Gravity, Electricity and Magnetism

Front

What happens to the gravitational force between two objects if the distance between them is tripled?

Back

The gravitational force decreases to 1/9 of its original value.

Front

What happens to the gravitational force if the mass of one object is doubled?

Back

The gravitational force doubles.

Front

How does increasing the distance between two objects affect the gravitational force?

Back

The gravitational force decreases.

Front

What is the nature of the force between two north poles of magnets?

Back

They will repel each other.

Front

What happens when a north pole and a south pole of magnets are placed near each other?

Back

They will attract each other.

Front

Which force is always attractive and never repulsive?

Back

Gravitational Force.

Front

What is the formula for gravitational force between two masses?

Back

F = G * (m1 * m2) / r^2, where G is the gravitational constant.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses.

Front

What is the effect of distance on gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of the two masses.
