Newton’s first law of motion says that a moving body should continue to move forever, unless some external forces act on it. But a moving cycle comes to rest after some time if we stop pedaling it. Can you choose the correct reason for the stoppage of cycle?
i. Air resistance
ii. Gravitational pull of the earth
iii. Friction of the road
iv. Heat of the environment
Choose the correct option:
(iii) and (iv)
(i) and (iii)
(i) and (ii)
(ii) and (iii)

Answer:
According to Newton's first law, the only time the bicycle would stop, is if it is acted upon by an external force. This is the exact case that happens to make the bicycle to come to a stop. The external force in this case is the friction between the bicycle and the ground. The force of friction gradually reduces the moving force until it gets to zero and the bicycle stops moving.
