Two objects of different masses accelerate at the same rate. According to Newton’s second law of motion, the more massive object requires________.
A.less speed to accelerate
B.less force to accelerate
C.more force to accelerate
D.more distance to accelerate

Respuesta :

Newton's Second law of motion is

F = m * a   ( force = mass * acceleration).

So if a is constant   then a = F 1 / m1  and  a = F2 / m2  then

F1 /m1 = F2 /  m2 and if  m1 > m2 then

F1 must be greater than F2.

Answer is C.
