Question

(iii) Match the following:
A
B
i. Inertia
a. Newton's third law of motion
ii. Action force and reaction force
b. Newton's second law of motion
c. Newton's first law of motion​

Answer 1

A: Inertia : It is defined as property of body due to which it continues in its state. Given by Newton's first law.

B Recoil of gun: for every action, there is an equal and opposite reaction. Newton's third law.

C: Momentum: Newton's second law states that, rate of change of momentum is directly proportional to applied force.

D 1kg m/s =10^3 gm * 10^2 cm / s = 10^5 gm cm/s

E : weight- unit is kg-force
