Gravitational Forces

Front

What is gravitational force?

Back

The amount of attraction between two objects due to their masses, even when they are not in contact.

Front

What happens to gravitational force when the mass of one or both objects increases?

Back

The gravitational force increases.

Front

How does distance affect gravitational force?

Back

Increasing the distance between two objects decreases the gravitational force.

Front

What is the formula for calculating gravitational force?

Back

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

Front

What is the gravitational constant (G)?

Back

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

Front

Why don't we feel the gravitational attraction of small objects around us?

Back

The masses of those objects are too small for the gravitational force to be noticeable.

Front

What is the effect of increasing the gravitational constant (G) on gravitational force?

Back

Increasing G would increase the gravitational force between two objects.

Front

If two objects are moved further apart, what happens to the gravitational force?

Back

The gravitational force decreases.

Front

Calculate the gravitational force between a 10-kg object and a 20-kg object separated by 2 m.

Back

F_g = 6.67 * 10^-11 N(m/kg)^2 * (10 kg * 20 kg) / (2 m)^2 = 3.34 * 10^-10 N.

Front

What is the relationship between gravitational force and mass?

Back

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