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

Quizplus · Accepted Answer

According to Newton's second law of motion, force is directly proportional to mass and acceleration. So, to produce the same acceleration on a 10-kg brick, we need to apply a force that is 10 times larger than the force applied on the 1-kg brick. Therefore, the correct answer is option B, 10 times as much.

A Push on a 1-Kg Brick Accelerates the Brick
