Answer:
Explanation:
Gravity is force of attraction between bodies that have masses. It is one of the most importance force in the universe that keeps it in an ordered form.
From what is obtainable from newtons law of universal gravitation, which states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them";
we know that;
- Gravity is a force of attraction that pulls objects toward the earth's center.
- It increases with mass between two objects
- It decreases as the distance increases
The amount of matter contained by an object is called mass.
A. mass
<u>Explanation:</u>
Mass is fundamentally a property of any physical amount and it is additionally the estimation of the resistance from the acceleration when force is applied on an object. The mass equals the quality of the gravitational force on a body.
Mass, in material science, the quantitative proportion of idleness, a crucial property of all matter. The greater the mass of a body, the littler the change created by an applied power. The mass of an object can be portrayed by its capacity to oppose a given power (we once in a while call this a body's inertial mass and subsequently mass is personally connected with the idea of inertia).
This is a straightforward result of Newton's second law where the power F, on a body is equivalent to the mass m, times the speeding up an, it encounters, ie:
F=ma or m=F/a
Mass of an object can not be zero but weight can be zero. The mass and weight of an object are different things.

<h2>
Hello!</h2>
The answer is:
The kinetic energy of the object is equal to 85 J.
<h2>
Why?</h2>
The kinetic energy involves the speed and the mass of an object in motion. We can calculate the following the work needed to speed an object (kinetic energy) using the equation:
Where,
m, is the mas of the object
v, is the speed of the object.
Now, we are given:
So, substituting and calculating the kinetic energy of the object, we have:
We have that the kinetic energy of the object is equal to 85 J.
Have a nice day!
