Universal Law of gravitation & Free Fall

Front

What is the Universal Law of Gravitation?

Back

The Universal Law of Gravitation 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 free fall?

Back

Free fall is any motion of a body where gravity is the only force acting upon it.

Front

How does the speed of a freely falling object change over time?

Back

The speed of a freely falling object increases by approximately 9.8 m/s for each second of fall due to the acceleration of gravity.

Front

If an object falls for 6 seconds, what is its speed?

Back

After falling for 6 seconds, the speed of the object will be approximately 60 m/s.

Front

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

Back

If the distance between two objects is doubled, the gravitational force between them becomes one-fourth of the original force.

Front

What is the formula for gravitational force?

Back

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

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.8 m/s².

Front

What is the significance of the gravitational constant (G)?

Back

The gravitational constant (G) is a proportionality factor used in the equation of gravitational force, which quantifies the strength of gravity in the universe.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the effect of increasing distance on gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases; specifically, it is inversely proportional to the square of the distance.
