Law of Gravitation

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

Who is credited with the law of universal gravitation?

Back

Newton.

Front

If two objects are attracted to each other with 36 N of gravitational force, what would the force be if the distance between them were doubled?

Back

9 N.

Front

What is the gravitational force between a 70 kg person and a 5000 kg truck at a distance of 2m?

Back

0.000005836 N.

Front

If the Earth exerts a 500 N force on a man, what force does the man exert on the Earth?

Back

500 N.

Front

Define the law of universal gravitation.

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 gravitational constant, m1 and m2 are the masses, and r is the distance between the centers.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

Explain how distance affects gravitational force.

Back

As the distance between two objects increases, the gravitational force between them decreases, following an inverse square relationship.

Front

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

Back

The gravitational force between the two objects is also doubled.
