multiple choice question\nhow does newtons second law of motion explain how a rocket blasts off from its launch pad?\no the force of the thrust downward pushes the rocket upward.\no the rocket keeps moving upward as long as there is a force acting on it.\no the heavier the rocket is, the more force is required for it to escape earths atmosphere.\no the rocket does not begin moving until a force acts on it.
Answer
Brief Explanations:
Newton's second law is (F = ma) (force equals mass times acceleration). A heavier rocket (larger mass (m)) needs a larger force (F) to achieve the necessary acceleration to escape Earth's atmosphere.
- The first option is related to Newton's third law (action - reaction).
- The second option is more about the concept of motion while a force is applied but not specifically highlighting the (F = ma) relationship.
- The fourth option is related to Newton's first law (an object at rest stays at rest until a force acts on it).
Answer:
The heavier the rocket is, the more force is required for it to escape Earth's atmosphere.
