case study based questions for class 12 physical education Chapter 8 Biomechanics and Sports.

Biomechanics and Sports Case Study Questions

Case Study Question 1:

Friction is both an advantage and a disadvantage in sports.
(a) What is friction? How many types of friction are there?
(b) How is friction an advantage in sports and where is it practically applied?
(c) What disadvantage does friction offer to a sportsperson? Explain using a few examples.

Ans. (a) Friction is the force that resists the relative motion between two surfaces. There are two types of friction, namely static and dynamic. Static friction keeps the object at rest while dynamic friction occurs when the two objects are moving.
(b) Friction is of advantage at many places in sports. Using spikes in footwear in sports like football and cricket helps use friction as a stabilising force. Gymnasts and carom players use dusting powders to generate friction to optimise performance and improve control. Similarly, badminton rackets have rough grip to improve hold.
(c) Friction is disadvantageous in sports like cycling and car racing. More the friction, more is the effort required to generate speed. Too much friction can cause tyres to burst during car racing and cause accidents. Skiers also slow down because of friction, thus hampering their speed.

Case Study Question 2:

Abhishek, the Class 12 monitor, was asked to speak on different types of movements possible in human body and their importance.
(a) How many basic types of movements would Abhishek talk about?
(b) What movements that he demonstrated were possible at the shoulder joint?
(c) He demonstrated dorsiflexion and plantar flexion movements. At what joints do these take place and what do these terms mean?

Ans. (a) Abhishek would have talked about the four basic movements, namely flexion, extension, abduction and adduction. Rest of the movements at different joints are combinations of these four basic movements.
(b) The movement that Abhishek would have specifically demonstrated at the shoulder is called circumduction where the shoulder swings through a 360 degree circle. This is the maximum range of movement possible at any joint.
(c) Dorsiflexion and plantar flexion are movements that take place especially at the ankle joint. While in dorsiflexion, the ankle moves upwards towards the body; in plantar flexion, the ankle moves towards the ground.

Case Study Question 3:

While talking about Newton’s laws of motion and their application in sports, a Physical Education teacher gave examples from cycling, swimming and cricket.
(a) How many laws did Newton describe?
(b) What law applies to cyclists and how?
(c) What law is in force when the swimmer pushes off the wall of the swimming pool to start the race?
(d) What law is in play when the ball is hit by the batsman?

Ans. (a) Newton described three laws.
(b) Cyclists use the first law of motion, also known as the law of inertia. While cycling, the cyclists only move when they start to pedal and stop only when they apply brakes.
(c) While pushing against the wall of the swimming pool, the swimmer brings into play the second law of motion, also known as the law of acceleration. This permits the swimmers to use the wall of the pool to generate the force needed to take off.
(d) Newton’s third law, namely the law of reaction, is used by batsmen as they offer opposition to an incoming ball by using the bat to hit it in the opposite direction.

Important Points About Case-Based Questions in Physical Education Class 12:

• Case-based questions hold a weightage of around 15 to 20% in the 2022-23 examination cycle.
• These questions revolve around everyday life scenarios and require thorough reading of the provided passage.
• They cover various units prescribed by CBSE for Physical Education, demanding complete knowledge of the syllabus.
• When approached with the right mindset, case-based questions can be the highest scoring part of the examination.
• CBSE plans to increase the weightage of such questions in the future.

Key Instructions for Preparing for Case-Based Questions:

• It is crucial for students to read the passage in-depth before attempting the questions.
• Students must prepare well for these questions as they demand complete knowledge of the various concepts in the syllabus.
• These questions are centered around everyday life, making them relevant to students’ understanding of the subject matter.
• CBSE intends to further increase the weightage of such questions in the upcoming years.
• Proper preparation for case-based questions can significantly impact a student’s performance in the Physical Education board exam.

Case Study Question Format for Physical Education

In the CBSE board examinations for class 12, the questions pertaining to Physical Education have historically come in two distinct types: objective and subjective.

However, the latest circular issued by CBSE for the 2022-23 academic session has introduced a significant change. CBSE has explicitly indicated that competency-based questions, including case studies, will be distinct from subjective questions. It’s now highly likely that CBSE will exclusively present objective questions in the CBSE class 12 Physical Education case study section.

Types of CBSE Class 12 Physical Education Case Study Questions:

• Historically, CBSE class 12 Physical Education exams have featured two types of questions: objective and subjective.
• Objective questions typically involve selecting the correct answer from multiple options.
• Subjective questions require students to provide detailed, written responses.
• However, recent changes suggest that CBSE may now focus primarily on objective questions in the case study section.

Benefits of Studying Physical Education:

• Physical Education education provides insights into body motion and techniques to enhance flexibility.
• Improved flexibility contributes to enhanced mental and physical abilities.
• This subject empowers individuals to lead healthier lives through informed choices.
• It fosters an understanding of the importance of physical well-being.

Preparation Tips for Class 12 Physical Education Case Study Questions

To excel in class 12 Physical Education board exams, it’s essential for students to prepare thoroughly for case-based questions. Here are some straightforward tips to tackle them effectively:

1. Carefully read the given text.
2. Understand the situation and pay attention to the question.
3. Analyze before crafting your response.
4. Practice extensively.
