A force of 1 N accelerates a mass of 1 kg at the rate of 1 m/s2. The acceleration of a mass of 2 kg acted upon by a force of 2 N is
A)half as much.
B)twice as much.
C)the same.
D)none of the above

Question

Quizplus · Accepted Answer

The acceleration a mass experiences due to a force is given by Newton's second law, $F = ma$, where $F$ is the force, $m$ is the mass, and $a$ is the acceleration. For a 1 kg mass with a 1 N force, the acceleration is $1 m/s^2$. For a 2 kg mass with a 2 N force, the acceleration is also $1 m/s^2$ ($2 N / 2 kg = 1 m/s^2$), meaning the acceleration is the same.
