If the distance between two objects decrease and the masses of the objects remains the same, then the force of gravity between the two objects(1 point)
increases.
Gravity is a force between any two objects with mass. Why doesn't a person feel a gravitational force between him/herself and another person? (1 point)
A person does feel the gravitational force between themselves and another person. However, the force between two people is very small compared to the force of gravity between a person and the Earth. This is due to the fact that the mass of a person is much smaller than the mass of the Earth. As a result, the gravitational force between two people is not significant enough to be easily perceived or noticed.
Four wrestlers step on a scale for a tournament. Wrestler A weighs in at 170 pounds; wrestler B weighs in at 168 pounds; wrestler C weighs in at 171 pounds; and wrestler D weighs in at 169 pounds. Which of these wrestlers experiences the greatest force due to gravity? (1 point)
The force due to gravity experienced by an object depends on its mass. Since the masses of objects A, B, C, and D are not provided, we cannot determine which wrestler experiences the greatest force due to gravity based on their weights alone.
To determine the force of gravity between two objects, we need to use Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Mathematically, this can be expressed as:
F = G * (m1 * m2) / r^2
Where:
F is the force of gravity,
G is the gravitational constant,
m1 and m2 are the masses of the objects, and
r is the distance between the centers of the objects.
Now, if the distance between the two objects decreases while the masses remain the same, we can see how it affects the force of gravity.
Let's assume the initial distance between the objects is "r1," and the final distance is "r2." If r2 is smaller than r1, then the force of gravity will increase. This is because as the distance between the objects decreases, the denominator of the equation (r^2) becomes smaller, resulting in a larger value for the force of gravity.
In conclusion, if the distance between two objects decreases and the masses of the objects remain the same, the force of gravity between them will increase.
