Question

1. a baseball accelerates more when hit with a stronger bat swing. which law is demonstrated?

1. a balloon releases air downward and rises upward. what law is this?

1. a skateboarder pushes the ground backward and rolls forward. which law applies?

Explanation:

Question 37

Newton's Second Law (\(F = ma\)) states that acceleration (\(a\)) is directly proportional to force (\(F\)) and inversely proportional to mass (\(m\)). A stronger bat swing means a larger force applied to the baseball, leading to greater acceleration, which matches this law.

Newton's Third Law states that for every action, there is an equal and opposite reaction. The balloon pushes air downward (action), and the air pushes the balloon upward (reaction), causing it to rise.

Newton's Third Law applies here. The skateboarder pushes the ground backward (action), and the ground exerts an equal and opposite force forward (reaction), making the skateboarder roll forward.

Answer:

Newton's Second Law of Motion (Force = Mass × Acceleration, \(F = ma\))
