5 - Gravity & Circular Motion | Gravitation Flashcard

Front

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

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 their centers.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2, a constant used in the calculation of gravitational force.

Front

How does mass affect gravitational force?

Back

Gravitational force is directly proportional to the product of the masses; as mass increases, gravitational force increases.

Front

How does distance affect gravitational force?

Back

Gravitational force is inversely proportional to the square of the distance between the centers of two masses; as distance increases, gravitational force decreases.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object (measured in kg), while weight is the force exerted by gravity on that mass (measured in Newtons).

Front

What is the surface gravity of a planet?

Back

Surface gravity is the gravitational acceleration experienced at the surface of a planet, influenced by the planet's mass and radius.

Front

If an object has a mass of 25 kg on Earth, what is its mass on Mars?

Back

Its mass remains 25 kg; mass does not change with location.

Front

What is the relationship between gravitational force and the distance between two objects?

Back

Gravitational force decreases as the distance between two objects increases.

Front

What type of force is gravity?

Back

Gravity is always an attractive force between two masses.
