Two objects, A and B, experience the same net force. Object A accelerates at twice the rate of object B. Therefore the
A) mass of A is twice that of the mass of B.
B) mass of A is half that of the mass of B.
C) mass of A is one-quarter that of the mass of B.
D) mass of A is four times that of the mass of B.

Question

Quizplus · Accepted Answer

According to Newton's second law of motion, acceleration is inversely proportional to mass when the force is constant. Therefore, if object A accelerates at twice the rate of object B under the same force, the mass of A must be half that of B.

Two Objects, a and B, Experience the Same Net Force
