Universal Law of Gravity

Front

What is the Universal Law of Gravity?

Back

The Universal Law of Gravity states that every mass attracts every other 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 factors affect the gravitational force between two objects?

Back

The two main factors that affect the gravitational force are the masses of the objects and the distance between them.

Front

If the mass of one object is doubled, what happens to the gravitational force?

Back

The gravitational force doubles.

Front

What happens to the gravitational force if the distance between two objects is doubled?

Back

The gravitational force is cut to a quarter (1/4) of its original value.

Front

When is the gravitational force between two objects the greatest?

Back

The gravitational force is greatest when the masses of both objects are large and the objects are close together.

Front

What is the relationship between mass and gravitational attraction?

Back

Gravitational attraction increases with greater mass.

Front

What is the relationship between distance and gravitational attraction?

Back

Gravitational attraction decreases as the distance between two objects increases.

Front

True or False: Gravity only acts between planets.

Back

False. Gravity acts between any two masses, regardless of their size.

Front

What is the effect of gravity on objects in free fall?

Back

Objects in free fall experience acceleration due to gravity, which causes them to fall towards the Earth at approximately 9.81 m/s².

Front

What is weight?

Back

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