Question

1. asteroid deflection

directions: explain how nasas plan to shoot an asteroid with a heavy spacecraft could be enough to deflect an asteroid away from earth?

1. choose the best rule or law to use for this phenomenon. explain the rule or law below.

newtons 1st law newtons 2nd law newtons 3rd law

Explanation:

Newton's 2nd Law states that force \(F = ma\) (where \(m\) is mass and \(a\) is acceleration). When a heavy spacecraft collides with an asteroid, it applies a force on the asteroid. According to \(F = ma\), this force will cause a change in the asteroid's velocity (acceleration), which can deflect it. Newton's 1st Law is about objects staying in their state of motion unless a force acts (not directly about the interaction causing deflection here). Newton's 3rd Law is about action - reaction pairs (e.g., asteroid exerts a force on spacecraft and vice - versa, but the key for deflection is the force causing acceleration as per 2nd Law).

Answer:

Newton's 2nd Law.
