Gravitation ch 9 physics formulas in an other one

What is gravitation?

Gravitation is a natural phenomenon by which all things with mass are attracted to one another.

Who formulated the law of universal gravitation?

Sir Isaac Newton formulated the law of universal gravitation.

What does the law of universal gravitation state?

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

What is gravitational force?

Gravitational force is the attractive force between two masses.

How is gravitational force calculated?

Gravitational force can be calculated using the formula F = G(m1*m2)/r^2, where G is the gravitational constant.

What is the gravitational constant (G)?

The gravitational constant is approximately 6.674×10^-11 N(m/kg)^2.

What is weight?

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration.

What is gravitational acceleration on Earth?

Gravitational acceleration on Earth is approximately 9.81 m/s².

What are gravitational fields?

Gravitational fields are regions around a mass where other masses experience a force of gravitation.

What is escape velocity?

Escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a celestial body.
