Question

More massive objects have a large gravitational force or weight. Why do heavier objects accelerate to the ground at the same rate as lighter ones? A) Smaller objects have more inertia. B) More massive objects have less inertia. C) All objects have the same pull of gravity on them. D) Heavier objects need a greater force to accelerate according to F=ma.

Answer 1

Answer:

D) Heavier objects need a greater force to accelerate according to F=ma.

Explanation:

The force of gravity acting on an object is equal to:

F = mg

where m is the mass of the object and g is the acceleration due to gravity. According to the formula, heavier objects (objects with greater mass, m) have a larger force of gravity acting on them.

However, the acceleration of an object towards the ground is given by:

$a=\frac{F}{m}$

therefore, we see that if the object is heavier (larger mass, m), the force of gravity (F) must also be larger in order to have the same acceleration a.

Answer 2

Is DD. Heavier objects need a greater force to accelerate accoirding to f ma.
