if the separation between two masses is doubled, does the gravitational force between them increase or decrease? By what factor?

Answers

When the separation between two masses is doubled, the gravitational force between them decreases by 4.

What is meant by gravitational force ?

Gravitational force is defined as the force of attraction experienced by a body due to the gravity of earth.

Here,

The separation between two masses is doubled.

That means the distance, r₂ = 2r₁

We know that the equation of gravitational force is given by,

F = GMm/r²

where G is the gravitational constant

From the equation, we know that the gravitational force obeys the inverse square law.

That means the gravitational force is inversely proportional to the square of the distance between the masses.

So, F \alpha 1/r²

Therefore,

F₂/F₁ = (r₁/r₂)²

F₂ = F₁(1/2)²

F₂ = F₁/4

Hence,

When the separation between two masses is doubled, the gravitational force between them decreases by 4.

Answer:

increase by a factor of 4.

Explanation:

If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).

Which of the following is NOT supported by Newton's Second Law?1 The mass of an object will change depending on the force acting on it

2 The greater the force applied on an object, the greater it's acceleration

3 You can find the mass of an object if you know it's acceleration and the forces acting on it

4 Force is equal to the product of mass and acceleration

Answers

Answer:

1. The mass will change depending on the force.

Explanation:

We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:

                     F = ma

Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.

In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa

Since the moon has less mass then the earth what happens to objects on the moon A.They fall slower
B.they fall faster
C.they don’t fall
D.They fall at the same rate as they do on earth

Answers

A) They move slower


Gravity force is determined by mass and the size of the moon. Since the mass of the moon is significantly lower than the mass of Earth, it will pull objects slower. The only object that would fall faster on the moon than on earth is a sheet of paper since there is much, much less air resistance to affect its terminal velocity the way it does on the earth.

Newton's _____ Law states that an object's acceleration is directlyrelated to the net force applied and inversely related to the mass of the object.​

Answers

Answer:

Newton's second Law states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object.​

Explanation:

Newton's second law states that when force is applied on an object, then it causes acceleration which is directly dependent on the net force applied and varies inversely with the mass of the object.

This law gives us the following equation:

F=ma

where F represents net force applied, m represents mass of the object and a represents acceleration caused.

The above equation can be rearranged to:

a=(F)/(m)

This equation shows that acceleration is directly dependent on net force and inversely dependent on mass of the body.
