A push on a 1-kg brick accelerates it. Neglecting friction, to equally accelerate a 10-kg brick, one would have to push with
A) one tenth the amount of force.
B) just as much force.
C) 100 times as much force.
D) 10 times as much force.
E) none of these

Quizplus · Accepted Answer

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Therefore, to achieve the same acceleration for a 10-kg brick as a 1-kg brick, one would need to apply 10 times the amount of force.
