Gravity Stuff 1

Front

What happens to the gravitational attraction between a comet and the sun as the comet gets closer to the sun?

Back

It gets stronger.

Front

True or False: Earth and the moon are attracted to each other through a force called gravity.

Back

True.

Front

If Earth's mass suddenly became half of what it is now without changing the radius, what would happen to your mass?

Back

None of these are correct.

Front

What happens to the gravitational attraction between a comet and the sun as the comet heads back away into the outer areas of the solar system?

Back

It gets weaker.

Front

At a distance of over 14.4 billion miles from the sun, what is the gravitational force on Voyager I?

Back

Weak but greater than zero.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

What is the formula for gravitational force?

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 the centers.

Front

What is the gravitational constant (G)?

Back

G = 6.674 × 10^-11 N(m/kg)^2.

Front

Explain how distance affects gravitational attraction.

Back

Gravitational attraction decreases as the distance between two objects increases.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force is directly proportional to the product of the masses of the two objects.
