If there is no net force, there can be no acceleration.
She met him in her Physics class, listening attentively from his seat in the front row. What is there to know about the law of gravity or Newton’s laws of motion? Only abstract concepts made tangible by experiment. But she taught this to her class anyhow. Like she did not admit that opposites really do attract, and that objects inevitably fall, and that bodies of matter do not move unless something (or someone) exerts some kind of force on them.
The net force on an object is proportional to the acceleration that the object undergoes.
The interested look in his eyes made her uneasy. She felt like one of her peers in high school who fell head over heels in love with some cute teenage boy winking at them in the hallway. The boy’s eyes gleamed with admiration and when he smiled, she swooned over him.
