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 does gravity do to objects?

Back

Gravity attracts all objects towards one another.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with the mass of the objects involved.

Front

What happens to your mass if Earth's mass is cut in half?

Back

Your mass remains the same; mass is not affected by gravitational force.

Front

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

Back

The gravitational force is reduced to one-fourth of its original value.

Front

Which configuration results in the greatest gravitational force?

Back

Large masses close together result in the greatest gravitational force.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

Do all objects fall at the same rate in a vacuum?

Back

Yes, in a vacuum, all objects fall at the same rate regardless of their mass.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

What is the formula for gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r², 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.
