Equal and Opposite

by: Page Keeley and Rand Harrington

The purpose of this assessment probe is to elicit students’ ideas about pairs of forces that fit Newton’s third law. The probe is specifically designed to reveal whether students can identify third law force pairs as involving different objects. The probe is useful in determining whether students misinterpret the familiar colloquial expression of Newton’s third law, “For every action there is an equal and opposite reaction.”
