Newton's universal gravity law

Front

What does Newton's universal law of gravitation state?

Back

It states that every point mass attracts every other point mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the formula for calculating gravitational force?

Back

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

Front

What is the value of the universal gravitational constant (G)?

Back

6.67 x 10^-11 N*m^2/kg^2.

Front

How does mass affect gravitational force?

Back

Gravitational force is directly proportional to the masses of the objects involved; as mass increases, gravitational force increases.

Front

How does distance affect gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two masses; as distance increases, gravitational force decreases.

Front

If the distance between two objects is doubled, how does the gravitational force change?

Back

The gravitational force becomes one-fourth of its original value.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What happens to your mass if the gravitational force changes?

Back

Your mass remains the same; only your weight changes with the gravitational force.

Front

What is the relationship between gravitational force and weight?

Back

Weight is the gravitational force acting on an object, calculated as W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s^2.
