What is the law of universal gravitation?

Back

The law of universal 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

How does distance affect gravitational force?

Back

Gravitational force decreases as the distance between two objects increases. Specifically, if the distance is doubled, the gravitational force decreases by a factor of 4.

Front

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

Back

If the mass of one object is doubled, the gravitational force between the two objects also doubles.

Front

Define gravitational force.

Back

Gravitational force is the attractive force that exists between any two masses, which pulls them toward each other.

Front

What is the formula for calculating gravitational force?

Back

The formula for gravitational force (F) is F = G * (m1 * m2) / r^2, where 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

The gravitational constant (G) is a fundamental physical constant used in the calculation of gravitational force, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

Explain the concept of weight in relation to gravity.

Back

Weight is the force exerted by gravity on an object, calculated as the product of the object's mass and the acceleration due to gravity (W = m * g).

Front

How does gravity affect objects in free fall?

Back

In free fall, all objects experience the same acceleration due to gravity, regardless of their mass, leading to them falling at the same rate.

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object, while weight is the force exerted on that mass by gravity.

Front

What is the effect of gravity on the motion of planets?

Back

Gravity is the force that keeps planets in orbit around stars, such as the Earth orbiting the Sun, due to the gravitational attraction between them.
