Question

1. assuming the acceleration is the same for each of the following objects, which will require more force to cause the acceleration?

a lion
a dog
an elephant
a mouse

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).

Step2: Compare masses

Given \(a\) is the same. Since \(F\propto m\) (force is proportional to mass), the object with the largest mass will require the most force. An elephant has a larger mass than a lion, a dog, and a mouse.

Answer:

an elephant
