Question

1. which of the following is likely to happen according to newtons first law of motion?

select all that apply.
a. your bike stops moving forward.
b. your body flies forward.
c. the pedals fall off your bike.
d. the rock may move backward.

Explanation:

• Option A: When the bike hits the rock (external force), it stops moving forward as per Newton's First Law.
• Option B: The body was in motion with the bike. When the bike stops (due to external force from the rock), the body (due to inertia) tends to continue moving forward (Newton's First Law).
• Option C: The pedals falling off is not related to Newton's First Law (which is about an object's state of motion and external forces affecting that state, not about parts detaching due to some random event not related to the law's context of motion - force interaction).
• Option D: A rock moving backward when hit by a bike (assuming normal bike - rock interaction in a forward - moving bike scenario) is not in line with Newton's First Law. The rock, if at rest initially, would tend to stay at rest unless a sufficient external force acts on it. But the normal outcome of a bike hitting a rock (bike moving forward) would be the rock maybe moving forward (if the bike's force overcomes static friction etc.), not backward.

Answer:

A. Your bike stops moving forward, B. Your body flies forward.
