## What is gravitational force what happens to the gravitational force between two objects when the distance between them is I halved and II doubled?

when the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.

## What is the gravitational force between two 1 kg objects that are 1’m apart?

For example, two 1.0-kg masses located 1.0 meter apart exert a force of 6.7×10−11N 6.7 × 10 − 11 N on each other. This is the weight of a typical grain of pollen.

What is the gravitational force between two 15 kg packages that are 35 cm apart?

Gravitational Force What is the gravitational force between two 15-kg packages that are 35 cm apart? What fraction is this of the weight of one package? Because the weight is mg 147 N, the gravitational force is 8.210 10 or 0.82 parts per billion of the weight.

How do you calculate gravitational force?

Find out how to calculate gravitational forces We can do this quite simply by using Newton’s equation: forcegravity = G × M × mseparation2 . Suppose: your mass, m, is 60 kilogram; the mass of your colleague, M, is 70 kg; your centre-to-centre separation, r, is 1 m; and G is 6.67 × 10 -11 newton square metre kilogram-2.

### What is the gravitational force between two objects?

Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.

### What happened to the gravitational force between two objects?

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

What is the gravitational force of 1 kg?

1 kg on the surface of the Earth weighs 9.80665 N, because 1 kg × 9.80665 m/s = 9.80665 N. In daily life on Earth we take: 1 newton (force) ≈ 1/9.80665 kg = 0.10197 kg ≈ 102 grams (weight). 1 kilonewton (force) = 1000 N ≈ 1000/9.80665 kg = 102 kg (weight).

What is the gravitational force between two point masses of 1 kg and 2 kg kept 1’m apart?

13.34×10−11N.

#### What is the satellite’s period in terms of the Moon’s period TM?

Kepler’s third law can be used to calculate the period of a body orbiting the Earth. For the Moon T=1 and a=1 . Taking the square root gives T=0.35355 lunar months.

#### How did Henry Cavendish find the value of g?

G is a constant that must be determined experimentally. In 1798 Cavendish measured the force between attracting lead spheres with a torsion balance. He knew the masses of the spheres and how far apart they were. He carefully measured the force between them, which allowed him to calculate G.

How much is the gravitational force?

The nominal “average” value at Earth’s surface, known as standard gravity is, by definition, 9.80665 m/s2.
