Question

1. in the balloon station, which of newtons laws explains why the straw thrusted forward when the balloon was released?

newtons first law of motion
newtons second law of motion
newtons third law of motion
law of conservation of energy

1. in the ping pong ball station, which of newtons laws explains why the red ball took more force to change its velocity than the ping pong ball?

newtons first law of motion
newtons second law of motion
newtons third law of motion
law of conservation of energy

Explanation:

Question 5

Newton's third law states that for every action, there is an equal and opposite reaction. When the balloon releases air (action), the straw is thrust forward (reaction), matching this law. The first law is about inertia, the second about force and acceleration, and the energy conservation law is not a Newton's motion law.

Newton's second law ($F = ma$) relates force, mass, and acceleration. A red ball (likely more massive than a ping - pong ball) needs more force to change its velocity (acceleration) because $F$ is proportional to $m$ when $a$ is constant. The first law is about inertia, the third about action - reaction, and energy conservation is not a Newton's motion law.

Answer:

C. Newton's third law of motion
