Answers

 

Question 1: Fill in the Blanks

  1. The change in the position of an object with time is called motion.
  2. The motion of a pendulum is an example of oscillatory motion.
  3. A car moving on a straight road is an example of linear motion.
  4. A magnet attracts iron objects.
  5. A pulley is a simple machine that consists of a wheel with a rope.

Question 2: Match the Following

  1. Rotational motion - b. Fan blade
  2. Linear motion - c. Car on a road
  3. Oscillatory motion - a. Swing
  4. Periodic motion - d. Earth’s revolution around the sun
  5. Chemical energy - e. Energy in food

Question 3: Short Answer Questions

  1. What is force?
    Ans: Force is a push or pull that changes the state of motion or shape of an object.

  2. What is gravitational force? Give an example.
    Ans: Gravitational force is the force of attraction between two objects due to their mass. An example is the Earth's gravity pulling objects towards the ground.

  3. What are the different forms of energy?
    Ans: The different forms of energy are kinetic energy, potential energy, thermal energy, chemical energy, electrical energy, and nuclear energy.

  4. How does friction help us in walking?
    Ans: Friction between our feet and the ground prevents slipping and allows us to walk by providing the necessary grip.

Question 4: Long Answer Questions

  1. Explain different types of motion with examples.
    Ans:

    • Linear Motion: Motion in a straight line, e.g., a car moving on a road.
    • Rotational Motion: Motion around a fixed axis, e.g., a fan blade rotating.
    • Oscillatory Motion: Back and forth motion, e.g., a pendulum swinging.
    • Periodic Motion: Motion that repeats at regular intervals, e.g., the Earth's revolution around the Sun.

  2. How does energy transformation take place in daily life?
    Ans: Energy transformation occurs in many daily activities:

    • In an electric bulb, electrical energy transforms into light and heat energy.
    • In a car engine, chemical energy from fuel converts into mechanical energy.
    • In plants, sunlight energy transforms into chemical energy through photosynthesis.
    • In a human body, food energy is converted into kinetic energy for movement.
