Question

During study group Mary and Ben were arguing about a question on the practice test. The question said "True or False: The amount of mass of an object determines the amount of force that is needed to accelerate it." Mary said the answer was false, but Ben thinks it is true. Who is right? Justify your answer.

a.Mary is correct because according to Newton's first law it is unbalanced forces that cause an object to accelerate.

b. Ben is correct. According to Newton's 3rd law force is determined by mass.

c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.

d. Mary is correct because it is the type of force that determines the acceleration, not the mass.

Answer 1

c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.

Explanation:

We can answer this question by using Newton's second law of motion, which states that the net force applied on an object is equal to the product between the mass of the object and its acceleration. Mathematically:

$F=ma$

where

F is the net force

m is the mass of the object

a is its acceleration

From the equation, we notice that:

- The force is directly proportional to the mass of the object --> so if the mass increases, the force needed to accelerate the object will increase too

Therefore, the correct answer is

c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.
