objects with more mass feels ??? because of the greater gravitational attraction to earth.

Heavier or more massive objects feel more "weight" because of the greater gravitational force acting upon them due to the Earth's gravitational attraction.

what would that look like in the original sentence though

Objects with more mass feel heavier because they experience a greater gravitational pull from the Earth.

Objects with more mass feel heavier because of the greater gravitational attraction to Earth. The force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them. So, when an object has more mass, it experiences a stronger gravitational pull towards the center of the Earth.

To understand this phenomenon, we can use Newton's law of gravitation, which states that the force of gravity (F) between two objects is given by the equation:

F = (G * m1 * m2) / r^2

Where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers. In this case, one of the objects is the mass we are referring to and the other is the Earth.

Since the mass of the Earth is significantly larger than the mass of most objects, the force of gravity between the Earth and an object is usually considered to act on the object only. This force is what we perceive as weight.

Therefore, when an object has more mass, the force of gravity acting on it is greater, making it feel heavier. It's important to note that weight is a measure of the force of gravity on an object, while mass is a measure of the amount of matter an object contains.
