GRAVITY in space

Front

What is the relationship between the size of a planet and its gravitational pull?

Back

The larger a body (planet), the greater its gravitational pull.

Front

How does distance affect the gravitational force between two planets?

Back

The farther away two planets are, the less the gravitational force between them.

Front

What shape describes a planet's orbit around the sun?

Back

Elliptical.

Front

What is the attractive force between objects called?

Back

Gravity.

Front

What keeps planets in orbit and prevents them from drifting off into space?

Back

Gravity.

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

The gravitational constant (G) is approximately 6.674 × 10^-11 N(m/kg)^2.

Front

How does gravity affect the motion of celestial bodies in space?

Back

Gravity governs the motion of celestial bodies, causing them to orbit around larger masses like stars and planets.

Front

What is the difference between mass and weight in the context of gravity?

Back

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

Front

How does gravity vary on different planets?

Back

Gravity varies on different planets due to differences in mass and radius; larger planets generally have stronger gravity.
