Section F – Long Answer Questions (Separate Questions and Answers)

Q1: Explain the difference between contact and non-contact forces with examples.
Answer: Contact forces occur when two objects touch each other. Examples include pushing a chair, pulling a rope, friction between book and table, or tension in a string. Non-contact forces act without physical contact, such as gravity pulling objects towards Earth, magnetic force attracting iron, and electric forces between charged objects.

Q2: Describe kinetic and potential energy with suitable examples.
Answer: Kinetic energy is energy due to motion. Examples: moving bicycle, rolling ball, flowing river. Potential energy is stored energy due to position or configuration. Examples: stretched rubber band, water in a dam, book on a shelf. Potential energy can be converted into kinetic energy when the object moves.

Q3: Explain how friction can be both useful and harmful.
Answer: Friction opposes motion. It is useful because it allows vehicles to grip roads, helps us walk without slipping, and allows objects to be held firmly. It is harmful because it causes wear and tear of machine parts, reduces efficiency, and produces unwanted heat.

Q4: List different forms of energy and give real-life examples for each.
Answer:

  • Mechanical energy: moving car, spinning fan
  • Chemical energy: food, fuels
  • Electrical energy: electric current in appliances
  • Heat energy: fire, sunlight warming objects
  • Light energy: sunlight, torch
  • Sound energy: musical instruments, speaking
  • Potential energy: stretched rubber band, water in dam
  • Kinetic energy: rolling ball, flowing river

Q5: Explain the law of conservation of energy and provide one example.
Answer: Energy cannot be created or destroyed; it only changes form. Total energy remains constant. Example: In a pendulum, potential energy at the highest point converts to kinetic energy at the lowest point and back. Total energy of the system remains the same.

Section G – Case-Based Answers

Case 1: Friction; use smoother surface or wheels.
Case 2: Gravitational potential energy; converted to kinetic and then electrical energy.
Case 3: Rubber band has potential energy; toy has kinetic energy.

Section H – Diagram-Based Answers

  • Stretched spring: label spring, potential energy, direction of force.
  • Hydroelectric plant: water potential → kinetic → electrical energy; label dam, turbine, generator.
