7.10B Gravity and the Solar System

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does mass affect gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

What happens to gravity as distance increases?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the role of gravity in the solar system?

Back

Gravity pulls celestial bodies together, keeping planets in orbit around the Sun and moons in orbit around planets.

Front

Who formulated the law of universal gravitation?

Back

Sir Isaac Newton formulated the law of universal gravitation.

Front

What is the relationship between mass and distance in gravity?

Back

Gravity depends on both mass and distance; it increases with mass and decreases with distance.

Front

True or False: The weight of an object changes on different planets due to gravity.

Back

True; weight changes based on the gravitational pull of the planet.

Front

What is the gravitational pull of the Sun compared to Earth?

Back

The Sun's gravitational pull is much stronger than Earth's due to its larger mass.

Front

What force pulled the solar system together?

Back

Gravity pulled the solar system together from a cloud of gas and dust.

Front

What is the effect of gravity on objects in space?

Back

Gravity keeps objects in orbit and affects their motion in space.
