Ans. Mass.
9. How does inertia depend on the mass of the body?
10. Give an example to demonstrate greater is mass more will be inertia.
11. It is difficult to move a body of more mass, why?
no
12. Two equal and opposite forces act on a body at rest. Will the body move? Explam in hel
no
13. Two equal and opposite forces act on a body in the moving state. Can it be stopped? Explain.
Ans. No
14. A train moves with uniform velocity inspite of its weight and equal reactional force. What is the net force on the
along y-axis?
Ans. Zero.
15. Why does a coin placed on card, drop in tumbles when the card is rapidly flicked with the finger?
Y6. Why one should move in the same direction when coming from the slow moving train at the station?
17. It is easy to run before taking a long jump.
B
18. Explain in brief when net force on a body is zero, body may be in state of motion as well as in state of rest
19. Inertia is inherent or external property of a body. Explain.
20. Why Newton's first law is also known as law of inertia?​

Answer 1

Answer:

9. Inertia is the basic property of any body to resist its current position or situation or state.

This property is directly depend on the mass of the body.

20. Newton's first law also known as the Law of Inertia because Newton's first law recognise that everybody has some inertia.
