Worked answers to every in-text and exercise question from Chapter 5, 'Exploring Forces', of the NCERT Class 8 Science textbook 'Curiosity'.

Your study route

In-text questions

Answer: Going uphill, a component of the Earth's gravitational pull acts against your motion, so you must pedal harder to overcome it.

Ask the child why it feels easier to pedal downhill: the same gravity component then helps the motion.

Exercise: Keep the Curiosity Alive (Pages 77–79)

- The Earth pulls every object towards itself with the force of gravity.
- On flat ground, gravity acts perpendicular to your motion, so it does not directly oppose your pedalling.
- On a slope, a part of the gravitational pull acts along the slope, against your direction of motion.
- You therefore have to apply extra force to keep moving forward and upward.
