What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between the centers of the two masses.

Front

What happens to the gravitational force when the distance between two masses is halved?

Back

The gravitational force increases by a factor of four, as it is inversely proportional to the square of the distance.

Front

Define gravitational constant (G).

Back

G is a universal constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

If two masses attract each other with a force of 10 N at a distance of 10 cm, what will be the force when the distance is reduced to 5 cm?

Back

40 N, because the force increases with the square of the distance decrease.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the two masses; as either mass increases, the force increases.

Front

Explain the concept of action and reaction in gravitational force.

Back

For every action, there is an equal and opposite reaction; both masses exert equal gravitational forces on each other.

Front

What is the significance of the distance in gravitational force calculations?

Back

The distance between the masses significantly affects the force; as distance decreases, the force increases rapidly.

Front

How does the gravitational force between two objects change if one mass is doubled?

Back

The gravitational force also doubles, as it is directly proportional to the mass.

Front

What is the effect of increasing both masses on the gravitational force?

Back

The gravitational force increases, as it is directly proportional to the product of the two masses.

Front

Define the term 'mass' in the context of gravitational force.

Back

Mass is a measure of the amount of matter in an object, which influences the strength of the gravitational force it exerts.
