Unit 2 Lesson 5 TCI Gravity and the Solar System

Front

What is a comet?

Back

A comet is a chunk of ice and dust that has a bright head and a long narrow tail.

Front

Which planet feels the most gravitational force from the sun?

Back

Mercury feels the most gravitational force from the sun.

Front

What happens to gravitational pull when an object has more mass?

Back

Objects with more mass have more gravitational pull.

Front

What two factors affect gravitational force?

Back

Size and distance affect gravitational force.

Front

What happens to gravity when the size of the Earth and the Sun increases?

Back

The gravity of both Earth and Sun increases.

Front

Define gravitational force.

Back

Gravitational force is the attraction between two objects with mass.

Front

What is the relationship between mass and gravity?

Back

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

Front

How does distance affect gravitational force?

Back

As distance increases, gravitational force decreases.

Front

What is the role of the Sun in the solar system?

Back

The Sun is the central star that provides gravitational pull to keep planets in orbit.

Front

What is an asteroid?

Back

An asteroid is a small rocky body that orbits the sun, primarily found in the asteroid belt.
