Gravitational Force Unit Test

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two objects with mass. It depends on the masses of the objects and the distance between them.

Front

What happens to gravitational force when distance increases?

Back

The gravitational force decreases. Specifically, if the distance is doubled, the gravitational force is quartered.

Front

True or False: There is no gravity in space.

Back

False. Gravity exists everywhere in space, although it may be weaker at greater distances from massive objects.

Front

What determines the strength of gravitational force between two objects?

Back

The strength of gravitational force is determined by the masses of the objects and the distance between them.

Front

What is mass?

Back

Mass is a measurement of how much matter is present in an object.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, which depends on the object's mass and the gravitational acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming constant gravitational acceleration.

Front

What is the formula for 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 value that describes the strength of the gravitational force in the formula, approximately equal to 6.674 × 10^-11 N(m/kg)^2.

Front

What is the effect of mass on gravitational attraction?

Back

The greater the mass of an object, the stronger its gravitational attraction to other objects.
