Gravity, Electricity and Magnetism

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What factors affect gravitational force?

Back

Gravitational force is affected by the masses of the objects and the distance between them.

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What happens to gravitational force if the distance is tripled?

Back

The gravitational force becomes 1/9 as much.

Front

What happens to gravitational force if the distance is doubled?

Back

The gravitational force becomes 1/4 as much.

Front

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

Back

The gravitational force doubles.

Front

What is the formula for gravitational force?

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.

Front

What is the gravitational constant (G)?

Back

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2, a proportionality factor in the gravitational force equation.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the effect of increasing mass on gravitational force?

Back

Increasing the mass of either object increases the gravitational force between them.
