Question

a line of dominos is knocked down. which explanation is true? (1 point) an increase in acceleration caused an increase in force. an increase in force caused an increase in acceleration. an increase in acceleration caused a decrease in force. an increase in force caused a decrease in acceleration.

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\) (where \(F\) is force, \(m\) is mass, and \(a\) is acceleration). Mass \(m\) of a domino is constant.

Step2: Analyze the relationship between \(F\) and \(a\)

From \(F = ma\), when \(m\) is constant, \(F\) and \(a\) are directly proportional. So an increase in force \(F\) will cause an increase in acceleration \(a\).

Answer:

An increase in force caused an increase in acceleration.
