Gravity

Front

What is the fundamental property that allows objects to exert gravitational force?

Back

Mass.

Front

What is the primary force that keeps planets in orbit around the sun?

Back

The sun's gravitational pull.

Front

Who formulated the law of universal gravitation?

Back

Isaac Newton.

Front

How is mass defined in physics?

Back

The amount of matter that something has.

Front

Which celestial body has the greatest gravitational influence on an astronaut in the International Space Station?

Back

Earth.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with mass.

Front

What is the formula for calculating gravitational force between two objects?

Back

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 gravitational constant (G)?

Back

Approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What is weight in terms of gravitational force?

Back

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