A push on a 1-kg brick accelerates it. Neglecting friction, equally accelerating a 10-kg brick requires
A)just as much force.
B)10 times as much force.
C)100 times as much force.
D)one-tenth the amount of force.
E)none of the above

Question

Quizplus · Accepted Answer

According to Newton's second law of motion, force equals mass times acceleration (F = ma). To achieve the same acceleration for a 10-kg brick as a 1-kg brick, 10 times as much force is required, because the mass is 10 times greater.
