Q1. What is the primary focus of sports physics?
- A. The history of sports
- B. The application of physics principles to sports ✓
- C. The rules and regulations of sports
- D. The psychology of athletes
Why: Sports physics applies principles of physics to understand and improve athletic performance.
Q2. Which of the following is a fundamental concept in sports physics?
- A. Economics
- B. Kinematics ✓
- C. Literature
- D. Music
Why: Kinematics is the study of motion and is a key concept in sports physics.
Q3. What force is responsible for keeping a ball in the air when it is thrown?
- A. Friction
- B. Gravity ✓
- C. Magnetism
- D. Electrostatic force
Why: Gravity is the force that pulls objects toward the Earth, keeping the ball in the air until it lands.
Q4. Which of the following is an example of projectile motion in sports?
- A. Swimming laps
- B. Throwing a javelin ✓
- C. Cycling on a track
- D. Running on a treadmill
Why: Projectile motion occurs when an object is thrown or launched, such as a javelin in javelin throwing.
Q5. What is the term for the path an object follows through the air?
- A. Trajectory ✓
- B. Velocity
- C. Acceleration
- D. Inertia
Why: Trajectory refers to the curved path an object follows when it is thrown or projected through the air.

Q1. What is the primary force responsible for propelling a sprinter forward during a race?
- A. Friction ✓
- B. Thrust
- C. Gravity
- D. Air resistance
Why: Friction between the sprinter's feet and the ground provides the necessary force to propel the sprinter forward.
Q2. Which of the following is a vector quantity?
- A. Speed
- B. Distance
- C. Displacement ✓
- D. Time
Why: Displacement is a vector quantity because it has both magnitude and direction.
Q3. What happens to the acceleration of an object if the net force acting on it increases, while the mass remains constant?
- A. It decreases
- B. It increases ✓
- C. It remains the same
- D. It becomes zero
Why: According to Newton's second law (F = ma), if the net force increases and mass is constant, acceleration increases.
Q4. Which of the following best describes inertia?
- A. The tendency of an object to resist changes in motion ✓
- B. The force of gravity acting on an object
- C. The property of an object that determines its ability to float
- D. The rate at which an object changes its velocity
Why: Inertia is the tendency of an object to resist changes in its state of motion.
Q5. What is the main purpose of a runner leaning forward while turning?
- A. To increase speed
- B. To reduce friction
- C. To maintain balance and provide centripetal force ✓
- D. To decrease air resistance
Why: Leaning forward helps a runner maintain balance and provides the necessary centripetal force to make the turn.

Module 5: Energy and Power in Sport
Energy and Power in Sport
Knowledge check
Q1. What is the SI unit of energy?
- A. Newton
- B. Joule ✓
- C. Watt
- D. Pascal
Why: The joule is the standard unit of energy in the International System of Units (SI).
Q2. Which of the following is a measure of power?
- A. Force
- B. Work
- C. Energy per unit time ✓
- D. Distance
Why: Power is defined as the rate at which work is done or energy is transferred, so it is measured in energy per unit time.
Q3. When a sprinter accelerates from rest to maximum speed, what type of energy is primarily converted into kinetic energy?
- A. Thermal energy
- B. Chemical energy ✓
- C. Electrical energy
- D. Potential energy
Why: During muscle activity, chemical energy stored in the body is converted into kinetic energy as the sprinter moves.
Q4. Which of the following best describes the relationship between work and energy?
- A. Work is the same as energy
- B. Work is the transfer of energy ✓
- C. Work is the storage of energy
- D. Work is the destruction of energy
Why: Work is the process of transferring energy from one object to another through the application of force over a distance.
Q5. What is the formula for calculating power?
- A. Power = Work × Time
- B. Power = Force × Distance
- C. Power = Energy / Time ✓
- D. Power = Mass × Acceleration
Why: Power is calculated by dividing the amount of energy used by the time taken to use it, which is expressed as Energy divided by Time.
