Question

1. complete the sentence below.

the air friction acting on a baseball causes it to curve as it is pitched to the catcher. this is a result of

• choose the correct answer -
• choose the correct answer -

newtons 1st law
newtons 2nd law
newtons 3rd law
the universal law of gravitation
clear all

Explanation:

Newton's 2nd law states that force equals mass times acceleration ($F = ma$). The air friction (a force) acting on the baseball causes a change in its velocity (acceleration), making it curve. This is in line with Newton's 2nd law which relates force and acceleration. Newton's 1st law is about objects maintaining their state of motion unless acted on by a force (more about inertia). Newton's 3rd law is about action - reaction pairs. The Universal Law of Gravitation is about the gravitational force between two masses.

Answer:

Newton's 2nd law
