Question

Liz puts a 1 kg weight and a 10 kg on identical sleds. She then applies a 10N force to each sled. Which does not explain why the smaller weight accelerate faster?

A) The larger mass spends more force overcoming inertia.
B) The smaller weight exerts less frictional force to overcome.
C) The acceleration depends directly on the mass of the object.
D) The motion of the sled relates to action of unbalanced forces.

Answer 1

c. the acceleration depends directly on the mass of the objects

Step-by-step explanation:

Answer 2

Answer: C

Step-by-step explanation:
The acceleration does not depend directly on the mass of the object.

Newton's Law is Force = Mass x Acceleration.
Therefore, Acceleration = Force/Mass

The same force is applied in both cases.
Therefore acceleration is inversely proportional to mass.
As mass decreases, acceleration increases.
